¶ 1. N. PATRICK CROOKS, J.

G. Jeffrey Totsky and Kristine Totsky, the petitioners, seek review of a published decision of the court of appeals, Totsky v. Riteway Bus Serv. Co., 220 Wis.2d 889, 894, 584 N.W.2d 188 (Ct.App. 1998), which reversed a Milwaukee County Circuit Court judgment. The judgment vacated a jury verdict that found a Riteway school bus driver was not negligent in going through a stop sign, a violation of Wis. Stat. § 346.46(1) (1991-92). The jury was instructed on the emergency doctrine as set forth in Wis JI-Civil 1105A. It apparently accepted the emergency doctrine in finding no negligence in the actions of the bus driver, Sharon Y. Williams, who skidded through the stop sign when the bus hit a patch of ice. In skidding through the stop sign, Williams' bus collided with Jeffrey Totsky's vehicle. After the jury found Williams was not negligent, the circuit court, the Honorable Michael W. Skwierawski presiding, entered a judgment in favor of the Totskys on their renewed motion for directed verdict and conditionally granted a new trial.

¶ 2. The court of appeals reversed, holding that "the emergency doctrine can apply [in a negligence per se action] if a violation of the safety statute is caused by a loss of management and control through no fault of the driver, presuming the other requirements for invoking the emergency doctrine are met." Totsky, 220 Wis.2d at 903. The court of appeals also held that credible evidence supported the "application of the emergency doctrine in this case." Id. at 904. We affirm the court of appeals' decision. The emergency doctrine applies to a violation of Wis. Stat. § 346.46(1) under the facts of this case, because a violation of § 346.46(1) is concerned with an issue of management and control. We further hold that two of the subrogated parties in this case, the city of Milwaukee and Maxicare Health Insurance Corporation, were not required to file a separate petition for review to preserve their subrogated interests on appeal, because they stipulated to waive their rights to participate at trial and to be bound by the judgment. However, State Farm Mutual Automobile Insurance, which did not enter into such a stipulation, was required to file an individual petition for review to preserve on appeal its subrogated interest, which is separate from the Totskys' claim.

I.

¶ 3. This case revolves around an accident where a bus skidded through an intersection on ice and collided with another car. The accident occurred just before 7:00 a.m. on February 10, 1993, at the intersection of Morgan Avenue and 80th Street in the city of Milwaukee. Morgan Avenue is an arterial roadway and does not contain any stop signs where it intersects 80th Street. A stop sign controls the northbound lane of 80th Street. Jeffrey Totsky (Totsky) was driving to work heading east on Morgan Avenue. At that same time, Sharon Williams (Williams) was driving a Riteway school bus north on 80th Street.

¶ 4. Williams began work that day at 6:00 a.m. Before leaving the bus yard, she checked the general condition of the bus, including the brakes, and was satisfied that the bus was working properly. Williams noticed that the roads looked damp, but she knew that some ice existed on the roads as well. She was on her first route to pick up children when she initially skidded. Her bus skidded a couple of times, but each time, she apparently could see the ice on the road before she encountered the skid. The first encounter on the ice caused the bus to slide to the side approximately one or two feet. The second skid was similarly minimal.

¶ 5. Totsky noticed that the road looked wet as he left for work, but he did not skid before the accident or encounter slippery conditions. He also testified at the trial that the road did not look slippery near where the bus stopped after the accident; it just looked wet.

¶ 6. Williams saw the stop sign for northbound traffic as she approached the intersection of 80th Street and Morgan Avenue. When she was approximately 100 feet from the stop sign, she began to apply her brakes. She estimated at trial that she was travelling at about 12-14 miles per hour when she began to apply the brakes, and that the road looked wet, not icy. The bus began to skid when Williams braked. As the bus skidded, she pumped the brakes and tried to turn the wheel of the bus into the skid. However, she was unable to stop the bus. Robert Krenz, Riteway's expert, estimated that when Williams began to skid, the bus was travelling between 16-23 miles per hour, and struck the Totsky vehicle at a speed between 11-16 miles per hour.

¶ 7. The bus skidded completely through the parking lane and into the intersection. Totsky saw the bus skidding through the intersection and accelerated in an attempt to avoid a collision. The bus struck Totsky's vehicle on the right rear corner, denting the right rear fender. Upon impact, Totsky's vehicle went into a spin turning clockwise, only stopping when it struck a signpost broadside. Krenz estimated that Totsky was driving at 8-12 miles per hour when his vehicle hit the signpost.

¶ 8. When the bus hit the car, Totsky was knocked out of the shoulder harness into the passenger seat, but the lap belt still secured his hips and legs. He attempted to sit up and counter-steer out of the spin, but as the vehicle hit the curb and signpost, his head and body slammed into the left front door. Totsky almost immediately felt pain in his back, for which he later took painkillers and muscle relaxants. He ultimately completed three months of therapy, was treated by several doctors, and missed eight months of work.

¶ 9. Williams had picked up two children prior to the accident, but neither Williams nor the children was injured during the collision.

¶ 10. The Totskys sued Riteway. Before the trial, both Maxicare Health Insurance Corporation (Maxicare) and the city of Milwaukee waived their right to participate at trial. However, State Farm Mutual Automobile Insurance (State Farm) did not waive its right to participate at trial.

¶ 11. In November 1996, the case was tried to a jury. At the close of the evidence, the Totskys moved for a directed verdict on the issue of Williams' negligence. The court took the motion under advisement, and permitted the case to go to the jury.

¶ 12. Among the jury instructions given were Wisconsin Civil Jury Instructions 1105-Management and Control, 1105A-Emergency Doctrine, 1280-Skidding, and 1055-Lookout. The first question of the special verdict asked: "Was Sharon Williams negligent in the operation of her vehicle on February 10, 1993?" The jury responded "no." The jury also responded "no" to the third question: "Was G. Jeffrey Totsky negligent in the operation of his vehicle on February 10, 1993?" The jury thought that the following sums of money would reasonably compensate Totsky for his damages: $37,000 for past medical and hospital expenses; $60,000 for future medical and hospital expenses; $20,324 for past loss of earnings; $100,000 for loss of future earning capacity; and $50,000 for past and future pain, suffering, and disability. The jury further determined that $10,000 would reasonably compensate Kristine Totsky for the loss of consortium sustained by her.

¶ 13. Since the jury returned a verdict that neither Williams nor Totsky was negligent, the Totskys renewed their motion for a directed verdict. They also moved in the alternative for a new trial in the interest of justice and claimed that the verdict was against the weight of the evidence. Judge Skwierawski granted both motions.

¶ 14. The court granted the motion for a directed verdict for several reasons. Williams was negligent per se, the court found, since she violated a safety statute. Moreover, the court found that the emergency doctrine could not excuse Williams' negligence as this case did not solely present an issue of management and control. Finally, she was negligent as a matter of law because her excessive speed produced the emergency that she encountered, and therefore, the emergency doctrine did not apply.

¶ 15. The circuit court also conditionally granted the motion for a new trial in the event that on appeal, the court's judgment would be reversed or vacated.

¶ 16. The court of appeals reversed both of the circuit court's rulings. Totsky, 220 Wis.2d at 894. The emergency doctrine can apply to the violation of a safety statute, which results in negligence per se, the court of appeals decided. Id. at 899. For support, it looked to La Vallie v. General Ins. Co. of Am., 17 Wis.2d 522, 117 N.W.2d 703 (1962), in which this court applied the emergency doctrine to a violation of a safety statute. The court of appeals explained that La Vallie stands for the proposition that if a driver's loss of management and control causes a violation of a safety statute, the emergency doctrine can apply, assuming the other prerequisites for the emergency doctrine also apply. Totsky, 220 Wis.2d at 903.

¶ 17. The court of appeals also distinguished Leckwee v. Gibson, 90 Wis.2d 275, 280 N.W.2d 186 (1979), a case the petitioners rely upon greatly. That case arguably precludes the use of the emergency doctrine in cases of a safety statute violation. Totsky, 220 Wis.2d at 903 n. 3. Leckwee was inapposite, the court of appeals recognized, because in Leckwee, the court did not even address the emergency doctrine issue, since it was not raised at the circuit court level. Id. (citing Leckwee, 90 Wis.2d at 289).

¶ 18. The court of appeals concluded that here credible evidence supports the application of the emergency doctrine.Totsky, 220 Wis.2d at 904. The alleged negligence related to management and control. Id. at 906. Credible evidence also supported the other two requirements for application of the emergency doctrine: the time in which Williams needed to act was "short enough to preclude action sufficient to avoid the accident," and she was free of negligence in causing the accident because she was unable to see the icy patch that made the bus skid. Id.

¶ 19. The court of appeals also addressed the issue of negligence as a matter of law. The circuit court had found Williams negligent as a matter of law since "she was going too fast and in view of the fact that she knew there was a danger that morning that ice existed on the roadways. . . ." Id. at 905. This finding was in error, the court of appeals stated, because a reasonable jury could have found, according to credible evidence, that Williams was driving between 10 and 16 miles per hour when she hit the ice patch that caused the skid. Id. Her speed was not excessive and, therefore, she was not negligent as a matter of law. Id.

¶ 20. The Totskys petitioned this court for review of the court of appeals' decision. The three subrogated parties, the city of Milwaukee, Maxicare, and State Farm, did not join the petition. Further, none of the subrogees filed a timely petition of their own. The Respondents therefore filed a motion to dismiss the subrogees as parties under Wis. Stat. § 808.10(1997-98) and Wis. Stat. § (Rule) 809.62(1997-98), claiming that the subrogees waived their right to a review of the claims. The subrogees did not respond to the Respondents' motion. Finally, the subrogees only filed briefs in opposition to the motion to dismiss when they were warned that the motion would be summarily granted absent a failure to respond.

II.

¶ 21. The first issue we address is whether the emergency doctrine can apply to a violation of Wis. Stat. § 346.46(1), the statutory section requiring vehicles to stop at stop signs. Interpretation of Wis. Stat. § 346.46(1) as it relates to the emergency doctrine presents a question of law. Burnett v. Hill, 207 Wis.2d 110, 118, 557 N.W.2d 800 (1997) (stating that statutory interpretation is a question of law). Questions of law are reviewed independently without deference to a circuit court's decision. Id.

¶ 22. The emergency doctrine excuses an individual from negligence. See Seif v. Turowski, 49 Wis.2d 15, 23, 181 N.W.2d 388 (1970). See also Geis v. Hirth, 32 Wis.2d 580, 588, 146 N.W.2d 459 (1966). Three requirements must be met for the emergency doctrine to apply:

First, the party seeking the benefits of the emergency doctrine must be free from negligence which contributed to the creation of the emergency. Second, the time element in which action is required must be short enough to preclude deliberate and intelligent choice of action. Third, the element of negligence being inquired into must concern management and control before the emergency doctrine can apply.

Gage v. Seal, 36 Wis.2d 661, 664, 154 N.W.2d 354 (1967) (quotingGeis v. Hirth, 32 Wis.2d 580, 586, 146 N.W.2d 459 (1966)).

¶ 23. The rationale underlying the emergency doctrine "is that a person faced with an emergency which his conduct did not create or help to create is not guilty of negligence in the methods he chose, or failed to choose, to avoid the threatened disaster if he is compelled to act instantly without time for reflection." Seif, 49 Wis.2d at 23 (citing Papacosta v. Papacosta, 2 Wis.2d 175, 85 N.W.2d 790 (1957)). Stated another way: "[t]he application of the emergency rule rests upon the psychological fact that the time which elapses between the creation of the danger and the impact is too short under the particular circumstances to allow an intelligent or deliberate choice of action in response to the realization of danger. . . ." Gage, 36 Wis.2d at 664 (quoting Cook v. Thomas, 25 Wis.2d 467, 471, 131 N.W.2d 299 (1964)).

¶ 24. Before discussing why the emergency doctrine can apply to a violation of Wis. Stat. § 346.46, we first note that the stop sign statute is a safety statute, the violation of which constitutes negligence per se. "A safety statute is a legislative enactment designed to protect a specified class of persons from a particular type of harm. Betchkal v. Willis, 127 Wis.2d 177, 184, 378 N.W.2d 684 (1985) (quoting Leahy v. Kenosha Memorial Hospital, 118 Wis.2d 441, 449, 348 N.W.2d 607 (Ct.App. 1984)). Wisconsin Stat. § 346.46 is a safety statute. See Wis JI-Civil 1325-Stop at Stop Signs, and 1325A-Stop at Stop Signs (Alternate) (the headings of both jury instructions refer to the stop sign statute as a safety statute).

¶ 25. The violation of this safety statute constitutes negligence per se. Negligence per se arises from the violation of a safety statute if three requirements are met: 1) the safety statute was designed to prevent the harm inflicted, 2) the person injured was in a protected class, and 3) the legislature has expressed its intent that the statutory section serve as a basis for the imposition of civil liability. Betchkal, 127 Wis.2d at 184 (citing Walker v. Bignell, 100 Wis.2d 256, 268-69, 301 N.W.2d 447, 454, 455 (1981). First, Wis. Stat. § 346.36(1) was designed to prevent collisions resulting from vehicles that do not stop and yield to traffic having the right-of-way. Second, the statute was created to protect highway users, not merely to regulate the flow of traffic. The protected class is "vehicles which have entered or are approaching the intersection upon a highway which is not controlled by an official stop sign or traffic signal." Wis. Stat. § 346.46(1). Totsky was within the class of persons to be protected because his vehicle was on an arterial highway that did not contain a stop sign. Finally, the legislature's intent that § 346.46 serve as a basis for civil liability is implied by the language of the statute itself. See Walker, 100 Wis.2d at 271 (stating that "requisite intent may be supplied by necessary implication from the language of the statute.") See also Leahy, 118 Wis.2d at 450 (recognizing that legislative intent to impose civil liability may be stated directly or by implication in a statute). Section 346.46(1)'s language "is such a clear expression of concern for the safety of highway users, committed so plainly to the responsibility" of the operators of vehicles approaching stop signs, that we conclude that the legislature intended to impose civil liability on those individuals who violate the statute. Cf. Walker, 100 Wis.2d at 271.

¶ 26. We agree with the court of appeals that the violation of Wis. Stat. § 346.46(1) constitutes negligence per se, and that such violation can be excused through application of the emergency doctrine. We agree with the court of appeals' analysis for several reasons.

¶ 27. First, the court of appeals correctly relied upon La Vallie for the proposition that when the emergency doctrine applies it excuses a violation of a safety statute, thus precluding a finding of negligence. In La Vallie, the defendant's car skidded into another car after it hit a patch of snow and ice on the highway, but "[t]he jury absolved the plaintiff of negligence." 17 Wis.2d at 525. This court found that the "jury was properly instructed on the emergency doctrine," even though the defendant's alleged violations pertained to two safety statutes. Id. at 527. In holding that the jury was properly instructed on the emergency doctrine, we stated that "the emergency doctrine would excuse any alleged violation of sec. 346.34(1) [proscribing a change of direct course upon a roadway], since the change of direct course occurred at a time when the La Vallie car was out of control through no fault of the driver." Id. This statement not only demonstrates that the emergency doctrine may apply in a negligence per se case, but also that management and control was at issue in La Vallie.

¶ 28. The Totskys argue that La Vallie does not control this issue. We find the Totskys' arguments unpersuasive. The Totskys attempt to distinguish La Vallie on the basis that La Vallie dealt with the issue of position on the highway, which they contend merely creates an inference of negligence. (Pet. Br. at 15) (citingGeis, 32 Wis.2d at 591). In contrast, they argue that the duty to stop at a stop sign is absolute. (Pet. Br. at 15) (citing Wis JI-Civil 1325). However, the Totskys misconstrue the language inGeis that they rely upon. In Geis, 32 Wis.2d at 591, we stated that a party's "position on the wrong side of the road created an inference of negligence unless it was shown that this was beyond her control." See also Kempfer v. Bois, 255 Wis. 312, 314, 38 N.W.2d 483 (1949), and Zeinemann v. Gasser, 251 Wis. 238, 243, 29 N.W.2d 49 (1947). While this inference of negligence may not exactly equate with negligence per se, the inference establishes a prima facie case of negligence, which cannot be rebutted without a showing of circumstances beyond a party's control; in other words, an emergency. As such, La Vallie is persuasive authority in this case. A valid distinction between a so-called inference of negligence and negligence per se cannot be drawn under these circumstances.

¶ 29. Second, we agree with the court of appeals that the Restatement (Second) of Torts permits the application of the emergency doctrine, even though a safety statute is involved. While we recognize that this issue is a matter of statutory interpretation, we find the Restatement (Second) of Torts § 288A persuasive because it demonstrates that emergency is a generally accepted excuse to negligence per se. The Restatement (Second) of Torts § 288A, Excused Violations, (1965) states:

(1) An excused violation of a legislative enactment or an administrative regulation is not negligence.

(2) Unless the enactment or regulation is construed not to permit such excuse, its violation is excused when

(a) the violation is reasonable because of the actor's incapacity;

(b) he neither knows nor should know of the occasion for compliance;

(c) he is unable after reasonable diligence or care to comply;

(d) he is confronted by an emergency not due to his own misconduct;

(e) compliance would involve a greater risk of harm to the actor or to others.

Restatement (Second) of Torts § 288A (1965). Section 288A applies to actions where there is a violation of a safety statute, because it specifically refers to "legislative enactment." Restatement (Second) § 288A(1). Comment b explains that if a person's action is excused, the person was not negligent in the first place: "[i]n many of the situations in which the conduct of the actor is excused, such conduct is simply not a violation of the statute, ordinance, or regulation, for any purpose." Restatement (Second) of Torts § 288A(1) cmt. b. See also Harper, James Gray, The Law of Torts, § 17.6 at 641 (2d ed. 1986) (stating that if an excuse applies to a violation of a safety statute and, thus, otherwise would be negligence per se, "it means that violation of a statutory standard is negligence per se in a civil case only in the absence of evidence tending to establish some excuse that the court will recognize.")

¶ 30. In particular, the Comment on Clause (d) accepts the use of the emergency doctrine. It addresses how the emergency doctrine applies to a violation of a statute resulting in negligence per se. It states that "[a]s in other cases of negligence . . ., the violation of an enactment or regulation will ordinarily be excused when the actor is confronted by an emergency which is not caused by his [or her] own misconduct." Restatement (Second) of Torts § 288A cmt. on clause (d) (1965). We find in this comment an express acknowledgment of the emergency doctrine's use in regard to a violation of a statute resulting in negligence per se.

¶ 31. Finally, other leading authorities in tort law recognize the applicability of the emergency doctrine to a statute involving negligence per se. Prosser and Keeton note that violation of a statute in which no excuse is permitted really is strict liability. Prosser Keeton, The Law of Torts, § 36 at 227 (5th ed. 1984). Harper, James, and Gray recognize the meritorious objections to the "Draconian" nature of negligence per se. Harper, James Gray, The Law of Torts, § 17.6, 626 (2d ed. 1986). They point out that most jurisdictions temper negligence per se by allowing some consideration of excuse, such as emergency, or lack of control. Id. at 637-38. While this case is not based on policy considerations, the observations these authorities make are valid. We agree that negligence per se, by itself, is a draconian measure that can lead to unduly harsh and unfair results, particularly when a statute does not even call for civil liability. The emergency doctrine balances the obvious intended benefits of the safety statutes, with the desire not to punish an individual whose violation of a safety statute was due to no fault of his or her own.

¶ 32. Since we are faced with an issue of statutory interpretation, it is necessary for us to construe the language in Wis. Stat. § 346.46. We interpret the statute's language to support the applicability of the emergency doctrine as an excuse for the following reasons. The emergency doctrine may apply even though the statute uses mandatory language such as "shall." Wisconsin Stat. § 346.05, which also uses mandatory language, has been construed to permit the emergency doctrine's applicability.Geis, 32 Wis.2d at 591.

¶ 33. Although the statute's language is mandatory, it already contains two exceptions. These two exceptions indicate that the statute is not immutable. Again, we look to § 346.05 as an example. In that statute, several exceptions have been listed. Even though those exceptions were already listed in the statute, this court permitted the use of the emergency doctrine. La Vallie, 17 Wis.2d at 527. In sum, the language of Wis. Stat. § 346.46 supports our conclusion that the emergency doctrine may apply as an excuse.

¶ 34. We now examine the applicability of the emergency doctrine in this case. The emergency doctrine can apply to the violation of a safety statute, excusing what otherwise would be negligence per se, but only in situations where the three required tests of emergency are met. At issue in this case is the third test: whether the element of negligence inquired into concerns management and control. Precisely at issue is to what extent must the negligence concern management and control for the emergency doctrine to apply. We hold that management and control must be involved in the negligence inquiry, but it does not have to be the only standard of care at issue in a case. In other words, the emergency doctrine can absolve negligence as to management and control, even if the total negligence inquiry involves more standards of care than just management and control. LaVallie, 17 Wis.2d at 527 (stating that if a violation of a safety statute is caused by a loss of management and control, without fault on the part of the driver, then the emergency doctrine can apply).

¶ 35. First, it is important to define what exactly is meant by "management and control." Management and control relates to a person's manner of driving. Schmit v. Sekach, 29 Wis.2d 281, 289, 139 N.W.2d 88 (1965). The emergency instruction states that if a "driver is compelled to act instantly to avoid collision, the driver is not negligent if he or she makes such a choice of action or inaction as an ordinarily prudent person might make if placed in the same position." Wis JI-Civil 1105A, Management and Control-Emergency. The instruction pertaining to management and control further explains that "[a] driver must exercise ordinary care to keep his or her vehicle under proper management and control so that when danger appears, the driver may stop the vehicle, reduce speed, change course, or take other proper means to avoid injury or damage." Wis JI-Civil 1105, Management and Control. Management and control, therefore, is the choice of action or inaction that a person makes regarding his or her vehicle. Schmit, 29 Wis.2d at 289. See also Edeler v. O'Brien, 38 Wis.2d 691, 699, 158 N.W.2d 301 (1968).

¶ 36. A driver has three duties in regard to a stop sign: a driver must stop, then look, and then yield to traffic that has the right-of-way. Sailing v. Wallestad, 32 Wis.2d 435, 441, 145 N.W.2d 725 (1966) (quoting Schlueter v. Grady, 20 Wis.2d 546, 553-55, 123 N.W.2d 458 (1963)). Management and control is involved in the duties of both stopping and yielding. Wisconsin Jury Instruction-Civil 1105, which the jury considered, specifically refers to stopping as a proper means to avoid injury or damage. This court has also determined that applying brakes to a vehicle, which is integral to the ability to stop, is part of proper management. Simon v. Van de Hey, 269 Wis. 50, 57, 68 N.W.2d 529 (1955). As such, stopping is a method by which a driver can manage and control a vehicle.

¶ 37. Management and control is similarly involved in the duty to yield. Sailing additionally discussed the involvement of management and control in the duty to yield. In that case, the defendant failed to yield at a yield sign and hit a vehicle travelling on the intersecting arterial highway. Sailing, 32 Wis.2d at 436-37. This court stated that the degree of control required at a yield sign is less than at a stop sign. Id. at 442. By this statement, the court indicated that control to some extent is involved in the duty to yield. Even so, the court did ultimately state that it was proper for the circuit court not to instruct on management and control since the "evidence did not reveal sufficient reaction time available for there to be an issue of management and control."Id. at 445.

¶ 38. Management and control is not involved, however, in the duty of lookout. See Tombal v. Farmers Ins. Exchange, 62 Wis.2d 64, 71, 214 N.W.2d 291 (1974) (wherein the court stated that "Mrs. Tombal did make an efficient lookout and that she was not negligent as to speed and, further, that she was excused from possible negligence as to management and control by virtue of the emergency doctrine.") Even though obeying a stop sign includes more duties than those involving management and control, the emergency doctrine can still apply to the duties that do involve management and control. For instance, in Tombal, this court applied the emergency doctrine to management and control, but not lookout or speed, in regard to "[the] statutory duty to use caution when entering an intersection against a flashing yellow traffic control light." Id. Similarly, in Lievrouw v. Roth, 157 Wis.2d 332, 352-53, 459 N.W.2d 850 (1990), the court of appeals found that the emergency doctrine was correctly applied in a case in which both speed and management and control were at issue. The court specifically rejected the defendants' argument that because speed was at issue in addition to management and control, the emergency doctrine could not apply at all. Id. at 353. In its statement, "a driver may fail to exercise ordinary care with respect to both speed and management and control," the court implied that even though additional duties may be at issue in a case, if management and control is involved, the emergency doctrine could apply to the management and control portion of the negligence inquiry. Id. Therefore, if management and control is at issue in a case, the emergency doctrine may apply, even if other duties are also at issue. Of course, the emergency doctrine can only apply to the management and control portion of the negligence inquiry. Wis JI-Civil 1105A (stating that the "emergency rule is to be considered by [a juror] only with respect to [a juror's] consideration of negligence as to management and control.")

¶ 39. Since management and control is involved in at least two of the duties pertaining to obeying a stop sign, it is proper for a jury to be instructed on the emergency doctrine, if the other two requirements for application of the doctrine are met. In this case, both of those requirements were satisfied.

¶ 40. First, Williams did not act negligently, thereby causing the emergency. The speed at which she was travelling before the skid, approximately 16-23 miles per hour, was under the 25 miles per hour speed limit, certainly a reasonable speed under the conditions observable by her. Moreover, the ice upon which Williams skidded was not observable because that part of the road merely looked wet to her, and to Totsky, not icy.

¶ 41. Second, whether Williams had time to take deliberate action was a question for the jury. If the time frame in which a person must act is too short for an individual to take deliberate action, then a court can determine that there was an emergency as a matter of law. Schumacher v. Klabunde, 19 Wis.2d 83, 88, 119 N.W.2d 457 (1963). If, however, the time frame "was such that the confronted driver did have time for considered action," then there is no emergency as a matter of law. Id. The "circumstances surrounding the accident and the driver's opportunity to respond to the danger must be considered" in determining whether an individual is entitled to the emergency doctrine as a matter of law, or whether the issue should proceed to the jury. Seif, 49 Wis.2d at 24.

¶ 42. In this case, it appears that the time frame was not so short as a matter of law to preclude deliberate action. However, the time frame was still short enough to submit the issue to the jury. Krenz testified that the bus travelled the 100 feet from the beginning of the skid to the intersection in approximately four to five seconds. Under the circumstances surrounding the accident, we conclude that the issue of her opportunity to respond and to take deliberate action was appropriately submitted to the jury.

¶ 43. In summary, it was proper for the jury to consider the question of Williams' negligence in light of the emergency doctrine. The jury could reasonably conclude that Williams did not create the emergency by any negligence of her own since the ice the bus skidded on was not observable and she traveled at a reasonable speed. Moreover, the time element could reasonably be found to be short enough to preclude her deliberate reaction, and the negligence alleged concerned, at least in part, management and control.

¶ 44. Wisconsin Stat. § 805.14(1) provides the standard for a challenge to the sufficiency of the evidence:

No motion challenging the sufficiency of the evidence as a matter of law to support a verdict, or an answer in a verdict, shall be granted unless the court is satisfied that, considering all credible evidence and reasonable inferences therefrom in the light most favorable to the party against whom the motion is made, there is no credible evidence to sustain a finding in favor of such party.

A circuit court should only grant a motion for a directed verdict against a party with extreme caution. To grant such a motion, both a circuit court and an appellate court, including this court, must view the evidence in a manner most favorable to the party against whom the directed verdict is taken. Tombal, 62 Wis.2d at 68-69 (citations omitted). A motion for a directed verdict should only be granted if the "`court is satisfied that, considering all credible evidence in the light most favorable to the party against whom the motion is made, there is no credible evidence to sustain a finding in favor of such a party.'" Weiss v. United Fire Cas. Co., 197 Wis.2d 365, 388, 541 N.W.2d 753 (1995) (quoting § 805.14(1)). "If there is any evidence to sustain a defense or a cause of action, the case must be submitted to the jury." Tombal, 62 Wis.2d at 68 (citing Kielich v. Whittaker, 183 Wis. 470, 198 N.W. 270 (1924)).

¶ 45. Viewing the evidence in the light most favorable to Williams, we conclude that credible evidence supported the application of the emergency doctrine, and it was proper to instruct the jury about the doctrine. As such, the circuit court erred in directing the verdict in favor of the Totskys, since the circuit court proceeded on an erroneous view of the law in regard to the emergency doctrine and its applicability in this case.

¶ 46. The circuit court also erred in conditionally ordering a new trial. Wis. Stat. § 805.15(1) sets forth the grounds for granting a motion for a new trial. It states that a circuit court may set aside a verdict and grant a new trial when there are "errors in the trial, or because the verdict is contrary to law or to the weight of evidence, or because of excessive or inadequate damages, or because of newly-discovered evidence, or in the interests of justice." § 805.15(1). It is true that "where the trial court has awarded a new trial in the interest of justice, this court will affirm unless there is a clear showing of abuse of discretion." Bartell v. Luedtke, 52 Wis.2d 372, 377, 190 N.W.2d 145 (1971). Moreover, we have recognized that

the supreme court usually defers to the trial court's decision because of the trial court's opportunity to observe the trial and evaluate the evidence, and the order is highly discretionary. If one ground relied upon by the trial court in granting a new trial in the interest of justice is correct, this is sufficient to affirm the order of the trial court.

Id. (quoting Hillstead v. Shaw, 34 Wis.2d 643, 648, 150 N.W.2d 313 (1967)). However, in this case, we conclude that there was clearly an erroneous exercise of discretion by the circuit court in conditionally ordering a new trial. As the court of appeals stated, the circuit court erroneously exercised its discretion because it erred in its finding that the emergency doctrine never applies to a violation of a safety statute resulting in negligence per se. As we have determined, the emergency doctrine can apply to a violation of Wis. Stat. § 346.46(1), and therefore, the circuit court erred as a matter of law.

¶ 47. We also agree with the court of appeals that the circuit court erred when it granted a new trial on the basis of Williams' speed on icy roads. This finding was in error, the court of appeals stated, because a reasonable jury could have found, according to credible evidence that Williams' speed was not excessive. Therefore, she was not negligent as a matter of law. We agree with the court of appeals' conclusion.

¶ 48. We next address whether the subrogees have a duty to separately petition this court for review to preserve their subrogation claim. This issue presents a question of law, which we also review de novo. Schulte v. Frazin, 176 Wis.2d 622, 628, 500 N.W.2d 305 (1993). We hold that to preserve their claims, the subrogees must separately petition this court for review, unless they have entered into a stipulation to waive their rights to participate at trial and agree to be bound by the judgment.

¶ 49. "Subrogation rests upon the equitable principle that one, other than a volunteer, who pays for the wrong of another should be permitted to look to the wrongdoer to the extent it has paid and be subject to the defenses of the alleged wrongdoer."Employers Ins. Of Wausau v. Sheedy, 42 Wis.2d 161, 170, 166 N.W.2d 220 (1969). Subrogation does not create a new and independent cause of action. Wilmot v. Racine County, 136 Wis.2d 57, 63, 400 N.W.2d 917 (1987). However, the general rule is that a subrogation interest represents a distinct and separate part of a single cause of action. Id. at 61.See also Giese v. Montgomery Ward, Inc., 111 Wis.2d 392, 404, 331 N.W.2d 585 (1983); Wilmot, 136 Wis.2d at 64. This is even though a subrogee and a subrogor are subject to the same procedural rules. Sampson v. Logue, 184 Wis.2d 20, 29, 515 N.W.2d 917 (Ct.App. 1994). The subrogor's right to be made whole is superior to the right of the subrogee to recover on its separate part of a claim. Schulte, 176 Wis.2d at 637. Therefore, even if an insured and a tortfeasor settle a claim, the subrogated party's claim is left unsatisfied if no provision for the subrogated party is made as part of the settlement. Ritt v. Dental Care Assoc., 199 Wis.2d 48, 77, 543 N.W.2d 852 (Ct.App. 1995); Muchow v. Goding, 198 Wis.2d 609, 633, 544 N.W.2d 218 (Ct.App. 1995).

¶ 50. The subrogees' interests in this case are separate. Maxicare stated in its counterclaim and cross-claim that "any settlement between Plaintiffs and Defendants prior to verdict, will only extinguish the claim owned by the Plaintiff. Such settlement will not extinguish the separate, independent cause of action owned by Maxicare Health Insurance Company." (R. at 4:2) (emphasis added.) State Farm and the city of Milwaukee also attempted to preserve their separate subrogation interests. They both requested that in the event of a settlement between the Totskys and Riteway, a hearing would be held to determine whether State Farm and the city of Milwaukee could seek satisfaction of their claims.

¶ 51. Wisconsin Stat. § (Rule) 809.62 (1997-98), which governs the criteria for petitions for review, does not expressly exclude from its scope petitions for review by subrogated parties. The statute's inquiry centers on whether the decision below was adverse. Section 809.62 (stating that "a party may file . . . for review of an adverse decision. . . ."). In Bortz v. Merrimac Mut. Ins. Co., 92 Wis.2d 865, 869, 286 N.W.2d 16 (Ct.App. 1979), a subrogee's appeal was held not to be dependent on other parties' appeals. Moreover, Wis. Stat. § 803.03(2)(b) (1997-98) lists the options that a joined party may take in litigation. A party must exercise one of those statutory options to maintain the viability of a claim. Sampson 184 Wis.2d at 27; Anderson v. Garber, 160 Wis.2d 389, 399, 466 N.W.2d 221 (Ct.App. 1991). Thus, a subrogated party's (subrogee's) interests on appeal are not preserved as part of a subrogor's appeal.

¶ 52. Both the city of Milwaukee and Maxicare stipulated to waive their rights to participate at trial and agreed to be bound by the judgment. Because a waiver is binding unless a party withdraws the waiver upon timely motion, see Wis. Stat. § 803.03(2)(b) (1997-98), it appears that the city of Milwaukee and Maxicare's stipulations have survived on appeal, since they are still bound by their stipulation. Wyandotte Chemicals Corp. v. Royal Elec. Mfg. Co., Inc., 66 Wis.2d 577, 589, 225 N.W.2d 648 (1975) (stating that stipulations made at trial are binding on appeal). Riteway did expressly agree to the stipulations made before trial, and therefore, must be bound by its stipulations with the city of Milwaukee and Maxicare. However, no stipulation was entered between Riteway and State Farm. As such, State Farm's subrogated claim will be dismissed.

IV.

¶ 53. We conclude that the emergency doctrine applies to a violation of Wis. Stat. § 346.46(1) under the facts of this case, because a violation of Wis. Stat. § 346.46(1) is concerned with an issue of management and control. We further conclude that two of the subrogated parties in this case, the city of Milwaukee and Maxicare, are not required to file a separate petition for review to preserve their subrogated interests on appeal, because they stipulated to waive their rights to participate at trial and agreed to be bound by the judgment. However, State Farm, which did not enter into such a stipulation, was required to file a separate petition for review to preserve its subrogated interest on appeal, because its subrogated interest is separate from the Totskys' claim.

By the Court. — The decision of the court of appeals is affirmed.
