OPINION

WIENER, J.

Defendants William and Mary Eanes, insureds under a motor vehicle insurance policy issued by plaintiff Foremost Insurance Company, appeal from a judgment entered against them in a declaratory relief action filed by Foremost. They challenge the trial court's ruling that the policy in question could not possibly apply to indemnify the Eanes for their liability arising out of an accident which occurred while the subject vehicle — a motor home — was in Mexico. We conclude the trial court correctly interpreted the territorial limitation clause in the policy as precluding coverage, and affirm the judgment.

I

At the time of the accident, an insurance policy issued by Foremost insured the Eanes with respect to the motor home. (1) On page two of the policy provisions under a heading "Policy Period, Territory, Purposes of Use," the policy stated, "This policy applies only to accidents which occur and to direct and accidental losses to the automobile which are sustained during the policy period, while the automobile is within the United States of America, its territories or possessions, or Canada. . . ." (Italics added.)

The Eanes notified their insurance agent about the accident and, after Williams Eanes provided the company with a statement, Foremost paid the Eanes for the property damage which the motor home sustained. Later, Virgil and Judith Folands attempted to collect under the medical payments portion of the policy for the injuries they sustained in the accident. Relying on the territorial limitation clause in the policy, Foremost refused to pay. The Folands then filed suit against the Eanes relying on the statutory vehicle owner liability provisions of Vehicle Code section 17150 and on theories of negligent entrustment. The Eanes were never served in that action, apparently because the Folands were able to collect under the uninsured motorist provision of their own automobile policy issued by Fireman's Fund Insurance Company. As a result, Fireman's filed a subrogation action against the Eanes based on their payment to the Folands of an amount in excess of $28,000. When notified of the Fireman's suit, Foremost refused to defend and again cited the territorial limitation clause, this time in reference to the liability coverage of the policy. It then filed this action for declaratory relief to confirm its interpretation of the policy's inapplicability. The court below agreed, and entered judgment in favor of Foremost.

II

(2) The issue in this case focuses on whether the facts give rise to potential coverage under the Foremost policy, obligating Foremost to defend the Eanes against the Fireman's subrogation action. The Eanes proffer three different theories under which Foremost might be obligated to indemnify the Eanes for any liability resulting from the Fireman's suit.

A.

The Eanes first argue that the word "accident" in the territorial limitation clause (see ante, p. 569) is ambiguous and undefined within the context of the policy, which requires ascertainment of the reasonable expectations of the insured as to the extent of coverage. (See Insurance Co. of North America v. Sam Harris Constr. Co. (1978) 22 Cal.3d 409, 412-413 [ 149 Cal.Rptr. 292, 583 P.2d 1335].) They go on to point to two cases which have held it was reasonable for the insured to expect that "accident" referred not just to the injury-causing event (e.g., collision, explosion, etc.) but also included the negligent or wrongful act of the insured which constituted the legal cause of the injury. Thus, where the insured's negligent manufacture of drilling mud in Los Angeles caused the mud to burst into flame while being stored in a warehouse in Venezuela, the "accident" occurred in Los Angeles within the policy's "continental United States" limitation. ( Oil Base, Inc. v. Continental Cas. Co. (1969) 271 Cal.App.2d 378 [ 76 Cal.Rptr. 594].) And where a mechanic's negligence caused a vehicular collision five months later, the "accident" occurred during the servicing of the vehicle before the insurance policy expired. ( Sylla v. United States Fid. Guar. Co. (1976) 54 Cal.App.3d 895 [ 127 Cal.Rptr. 38].)

We have no quarrel with the basic proposition that use of the word "accident," if undefined in the policy, may create some degree of ambiguity in certain circumstances necessitating ascertainment of the insured's reasonable expectations. (See generally Gray v. Zurich Insurance Co. (1966) 65 Cal.2d 263, 269-270 [ 54 Cal.Rptr. 104, 419 P.2d 168].) But abstract ambiguity is not an authorization to ignore common sense. The insured's expectations of coverage must be reasonable. In order for this policy to provide coverage under the facts of this case, the "accident" must be viewed as having occurred at the Eanes' home in Orange County when they loaned their vehicle to the Hortons and the Folands. To argue that the loan of the vehicle constituted the "accident" in this case strains credulity. "Accident" suggests a negative unexpected occurrence. (See Geddes Smith, Inc. v. St. Paul Mercury Indemnity Co. (1959) 51 Cal.2d 558, 563-564.) While a manufacturing defect (see Oil Base, supra, 271 Cal.App.2d 378) or a negligent repair (see Sylla, supra, 54 Cal.App.3d 895) may conceivably fit within this rubric, the intentional loaning of a vehicle to friends does not. This is especially true if there is no owner negligence involved and liability is premised on the strict liability provisions of Vehicle Code section 17150 Under such circumstances, we find it impossible to view the totally expected and totally reasonable actions of the vehicle owner as constituting an "accident" within the meaning of the policy.

We also note that the Oil Base and Sylla decisions have been severely criticized. In Maples v. Aetna Cas. Surety Co. (1978) 83 Cal.App.3d 641, 647-650 [ 148 Cal.Rptr. 80], the court concerned itself with a negligently installed residential heater which caused a fire almost four years after the installer's insurance policy expired. That policy contained a provision limiting coverage to "accidents which occur during the policy period. . . ." After considering numerous California cases bearing on the issue, the court concluded as follows:

"Review of [the] seemingly unbroken line of authority finding that the term `accident' unambiguously refers to the event causing damage, not the earlier event creating the potential for future injury, leads to the question of how the courts in Oil Base and Sylla were able to reach results contradicting this line of authority. Neither Oil Base nor Sylla acknowledges any of the above-cited California or out-of-state authorities, which strongly suggest, that they were not briefed or argued." The court then emphasized that the fact that the word "accident" may be ambiguous in some contexts does not make it ambiguous in all:

"The rule of Oil Base and Sylla is acceptable only if it can truly be said that a person buying insurance to cover `accidents' occurring during the term of the policy would reasonably conclude that the policy would apply to any damage or injury occurring in the future because of a negligent act during the policy period. The fact that there may be ambiguity in the question of whether a collision with two cars is one accident or two accidents [see Hyer v. Inter-Insurance Exchange etc. (1926) 77 Cal.App. 343 ( 246 P. 1055)], or the question of whether malicious prosecution is an accident [see Maxon v. Security Ins. Co. (1963) 214 Cal.App.2d 603 ( 29 Cal.Rptr. 586)], or whether damage done by a defective door is an accident [see Geddes Smith, Inc. v. St. Paul Mercury Indemnity Co., supra, 51 Cal.2d 558] does not mean that there is ambiguity in the question of whether the term `accident' means the negligent installation of a heater or the fire six years later attributed to the negligent installation, which is our case at bench. Accepted popular, as well as legal definition, would call the latter event the `accident.'"

We accordingly conclude that the policy's use of the word "accident" does not create an ambiguity in the context of the facts presented by this case. The Eanes could not reasonably have expected coverage from this policy for liability arising out of a vehicular collision in Mexico. (See generally California State Auto. Assn. Inter-Ins. Bureau v. Warwick (1976) 17 Cal.3d 190, 195 [ 130 Cal.Rptr. 520, 550 P.2d 1056].)

B.

The Eanes next contend that the exclusionary effect of the territorial limitation clause is not "phrased in clear and unmistakable language." ( California State Auto. Assn. Inter-Ins. Bureau v. Warwick, supra, 17 Cal.3d 190, 194; see also Samson v. Transamerica Ins. Co. (1981) 30 Cal.3d 220, 236 [ 178 Cal.Rptr. 343, 636 P.2d 32].) They argue that the size and type of print did not serve to alert the insured as to the limitations on coverage. (See Miller v. Elite Ins. Co. (1980) 100 Cal.App.3d 739, 752 [ 161 Cal.Rptr. 322].) We cannot agree. The title of the clause — "Policy Period, Territory, Purposes of Use" — was set off in bold face type and adequately indicated that the ensuing language would define the policy's territorial application. The first five words of the sentence — "This policy applies only to . . ." — clearly inform the insured that the clause is limiting coverage under the policy. We do not view the phrasing and/or physical layout of the clause as precluding its enforcement.

C.

The Eanes finally point to Foremost's payment of the property damage claim and initial indication it would defend the Eanes as constituting a waiver of any right Foremost might have to deny coverage under the policy. (See generally Scott v. Federal Life Ins. Co. (1962) 200 Cal.App.2d 384, 391 [ 19 Cal.Rptr. 258] .) As to the intended provision of a defense to the Folands' complaint, Foremost never in fact defended the Eanes since the complaint was never served, and in any case, Foremost's communication to the Eanes explicitly reserved all its rights to contest the policy's applicability. (See ante, fn. 5.)

Foremost defends its payment of the property damage claim as being required under a separate "loss payable" indorsement to the policy providing for payment to the loss payee despite any "act or neglect" by the owner. Foremost suggests that the "loss payable" provision was designed so that the Eanes' decision to lend the motor home to persons who planned to drive into Mexico could not deprive the bank-lender of its security on the loan. Regardless of whether the "loss payable" provision required payment for the property damage claim despite the territorial limitations clause, we think the waiver principle is simply inapplicable here. Foremost's explanation establishes that it did not intend to relinquish its rights, and given the reasonableness of its interpretation of the "loss payable" clause, Foremost's conduct was not "inconsistent with the intent to enforce the right[s]." ( Scott v. Federal Life Ins. Co., supra, 200 Cal.App.2d at p. 391.)
