Idaho Code § 18-8010
Every person who is convicted, found guilty, pleads guilty or receives a withheld judgment for violating the provisions of this chapter shall be required to pay an additional fifteen dollars ($15.00) in addition to any other fine, penalty or costs the court may assess. Moneys received pursuant to this section shall be remitted to the county treasurer in the county where the person was adjudicated for deposit in the "court interlock device and electronic monitoring device fund," which is hereby created in each county. Moneys in this fund may be utilized for the purchase of ignition interlock devices and electronic monitoring devices required pursuant to sections 18-8002, 18-8002A, 18-8005, 18-8008 and 18-8008A, Idaho Code. Additionally, any moneys a court charges a defendant for using an ignition interlock device or electronic monitoring devices shall be placed in this fund. The court or a prosecuting attorney who establishes a diversion program pursuant to section 19-3509, Idaho Code, may also utilize moneys in this fund to assist an indigent defendant or indigent diversion participant to procure an ignition interlock device or electronic monitoring devices. The court may also utilize moneys in this fund for alcohol or drug abuse-related probation, treatment or prevention programs for adults or juveniles.
