What is an ignition interlocking device?

The Department of Motor Vehicles must require the person, if he or she is a subsequent offender and a resident of this State, to have installed on any motor vehicle the person drives, an ignition interlock device designed to prevent driving of the motor vehicle if the person has consumed alcoholic beverages. The length of time that an interlock device is required to be affixed to a motor vehicle following the completion of a period of license suspension imposed on the offender is two years for a second offense, three years for a third offense, and the remainder of the offender’s life for a fourth or subsequent offense.

The cost of the interlock device must be borne by the offender. This fee is not to exceed $360 per year for each year the person is required to drive a vehicle with an ignition interlock device. The interlock device must be inspected every 60 days to verify that the device is affixed to the motor vehicle and properly operating. This report will indicate the offender’s alcohol content at each attempt to start the vehicle during each 60-day period. If your alcohol level is too high, the vehicle will not start.

The offender shall be subject to an Interlock Device Point System managed by the Department of Probation, Parole and Pardon Services. An offender receiving a total of two points will have their length of time that the interlock device is required to be extended by two months. An offender receiving a total of three points will have their length of time that the interlock device is required to be extended by four months and must submit to a substance abuse assessment and successfully complete the plan of education and treatment, or both, as recommended by the certified substance abuse program. If you do not complete the recommended plan, or do not make progress toward completing the plan, the Department of Motor Vehicles must suspend your driver’s license until the plan is completed or progress is being made toward completing the plan. An offender receiving a total of four points shall have their license suspended for a period of one year and submit to a substance abuse assessment and successfully complete the plan of education and treatment, or both, as recommended by the certified substance abuse program. Completion of the plan is mandatory as a condition of reinstatement of the person’s driving privileges. The Department of Alcohol and Other Drug Abuse Services is responsible for notifying the Department of Motor Vehicles of an individual’s completion and compliance with education and treatment programs.
