Currently, under provisions that will take effect on October 1, a court may order vehicle immobilization for up to 180 days for operating a vehicle while under the influence of liquor or a controlled substance (OUIL), operating a vehicle while impaired (OWI), or OUIL or OWI that causes a death or serious impairment of a bodily function. Under the bill, a court would be required to order vehicle immobilization for causing a death or serious impairment of a bodily function, and the 180-day maximum would apply to a person who had no prior conviction (i.e., any drunk driving offense, or negligent homicide, manslaughter, or murder resulting from the operation of a vehicle). The current immobilization period for a second violation of any drunk driving offense is not less than 24 days or more than 180 days. Under the bill, the minimum period would be 90 days and would apply to a conviction that occurred within seven years after a prior conviction. The current immobilization period for a third or subsequent violation is not less than six months or more than three years. Under the bill, the minimum period would be one year and would apply to a conviction within 10 years after two or more prior convictions.
