Defines quot, driving while intoxicatedquot, and quot, driving under the influencequot. As driving or being in actual physical control of a motor vehicle while having a blood alcohol concentration of 0.08 or greater. Requires an ignition interlock device to: require a driver to provide a breath sample before the motor vehicle starts, and prevent a motor vehicle from starting if the alcohol concentration of the driver is above the legal limit. Authorizes reduction of the 180-day period to 90 days if: the driver's license is suspended for a minimum of 180 days as a result of the conviction, and the period for installation of an ignition interlock device begins after the last day of the suspension.
