An ignition interlock device is a small breath analyzer that is installed to a vehicle’s dashboard and is electronically connected to the vehicle’s ignition. The device requires a driver to breathe into the unit for several seconds to measure a driver’s breath alcohol level and compare it with predetermined limits. If the driver’s breath alcohol concentration is over the authorized limit, the vehicle will not start. Additionally, the driver is required to provide breath samples periodically while the vehicle is in motion.
Under Missouri law, courts may order an individual who pleads guilty to or is convicted of a first-time DWI charge to install an ignition interlock device on all of his or her vehicles. For a second DWI charge, Missouri courts require the offender to install an ignition interlock in all vehicles owned by the offender. This means any court granting limited driving privileges to any individual who is found guilty of or pleads guilty to a second or subsequent DWI must require an ignition interlock device be installed in all vehicles operated by the person as a required condition of the limited driving privilege for a period of not less than one month.
