State Ignition Interlock Laws
Updated June 2014
Below is information on state ignition interlock laws. All 50 states have some sort of ignition interlock law. Fifteen states—Alaska, Arizona, Arkansas, Connecticut, Hawaii, Kansas, Louisiana, Nebraska, New Mexico, New York, Oregon, Tennessee, Utah, Virginia, and Washington—have mandatory ignition interlock provisions for all offenses. Illinois and Colorado’s laws are not mandatory for a first conviction, but there are strong incentives to install an interlock device on the first conviction. In December 2013, the National Highway Traffic Safety Administrations released model guidelines for states encouraging them to adopt ignition interlock for first-time convicted drunk drivers and establish a minimum length of time in which offenders must use the interlocks.The report also contains guidelines for program administration and for venders and service providers.
