About Us

dui law sometimes prescribes ignition interlock

The Coalition of Ignition Interlock Manufacturers (CIIM) is composed of the nation’s leading companies that manufacture ignition interlock devices that prohibit impaired persons from starting their vehicle. Our shared goal is to provide state administrators, courts, and policy makers the tools necessary to keep our roads and highways safe from drunk drivers. We combine our member’s expertise, innovation, and experience to speak with one voice to reduce vehicle-related fatalities caused by alcohol-impaired drivers. Our voice brings credible, factual information on ignition interlock devices to public policy discussions.

There are currently 32 states that have first-offender laws that require the use of ignition interlocks. In these states, drunk driving offenders with interlock devices are required to upload data about their attempts to start their vehicles. Our manufacturers collect data and report to monitoring authorities who then adjudicate cases involving offenders.

Through this data, we are able to provide comprehensive statistics about how many intoxicated drivers have been stopped behind the wheel.
