An ignition interlock is a fuel-cell device installed after market in a vehicle that tests the breath of the vehicle operator for presence of alcohol before it allows the vehicle to start. All U.S. jurisdictions have enacted legislation requiring or permitting the use of ignition interlocks. Many AAMVA member agencies are responsible for managing and implementing ignition interlock programs.
Ignition interlock program goals include reducing recidivism and enhancing compliance with laws related to driving under the influence of alcohol. These programs have proven to be effective at reducing alcohol-related violations and crashes as long as they are installed and used properly.
In 2023, AAMVA published the Ignition Interlock Program Best Practices, Edition 3 (IIPBP), to assist jurisdictions in the administration of ignition interlock programs. In addition to containing updates to the previous edition, Edition 3 also includes new content. Along with IIPBP, AAMVA refreshed the previously released Ignition Interlock Law Enforcement Training Video which instructs law enforcement officers on how to interact with vehicles equipped with an ignition interlock device as well as the operators of those vehicles.
AAMVA's Driving Under the Influence of Alcohol and/or Drugs Policy Position supports member use of the AAMVA Ignition Interlock Program Best Practice Guide and supports 24/7 programs to augment ignition interlock programs or to use in lieu of ignition interlocks when the nearest certified ignition interlock service provider is over 100 miles away.
