According to the National Highway Traffic Safety Administration, in 2016, almost 29 people in the United States die in alcohol-impaired vehicle crashes every day.
The International Council on Alcohol, Drugs and Traffic Safety maintains that interlocks, when combined with a comprehensive monitoring and service program, lead to a 40-95 percent reduction in the rate of repeat drunk driving offenses, as long as the device remains on the vehicle. NHTSA strongly supports the expansion of ignition interlocks as a proven technology that keeps drunk drivers from getting behind the wheel.
An ignition interlock is a breath-analyzing device that is wired to the vehicle's ignition and installed on the vehicle dashboard. Before the vehicle can be started, the driver first must exhale into the device. If the interlock detects alcohol on the breath, the engine will not start.
When Arizona law mandates use of an interlock following a period of driver license suspension/revocation, you must have one installed by an MVD-authorized company and provide proof of the installation.
MVD uses special forms and procedures to monitor drivers required to have the device installed. Your record will be marked so that law-enforcement officers will be aware of the interlock requirement if you are stopped. You may be issued a replacement driver license containing the words "Ignition Interlock" if this is not your first offense.
Please Note: Have your interlock device installed first and then reinstate your driver license. Both of these steps are required to establish a starting point for your required ignition interlock time frame. You can reinstate online or visit an MVD or Authorized Third Party office.
