Ignition Interlock

An Ignition Interlock is a device similar to a breathalyzer that measures the level of alcohol in a person's system before they get behind the wheel of a vehicle. An individual must blow into the device before he or she can start the car. If the amount of alcohol in his or her system exceeds a pre-programmed level, the interlock device temporarily locks the vehicle's ignition, and the engine cannot start until a valid breath sample is provided.

How does Ignition Interlock work?

The Ignition Interlock requires an individual to take an initial test when first getting into his or her vehicle. The first time alcohol is detected, the driver will be required to wait a few minutes before he or she can take the test again. If he or she fails subsequent tests, the driver is locked out for increasingly longer periods of time.

In addition to the initial test, some Ignition Interlock devices require random re-testing. A "rolling re-test" ensures that a driver does not consume alcohol after performing the initial test. In a re-test, the interlock device will beep while the vehicle is in motion, signaling the driver to deliver a breath sample. If alcohol is detected, the ignition interlock device will signal the driver to stop the car by blowing the horn and flashing the lights.

A majority of states use Ignition Interlock as an alternative to revoking driving privileges after an individual is convicted of a DUI. It allows these individuals to continue working, attending school, and participating in other routine activities.
