Ignition Interlock law is a major victory for Mothers Against Drunk Driving

As a result of intense lobbying efforts from Mothers Against Drunk Driving, drivers in New York will now be safer on the roads. People convicted of DWI will now have an ignition interlock device placed in their vehicle before they can drive again. An ignition interlock device measures the alcohol content of a driver's breath and prevents the engine from starting if it detects a too-high level. The convicted drunk driver bears the expense of the interlock device.


Interlock systems are now harder to defeat.

Interlocks may be set for "running" retests, which require a driver to provide additional breath tests at regular intervals once they start driving. This prevents drivers from asking a sober friend to start the car, or from starting the car and then drinking while driving. A running retest failure is logged in the device's data recorder and provides an audible warning for the driver to stop the vehicle (pull over notice). It also initiates audible and visible warnings (e.g., flashing lights or honking horn) so other drivers, including the police, will notice the vehicle if the driver continues to drive.
