Ignition interlock devices – do they really work?


Posted on Dec 30, 2010

If you are caught driving under the influence of alcohol, one possible consequence of a DUI conviction is to end up with an ignition interlock device in your vehicle.  This is a device that requires you to blow into a tube, so your breath can be measured for the presence of alcohol before your car will start.  If there is alcohol detected in your breath, you will not be able to start your car and drive.

 

These devices are controversial, as in theory drivers can have another person blow into the device to start the car, making it less of a deterrent.  Offenders can also drive other people’s cars, without having to worry about dealing with such a device.

 

Studies do show that ignition interlock devices reduce the risk of offenders committing an alcohol-related traffic violation within a year after the device is installed.  However, as soon as the device is removed that benefit disappears.

 

Some offenders get around having a device installed by claiming that they do not drive, or they claim that they do not own a vehicle.  And, even when ignition interlock devices are required for all first-time DUI offenders – as they are in thirteen states (not Virginia) – they are not installed in the majority of cases.

 

The bottom line?  If used consistently they appear to help, but only on a temporary basis.
