Using Ignition Interlock Systems

Tuesday, May 19th, 2009

A sophisticated system that tests the driver’s breath for alcohol is called Ignition Interlock System. It’s a device requiring the vehicle operator to blow through an alcohol sensor unit attached to the vehicle’s dashboard. And if the BAC is above the preset level (around .02 to .04 BAC), the car cannot be started.

Some alcohol safety interlocks do not only require one test to start the engine, but it also calls for the test every few minutes while the car is running. This is called a “running or rolling retest” and would prevent drunken drivers to use their friend’s breath in the test to start the car.

All DUI offenders can benefit from ignition interlock use. Their lives will remain undisrupted and they can still use their car – to run errands, pick up their children, go to work, etc. At the same time, installing this device will also remind them that their right to drive comes with a responsibility to be sober each time they want to control the wheel.

The use of an ignition interlock system is also required as provision of parole/probation. DUI offenders better ensure that they use this device properly when they get behind the wheel to avoid jail time.
