How Much Does an Ignition Interlock Device Cost?

An ignition interlock device, a shortened term for ignition interlocks or IID, became the answer to the usual problem of driving under the influence.

With an interlock device, the issue of drinking and driving can be addressed.  The interlock device is basically a Breathalyzer that is installed in your car’s ignition system – you breathe into the breathalyzer and your BAC (Breath Alcohol Content) is measured.  The vehicle will not start if the BAC of the driver is over a certain percentage.  The BAC limit differs from state to state, but it is commonly set at .02% to .04%.

If you were charged with a DUI, some states will have an ignition interlock law and will require you to install one as part of your court sentence.
