What is a Breath Alcohol Ignition Interlock Device?

An ignition interlock device (or IID) is basically a breathalyzer that is installed into a vehicle for the purpose of preventing drunk driving. It requires the driver to submit a breath sample before being able to start the car and then requires periodic samples while driving to ensure that no alcohol has been consumed while the vehicle is in operation.

How Do I Know if I Need One?

The state of Missouri has minimum time requirements for all DWI offenders. Additional rules or obligations may be required of an offender depending on the specific county in which the offense occurred. Most DWI offenders in Missouri receive documentation specifying that they need to get an IID installed in their vehicle.

If a DWI offender does not get the ignition interlock device installed as required by the court or any other state authority, they could face jail time as a result.

How Much Will My Offense Cost?

Depending on the type of offense, the cost to satisfy the obligation to the state of Missouri can vary greatly.
