What is DUI Ignition Interlock?

An ignition interlock device (IID) is an in-car breathalyzer device used to measure the amount of alcohol in the user’s breath. Installing one is a common requirement following a drunk driving offense such as a DUI because it prevents a user from starting a vehicle until a breath alcohol test with a favorable result is taken. The cost of installing this device is placed on the individual charged with the drunk driving offense.

The Washington State Patrol is the regulatory authority of ignition interlock devices, interlock service technicians, and interlock service centers throughout Washington State.

How does an ignition interlock work?

The purpose of an IID is to prevent a driver from starting and driving the vehicle if their blood alcohol concentration (BAC) is above the prescribed setpoint. If the individual’s breath test results are below the preset limit, the vehicle will start. The interlock device needs to be serviced and calibrated at an authorized service center regularly to ensure it can read BAC accurately. Washington state law requires individuals to service their IID once every 30 to 60 days.

How long does Washington State require drivers to install an interlock device for DUI?
