What is an interlock system?

An interlock system, also referred to as a car breathalyzer or ignition interlock, is a device that is installed in your vehicle to prevent you from drinking and driving. By requiring you to submit breath samples, the car interlock system measures how much alcohol is in your system and allows you to operate your vehicle if the alcohol in your body is below a certain amount.

Do I need an interlock system?

If you have been convicted of drunk driving, you may be required by your state monitoring authority (court, DMV, probation officer, etc.) to install an ignition interlock system in your vehicle. For a simple overview of ignition interlock laws in your state, visit our state requirements page and enter the state you were convicted in.

If you have not been convicted of drunk driving, but you are concerned that the current habits of you or your loved ones may lead to one, visit our voluntary ignition interlock devices page and see how Intoxalock Ignition Interlock can help protect you and your family.
