What is an ignition interlock device?

An ignition interlock device is a breath alcohol analyzer that is connected to a motor vehicle ignition.

If the alcohol concentration exceeds the startup set point on the interlock device, the motor vehicle engine will not start. 37 Texas Administrative Code 19.21.

When is the ignition interlock required?

On receipt of notice from the court that a person has been restricted to the use of a motor vehicle equipped with an ignition interlock device, the Texas Department of Public Safety (DPS) shall send notice that the driver license expires on the 30th day after the date of the notice. Texas Transportation Code Section 521.2465.

How long is the ignition interlock required?

The interlock is required until the Texas Department of Public Safety (DPS) receives a court order removing the restriction. Texas Transportation Code 521.2465.

Can an individual drive if the ignition interlock is required?

Yes, on application by the person and payment of the required fee, the Texas Department of Public Safety (DPS) shall issue a special restricted license that authorizes the person to operate a motor vehicle equipped with an ignition interlock device.
