Austin, Texas Ignition Interlock Device

If you are convicted of a second or subsequent driving while intoxicated (DWI) offense in Texas, you may face a number of increased penalties. In addition to jail time, a license suspension, and hefty fines, the court can also order you to install an ignition interlock device into your vehicle as a condition of your license reinstatement. The purpose of this device is to keep individuals from operating a vehicle while intoxicated again.

Ignition Interlock Device

The ignition interlock is a small device that is mounted on the dashboard and attached to the ignition. Similar to a handheld breathalyzer, this unit measures a sample of your breath to estimate your blood alcohol content (BAC). If you are over a pre-set limit (typically .02%), you will be unable to start your vehicle and the violation will be reported to the court or your probation officer.

To keep drivers from cheating the system or asking their friends to blow into the device to make the car start, you may be required to take a rolling retest after you have been driving. The system will give you time to pull over and take the test; however, if you fail to take the test or your BAC is over the pre-set limit, the vehicle’s horn will start honking and the lights will begin flashing until the vehicle is turned off.

There are several costs associated with the ignition interlock device penalty, which includes installation, maintenance, and monthly rental fees. All of these expenses must come out of your pocket, having a noticeable impact on your bank account.
