On Behalf of | Aug 11, 2020 | Criminal Defense

All 50 states have tough laws on drunk driving, and all 50 states have ignition interlock requirements for offenders. Understanding Texas’s specific ignition interlock laws is important for your situation.

Not all DWI offenders need ignition interlock devices. According to the state of Texas, you must install an ignition interlock device if this is your second or subsequent offense, if you had a blood alcohol concentration of greater than .15 or if you are under the age of 21.

What is an ignition interlock device?

An ignition interlock device is essentially a breathalyzer that a third-party company installs in your vehicle. When you want to turn on your vehicle, you must breathe into the ignition interlock device. The device will then ensure that there is no alcohol on your breath. If there is, the car will not start.

Once the car is in motion, you will need to breathe into it occasionally to prove to the machine that you have not consumed alcohol since starting the car. You are responsible for all costs associated with installing and maintaining the ignition interlock device.

How long do I have to have an ignition interlock device?

The amount of time you must have an ignition interlock device installed in your car depends on your particular situation. If you must have an ignition interlock device as part of your probation, usually you will need to have it for at least half of the supervision period. If the courts require an ignition interlock device for bond, you will need it until the courts dispose of the case.
