Ignition Interlock Devices

Our DWI Attorneys Answer Your Questions

If you were arrested for DWI and you had a very high breath test result for blood alcohol content (BAC), or you had previous DWI convictions on your record, a judge may order you to consume no alcohol as a condition for allowing you out of jail on bond. To hold you accountable, the judge may order an ignition interlock device.

These devices are attached to the ignition system of your vehicle. It works by keeping your vehicle from starting until you breathe into the breathalyzer device attached to it to measure your BAC. If your blood alcohol is too high, the car will not start.

How Ignition Interlock Devices Can Help Your Case

While it may be embarrassing to have the ignition interlock device right there in the console of your car, to have to blow into it to start your car and to blow into it every 10 to 15 minutes for a rolling retest, it can actually be a big benefit. An ignition interlock device is one way to establish that you have met the terms of your release.

If you have an ignition interlock device on your car, you can prove that during the 6-12 months it took for your felony DWI case to get to court, you were, in fact, not drinking and driving. That can help you get a better sentence if you are ultimately convicted of a felony DWI.

Fighting a drunk driving charge in Texas isn't easy, but it's almost always worth it to protect your license and keep your criminal record clear. If you've been charged with DWI in the Dallas-Fort Worth area, contact a DWI attorney at Crain Lewis Brogdon, LLP. We do everything we can to save your driver's license, to fight the DWI charges in court, and to minimize the consequences of a conviction.

Don't Have a Car?

Because an ignition interlock-type device documents that you've been able to meet the terms of your bail, people who no longer have a car may want to have a similar device in their home. You blow into the device at set periods when you are in your house, establishing your sobriety.

Another option is a SCRAM bracelet (secured continuous remote ankle monitor) that gauges whether you have consumed any alcohol. This is a lot more cumbersome, so fewer people would choose this option. However, if this is the option that would work best for you, the court may respond to your request for this device.
