Drunk driving is a serious threat on the road, as it increases the chances of motor vehicle crashes. Alcohol lowers your inhibitions, reaction time, and judgment, all of which are necessary to safely operate a vehicle. As such, the penalties for Driving While Intoxicated (DWI) are severe. For most drivers convicted of DWI, an ignition interlock device will be required to regain their driving privileges. Please continue reading to learn when installation of this device is mandatory in Texas and why connecting with a qualified Dallas DWI Lawyer is in your best interest. 

What is an Ignition Interlock Device?

An ignition interlock device (IID) is a device that is wired into a vehicle’s ignition system and requires a driver to perform a breathalyzer test before the vehicle starts. If the breathalyzer results are greater than the programmed blood alcohol concentration (BAC), the device will prevent the engine from being started. Essentially, this device is intended to prevent drivers from operating the vehicle if they have alcohol in their system.

It’s important to understand that while the vehicle is in operation, the IID will randomly request the driver to provide another breath sample to ensure their sobriety behind the wheel. If the driver continues to drive after being prompted to provide a breath sample, the device will sound an alarm. Drivers must pull over to the side of the road and provide the sample. If they fail a retest, the vehicle will remain on until the keys are removed from the ignition. However, drivers can get locked out if they miss a random test while the vehicle is running.

When is Installation Mandatory in Texas?

In Texas, installing an ignition interlock device is required under certain circumstances. For instance, those charged with a first offense DWI may be required to install one of these devices in all the vehicles they operate. In some cases, the judge may not make this a requirement, but if the driver wishes to obtain an occupational license while their license is suspended, they can petition for the installation of this device. However, Texas law requires the mandatory installation of an IID if the driver has a BAC of .15% or higher and for all repeat offenders as a condition of their probation. Installation is also mandatory for a second DWI, regardless of their BAC.
