People who have a drunk driving conviction will sometimes need to operate a motor vehicle. This isn’t possible for many people, but some may have the option of having an ignition interlock device installed on their vehicle.
In Texas, a person may obtain a restricted interlock license if their license hasn’t expired and is still valid. People who have a cancelled, suspended, or revoked license for any other reason aren’t eligible for a restricted interlock license. They must also pay reinstatement and restricted interlock license fees. A person who has this type of license can only drive a vehicle if it has an ignition interlock device installed.
How do ignition interlocks work?
Ignition interlock devices require the driver to submit a breath sample before the vehicle will start. They’re programmed with a blood alcohol concentration (BAC) limit. If the breath sample result is over that BAC, the vehicle won’t start. If the sample is lower than the limit, it will start. Drivers may also receive alerts that they must pull over and submit a sample while they’re driving.
The company that installs the device also maintains and calibrates the device at regular intervals. A record of the testing and results is sent to the appropriate court agency, so drivers must always ensure they’re not attempting to drive after they’ve consumed anything with alcohol. Interestingly, this includes using mouthwash if it contains alcohol, so it’s critical to use caution.
Anyone who’s facing drunk driving charges should ensure they understand their rights and options at each step of the case. This can help them to make decisions they feel are in their best interests.
