Residents in Texas who are convicted of a criminal charge for driving while intoxicated may face a range of penalties that could include the loss of driving privileges. Some people may have the opportunity to have their driving privileges restored but in order to do so they might have to install and use an ignition interlock device.
As explained by the Texas Department of Public Safety, approval for this requires that the driver ensure their license is in good standing. This may involve paying fees and also submitting proof of an SR-22 with the state. Once approved, it is the responsibility of the driver to arrange the installation of the device using a state-approved vendor. Payment for the installation must be made by the driver and ongoing maintenance costs are also to be paid for by the driver.
Using an ignition interlock device does allow people convicted of DWI offenses to regain the ability to drive sooner that they might otherwise have been allowed to do. However, it does involve some changes that they should know about. For example, one IID manufacturer known as Intoxalock explains that some commonly used substances such as toothpaste or mouthwash might have traces of alcohol in them and therefore will need to be avoided for some period of time before using the IID.
Even some food and beverages may interfere with accurate IID readings so people should avoid eating or drinking anything other than water at least 15 minutes before driving. Because random tests will be required while driving, people may also need to avoid eating or drinking anything but water when actively driving.
