What Is an Ignition Interlock Device, and When Is It Required?

An ignition interlock device is a breath alcohol analyzer that is connected to your vehicle ignition.  It requires you to provide a breath sample – free of alcohol – before the engine starts.  In order for your vehicle to start, you must blow a breath sample into the analyzer, which measures your alcohol concentration.  If your alcohol concentration exceeds the designation on the device, the engine will not start.  The company monitoring your IID will submit reports to the prosecutor and Court – so any positive blows can seriously impact your case and license.

In Texas, IIDs may be mandated for first-time offenders, as part of probation, or to obtain an Occupational License during any period of suspension.  According to the Code of Criminal Procedure, Texas Courts also require an IID, as a pretrial bond condition, if you’re charged with a second DWI or higher.  In these cases, you are typically ordered to install the IID within 30 days of your first court setting.

There may be ways to waive the requirement of an IID, depending on your situation and facts of your case.  With over 20 years of experience, Mr. Westbrook can help.  To schedule a free and confidential consultation regarding your DWI charge and ignition interlock devices, please call us today at 281-888-5581.
