Restricted Interlock License

According to the Texas Department of Public Safety, if a court convicts you of DUI, you may eventually receive a restricted interlock license. This license authorizes you to drive a car that is equipped with a certified ignition interlock device.

The Texas Department of Public Safety will not issue this license if:

  • Your current license has expired
  • A court has suspended your driver’s license
  • You have not yet paid the associated interlock device fees

Fees Associated with Ignition Interlock Devices

According to Texas Statutes, if a judge orders an individual to fit an interlock device on his or her car, it must be at the person’s own expense. If you are unable to afford the device, the court may impose a payment schedule. The term of this schedule must not exceed the period stipulated in the court’s order.

You may also have to pay for the device’s upkeep and monitoring. Failure to do so, or to meet your payment terms, may result in additional penalties.

How Does an Ignition Interlock Device Work?

In order to start a car with an ignition interlock device, the driver has to breathe into the device for a BAC measurement. The driver will have to do this again after 5 minutes to keep the engine running. These breath tests will continue over the course of your journey in intervals of about 30 minutes.

Where Can I Install an Ignition Interlock Device?

Only DPS-certified facilities can install court-ordered ignition interlock devices. These centers must be certified by the Regulatory Services Division of DPS.

There are several potential defenses to DUI charges. In fact, it may be possible that police did not have the right to pull you over in the first place. The right defense can help mitigate penalties or possibly convince the court to drop the charges.

No two cases are identical, which is why Dallas DWI lawyer John L. Corn tailors each client’s defense strategy to the unique facts of their case. To start planning your defense, call our office today at 214-528-4529.

  • John is the epitome of under promise and OVER deliver… I called Mr. Corn on a Sunday night after my arrest and Mr. Corn spent 45 minutes to an hour with me on the phone without asking for a dime. He was not pushy asking for my business and just told me to give him another call if I wanted him to represent me for my DWI. The result of my situation: DISMISSED. I would recommend Mr. Corn without question.
