Ignition interlock requirements in Texas
Texas can order a device three ways — as a bond condition, as part of an occupational license, or on a finding of good cause. The occupational-license route is where the SR-22 comes in: the petition is not complete without it.
We do not sell interlocks. We do not install, service, calibrate or lease them, we take nothing from anyone who does, and there is no approved-provider list on this site. The state that issued your order publishes the list of devices it certifies; that list is the authority and it is free.
Three doors to an interlock in Texas
Texas reaches the device from three different statutes, each with its own trigger. A driver can meet all three in one case.
As a condition of bond
Before any conviction, a magistrate “shall require on release” that a defendant charged with a subsequent intoxication offense under Penal Code sections 49.04, 49.05, 49.06 or 49.061 — or with an offense under 49.045, 49.07 or 49.08 — have a device installed on the vehicle they own or most regularly drive, and not drive anything without one. Installation is at the defendant's expense and must happen “before the 30th day after the date the defendant is released on bond.” The magistrate may decline only on a finding that a device would not serve what the article calls the “best interest of justice.” Where the magistrate names an agency to verify and monitor the device, the defendant pays that agency a monthly reimbursement fee set by the magistrate, starting when installation is verified.
Tex. Code Crim. Proc. art. 17.441 · 2025 Texas Statutes
A magistrate “shall require on release” that a defendant charged with a subsequent offense under Penal Code sections 49.04, 49.05, 49.06 or 49.061, or an offense under 49.045, 49.07 or 49.08, have a device installed and not drive without it — installed at the defendant's expense “before the 30th day after the date the defendant is released on bond,” unless the magistrate finds a device would not serve what the article calls the “best interest of justice.”
As a condition of an occupational license
The occupational driver's license is how a suspended Texas driver keeps driving for essential needs, and it is where the device is most often imposed. The judge “shall restrict the person to the operation of a motor vehicle equipped with an ignition interlock device” if the person is already under a device order — including a bond condition — or if the license was suspended after a conviction under Penal Code sections 49.04 to 49.08. The court may waive it if the device is not necessary for community safety and a waiver is in the interest of justice.
Tex. Transp. Code sec. 521.246 · 2025 Texas Statutes
The judge “shall restrict the person to the operation of a motor vehicle equipped with an ignition interlock device” if the person is already under such an order (including a bond condition) or the license was suspended after a conviction under Penal Code sections 49.04-49.08; the court may waive it under subsection (b-1). The device stays for the period of suspension unless good cause is shown. An employer-vehicle exception applies under subsection (e).
On a finding of good cause
In any other occupational-license case, the judge may still impose a device on a finding of good cause.
The SR-22 is part of the petition
Texas joins the device and the insurance filing in the same document. A petition for an occupational license must “provide evidence of the petitioner's financial responsibility in accordance with Chapter 601” — the chapter whose certificate is the Texas SR-22. No filing, no complete petition; no petition, no occupational license; and no occupational license, no lawful driving with or without a device.
Tex. Transp. Code sec. 521.2421(d)(3) · 2025 Texas Statutes
A petition must “provide evidence of the petitioner's financial responsibility in accordance with Chapter 601.”
The certificate certifies 30/60/25 — $30,000 per person / $60,000 per accident / $25,000 property damage. Its period runs on its own clock, described on the Texas SR-22 page, and does not end when the device comes off.
What the occupational license allows
The court's order spells out the hours, the reasons, the routes, whether a device is required, and any testing, counseling or supervision. It also caps driving time: “the person may not operate a motor vehicle for more than four hours in any 24-hour period,” unless the court allows up to 12 hours on a showing of necessity. The license lasts until the end of the suspension.
Tex. Transp. Code sec. 521.248(b) · 2025 Texas Statutes
The order specifies hours, reasons, routes, any device restriction, testing, counseling and supervision. “The person may not operate a motor vehicle for more than four hours in any 24-hour period,” unless the court allows up to 12 on a showing of necessity.
Supervision while you hold it
The court may also order the license holder supervised to check compliance with the order — by the local community supervision and corrections department, which carries a monthly fee set elsewhere in Texas law, or by a personal bond office, which may charge $25 to $60 a month. Supervision can continue to the end of the suspension, including any extension, and the court may end it early for good cause.
Tex. Transp. Code sec. 521.2462(a-3) · 2025 Texas Statutes
The court may order supervision of an occupational-license holder by the community supervision department (with a monthly fee under Government Code sec. 76.015) or by a personal bond office, which “may collect… a reasonable administrative fee” of between $25 and $60 for each month of supervision.
The restricted license card: 30 days and $10
Once the department is told a person has been restricted to a device-equipped vehicle, it notifies the person that their license expires on the 30th day after the notice. On application and payment of $10, the department issues a special restricted license that conspicuously says the holder may drive only a vehicle with a device. At the end of the suspension, or on a court order removing the restriction, an unrestricted license is issued.
Tex. Transp. Code sec. 521.2465(a) · 2025 Texas Statutes
On notice of a device restriction, the license expires on the 30th day after the notice; “on application by the person and payment of a fee of $10, the department shall issue a special restricted license.”
Paying for the device
The person obtains the device at their own expense unless the court finds that would not be in the interest of justice and records the finding. Where the person cannot pay, the court may set a payment schedule for a term not exceeding twice the period of the order. The device stays installed for the period of suspension unless the court finds good cause to remove it and that it is not needed for community safety.
Driving an employer's vehicle
The occupational-license section allows driving an employer-owned vehicle without a device in the course of employment, if the employer is not owned or controlled by the restricted person, the employer has been told of the restriction, and proof of that notice is kept with the vehicle.
What the vendor owes you
Texas sets minimum standards for interlock vendors by rule, and the statute lists what those standards must require: authorization to do business, approved devices only, liability insurance, installation within a reasonable time after a court order — and repair or replacement “not later than 48 hours after receiving notice of a complaint.” A device that fails is the vendor's problem on a clock.
Tex. Transp. Code sec. 521.2476(b)(6) · 2025 Texas Statutes
Department vendor standards require each vendor to be authorized, install only approved devices, carry liability insurance, install within a reasonable time after a court order, and “repair or replace a device not later than 48 hours after receiving notice of a complaint.”
What this page does not cover
Penal Code chapter 49's offense levels, community-supervision terms and administrative license revocation are in provisions this site has not read for this page. Device prices are set by vendors, not by statute.
