Texas Authorizes One Kind of Checkpoint, and It Is Not Sobriety

The absence here is verifiable rather than assumed. An exact-phrase search of the full text of every Texas code on the Legislative Council's own statutes system returns zero results for "sobriety checkpoint" and zero for "roadblock." The word "checkpoint" appears in only six Texas codes, and the operative grant of authority sits in a single section: Government Code Section 411.0095, added by Acts 1993, 73rd Legislature, Chapter 497, and last amended in 1999.

That section shows exactly what a Texas statutory checkpoint scheme looks like when the Legislature builds one. Subsection (a) sets the purpose, preventing stolen vehicles, farm tractors or implements, construction equipment, aircraft or watercraft from entering Mexico. Subsection (b) imposes four cumulative conditions: the checkpoint must be within 250 yards of a federally designated crossing facility at or near the actual boundary between Texas and Mexico, on a public highway or street leading directly to an international border crossing, designed to stop only traffic bound for Mexico, and operated so as to stop only property that law enforcement has probable cause to believe is stolen and bound for Mexico. Subsection (d) requires DPS to write procedures that minimize the intrusion on the driver and keep the inquiries reasonably related to the checkpoint's purpose, and it forbids an officer at the checkpoint from directing a driver or passenger to leave the vehicle or move it off the roadway without reasonable suspicion or probable cause of an offense, though vehicles may be diverted to an adjacent location for safety. Nothing resembling that framework exists anywhere in Texas law for intoxicated driving.

What Texas does authorize is the individual stop. Transportation Code Section 521.025(a)(2) requires a driver to display a license on the demand of a magistrate, court officer, or peace officer, and Subsection (b) permits a peace officer to stop and detain a driver to determine whether the person holds a license. Transportation Code Section 600.002 adds one narrow identification duty within 250 feet of the Mexican border at a checkpoint authorized by Section 411.0095, requiring the driver to produce a driver's license and proof of compliance with Chapter 601, the financial responsibility chapter. Neither provision authorizes a suspicionless stop for intoxication anywhere else in the state.

The testing regime confirms that arrest, not a checkpoint, is the trigger. Transportation Code Section 724.011(a) deems a person to have consented to breath or blood testing only where the person "is arrested" for an intoxication offense. Section 724.012(a) allows a specimen to be taken where the person is arrested and the officer has reasonable grounds to believe the person was operating a motor vehicle while intoxicated. Section 724.012(a-1) makes a blood draw mandatory where the person refuses, was the operator in a collision the officer reasonably believes resulted from the offense, and the officer reasonably believes an individual has died, will die, or has suffered serious bodily injury. Section 724.012(b) adds mandatory testing where a passenger was injured and hospitalized, where the arrest is for intoxication assault or a related offense, or where the officer has reliable information about qualifying prior convictions.

Before asking for a specimen, Section 724.015(a) requires the officer to inform the driver orally and in writing of eight specific consequences, including that refusal may be admissible in a later prosecution, that refusal triggers an automatic license suspension of not less than 180 days whether or not the driver is prosecuted, that the officer may apply for a warrant, that a driver 21 or older who tests at or above the Chapter 49 limit faces an automatic suspension of not less than 90 days, that a driver under 21 with any detectable alcohol faces at least a 60-day suspension, and that a hearing must be demanded at the department's Austin headquarters within 15 days of receiving notice. If the driver consents, Section 724.015(b) requires the officer to ask the driver to sign a statement confirming the request, the warning, and the voluntary consent.

One Texas right applies specifically to intoxication stops. Article 2B.0154 of the Code of Criminal Procedure entitles an individual stopped or arrested on suspicion of an offense under Penal Code Section 49.04, 49.045, 49.07 or 49.08 to receive from the employing law enforcement agency a copy of any video containing footage of the stop, the arrest, the individual's conduct during any interaction with the officer including a field sobriety test, or a breath or blood specimen procedure. That article was added by the Code of Criminal Procedure recodification, Acts 2023, 88th Legislature, Chapter 765 (H.B. 4504), effective January 1, 2025.

04(a) as being intoxicated while operating a motor vehicle in a public place. A first offense is a Class B misdemeanor with a statutory minimum term of confinement of 72 hours, rising under Subsection (c) to a minimum of six days if the driver had an open container of alcohol in immediate possession. 15 or more, and Subsection (e) makes it a state jail felony if the driver was in a school crossing zone during the reduced-speed period. 015(a)(7) gives a 15-day window from receipt of the notice to demand a hearing in writing at the Department of Public Safety headquarters in Austin.

23(a), which excludes evidence obtained in violation of the constitution or laws of Texas or the United States and requires the jury to be instructed to disregard it where the evidence raises the issue.
