Texas unauthorized use of a vehicle — Penal Code § 31.07

Texas unauthorized use of a vehicle is a criminal offense under Penal Code § 31.07. Base conduct is classified as a state jail felony; enhancements and aggravators can move the punishment range higher. Below: the controlling statute text, the full punishment range, common defense theories, and what to do if you have been charged in Collin, Dallas, Denton, or Tarrant County.

The controlling statute

Texas Penal Code § 31.07 — Unauthorized Use of a Vehicle (UUMV) — criminalizes operating someone else's motorboat, airplane, or motor-propelled vehicle without the owner's effective consent. The statute is sometimes called Texas's joyriding law because it does not require intent to permanently deprive the owner (which would be theft under § 31.03). Even temporary use without permission is a state jail felony, and the offense is frequently charged alongside or in lieu of theft when prosecutors cannot prove intent to keep the vehicle.

Classification & punishment range

Elements the State must prove

To convict on a Texas § 31.07 charge, the State must prove every element beyond a reasonable doubt:

1. Defendant intentionally or knowingly operated a motor-propelled vehicle, motorboat, or airplane
2. Without the effective consent of the owner
3. The vehicle was owned by another at the time of operation

Defense strategies

L and L Law Group, PLLC develops the following defense strategies on every Unauthorized Use of a Vehicle case:

• Mistaken belief of consent — § 8.02 mistake of fact about owner's permission
• Apparent authority — defendant reasonably relied on a person who appeared to control the vehicle
• Family-vehicle defense — implied consent within household relationships
• Necessity (§ 9.22) — emergency use to prevent imminent harm
• Misidentification of operator via DNA, fingerprints, or surveillance
• Insufficient proof of operation — being a passenger is not § 31.07 conduct

Enhancements & collateral consequences

Two prior state jail felony convictions can elevate the punishment range to a third-degree felony under § 12.425. Use of a stolen vehicle in the commission of another felony often draws stacked charges. When the vehicle is used to flee a separate offense, § 38.04 Evading Arrest with a Vehicle (also a state jail felony) is commonly added.
