Unauthorized Use of a Motor Vehicle — often abbreviated UUMV and sometimes called "joyriding" — is charged when a person operates someone else's vehicle (or boat or aircraft) without the owner's consent. Unlike auto theft, it does not require an intent to permanently keep the vehicle, which is why it frequently arises from misunderstandings between family members, friends, or exes.
What the Law Covers
UUMV is defined in Texas Penal Code § 31.07. The State must prove that you intentionally or knowingly operated a vehicle without the effective consent of the owner.
Punishment Range
UUMV is a state jail felony, punishable by 180 days to 2 years in a state jail facility and a fine of up to $10,000.
How These Cases Are Defended
Consent is the central issue. A strong defense often shows that the person reasonably believed they had permission — for example, where a vehicle had been shared before, or where consent was given and later disputed. Other defenses include identity and the absence of the required knowing mental state.
