If you operate a vehicle without the owner’s consent, it’s considered joyriding in the State of Texas. But, it’s a less serious crime than grand theft auto, because the person plans to return the vehicle to the original owner. So if you “borrow” a car without asking, you can be charged with joyriding. According to Texas statutes, the official charge is listed as the “unauthorized use of a vehicle.” This is considered a state jail felony carrying 180 days to a maximum of 2 years in a Texas state prison. You could also face a $10,000 fine.
