It is a criminal offense to use or operate a motor vehicle, boat, airplane, motorcycle, or other motor-propelled vehicle without the consent of the owner or other person authorized to give consent. This crime is generally known as (1) unauthorized use of a motor vehicle, (2) unauthorized use of a vehicle, or (3) joyriding.

The difference between this crime and the crime of theft is that the state does not have to prove a person charged with unauthorized use of a motor vehicle intended to keep the vehicle or permanently deprive the owner of the vehicle.

Laws regarding the unauthorized use of a motor vehicle vary from state to state and are generally found in a state’s statutes—often in the penal or criminal code or the vehicle code.

In Virginia, the unauthorized use of a motor vehicle, commonly referred to as 'joyriding,' is a criminal offense under Virginia Code § 18.2-102. This statute makes it illegal for any person to take, drive, or use a motor vehicle, aircraft, boat, or vessel without the consent of the owner. Unlike theft or grand larceny, the prosecution does not need to prove that the individual intended to permanently deprive the owner of the vehicle. The intent to temporarily use or operate the vehicle without permission is sufficient for this offense. Unauthorized use of a vehicle in Virginia is typically charged as a Class 6 felony, which can result in serious penalties including imprisonment, fines, and a criminal record. However, if the vehicle is valued at less than $1,000, it may be treated as a misdemeanor. It's important for individuals charged with this crime to seek the advice of an attorney to understand the specific charges and potential defenses.
