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 Georgia, the unauthorized use of a motor vehicle, often referred to as 'joyriding,' is a distinct criminal offense from theft. Under Georgia law, specifically O.C.G.A. § 16-8-5, it is illegal to use or operate any automobile, motorcycle, airplane, or other motor-propelled vehicle without the consent of the owner or the person authorized to give consent. The key element of this crime is the lack of consent from the owner, rather than the intent to permanently deprive the owner of the vehicle, which is a requirement for a theft charge. The penalties for unauthorized use of a vehicle can include fines, imprisonment, or both, depending on the circumstances of the offense and the defendant's criminal history. It is important for individuals charged with this offense to consult with an attorney to understand the specific implications of the charge and to receive legal representation.
