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 Connecticut, the unauthorized use of a motor vehicle, commonly referred to as 'joyriding,' is a criminal offense under state law. This crime is distinct from theft or larceny of a vehicle in that the prosecution does not need to prove an intent to permanently deprive the owner of the vehicle. Instead, the focus is on the unauthorized use itself. Connecticut's statutes classify unauthorized use of a motor vehicle as a separate offense, which is typically addressed in the penal or criminal code. The specific legal consequences for joyriding can vary, but they generally include potential fines, imprisonment, or both, depending on the circumstances of the offense and the individual's criminal history. It is important for individuals charged with this crime to consult with an attorney to understand the specific charges and potential defenses that may be available to them under Connecticut law.
