License plates are metal or plastic tags attached to vehicles, displaying a unique combination of letters and numbers. They serve as a form of identification for cars, trucks, and motorcycles, helping law enforcement and government agencies track vehicle ownership and registration. Each state or country has its own design and regulations regarding license plates. In many places, license plates are issued by the government and must be renewed periodically. Some regions allow personalized plates, where vehicle owners can choose specific combinations that may hold personal significance. License plates also often include information like the state or province of registration and expiration dates.
