Vehicle registrations are official records that identify a vehicle and its owner. When someone buys a car, they must register it with their local government, usually through a department like the Department of Motor Vehicles (DMV). This process involves providing details such as the vehicle's make, model, and identification number, along with proof of ownership and payment of fees. Once registered, the vehicle receives a unique license plate and registration sticker, which must be displayed on the vehicle. This system helps authorities track vehicles for various purposes, including law enforcement, taxation, and ensuring compliance with safety and environmental regulations.
