A vehicle registry is an official database that records information about vehicles, including their ownership, registration status, and identification details. This system helps governments track vehicles on the road, ensuring they are properly registered and meet safety and environmental standards. When a person buys a vehicle, they must register it with the appropriate government agency, usually the Department of Motor Vehicles (DMV) in the United States. This process typically involves providing details like the vehicle's VIN (Vehicle Identification Number), make, model, and proof of ownership, along with paying any required fees.
