A car registration lets a state know who owns a vehicle, and it helps keep track of all cars on its roads. Each state and country handles this differently, but a registration is typically a way for people to prove that they own the car and are responsible for driving it. This also lets a state collect information about all the vehicles in its territory, which can be useful for things like taxes and finding criminals.
Each state and country's requirements for registering a car vary slightly, but you can generally expect to submit some form of proof that you are the owner and driver of the vehicle, along with your name and address, and payment for any fees or taxes required to register the vehicle. You might also need to provide proof that the vehicle has passed a safety inspection and smog test.
In many cases, you will be able to register your vehicle online, though you may need to go in person to verify your identity and give the department or agency responsible for car registration any other documentation it requires. Make sure you have all the documents you need before you begin to avoid any delays or unforeseen issues.
