In most jurisdictions, there are no restrictions on the year of the car on which an antique license plate can be used. However, some states may require that the antique license plate be used on a car that is at least a certain age, such as 25 or 50 years old. Additionally, some states may require that the antique license plate be used on a car that is of the same make and model as the year of the plate.
You should always check the specific regulations in your jurisdiction to determine whether you can use an antique license plate on your car.
