Vehicle registration plates of Washington (state)

1950 to present

In 1956, the United States, Canada and Mexico came to an agreement with the American Association of Motor Vehicle Administrators, the Automobile Manufacturers Association and the National Safety Council that standardized the size for license plates for vehicles (except those for motorcycles) at 6 inches (15 cm) in height by 12 inches (30 cm) in width, with standardized mounting holes. The first Washington license plate that complied with these standards was a modification of the 1954 plate, introduced in January 1956.
