Vehicle registration plates of Maryland

The U.S. state of Maryland first required its residents to register their vehicles and display license plates in 1910.

In 1956, the U.S. states and Canadian provinces came to an agreement with the Automobile Manufacturers Association that fixed the size for license plates for vehicles, except those for motorcycles, at six inches in height by twelve inches in width, with standardized mounting holes. The 1956 (expired March 31, 1957) issue was the first Maryland license plate that complied with these standards.
