Vehicle registration plates of New Hampshire
The U.S. state of New Hampshire first required its residents to register their motor vehicles and display license plates in 1905. Plates are currently issued by the Division of Motor Vehicles of the New Hampshire Department of Safety.
Passenger baseplates
1905 to 1972
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 at in height by in width, with standardized mounting holes. The 1955 issue was the first New Hampshire license plate that complied with these standards.| Image | Dates issued | Design | Slogan | Serial format | Serials issued | Notes |

1973 to present
In 1977, the U.S. Supreme Court ruled that vehicle owners may cover up the mottos that a state places on its license plates. The case began in 1974 when George Maynard, a Jehovah's Witness from Claremont, New Hampshire, and his wife taped over the "Live Free or Die" motto on their plates. Maynard, who argued that the motto violated his religious beliefs, subsequently spent 15 days in jail for refusing to pay the $75 fine imposed for covering up the motto. Justice Burger stated, "The First Amendment protects the right of individuals to hold a point of view different from the majority and to refuse to foster, in the way New Hampshire commands, an idea they find morally objectionable."| Image | Dates issued | Design | Slogan | Serial format | Serials issued | Notes |
