In the United States, road signs are, for the most part, standardized by federal regulations, most notably in the Manual on Uniform Traffic Control Devices (MUTCD) and its companion volume the Standard Highway Signs (SHS).

The 11th edition of the MUTCD was released on December 19, 2023.^[1] The effective date, 30 days after publication, of the MUTCD was January 18, 2024. States have two years after the effective date to do one of the following options: adopt the revised MUTCD, adopt the revised MUTCD with a state supplement, or adopt a state-specific MUTCD.^[2]

Eighteen states use the manual without alterations; 22 states, the District of Columbia, and Puerto Rico have adopted it in conjunction with a supplemental volume; and ten states have a state version in substantial conformance to the MUTCD.^[3] The MUTCD and SHS establish seven categories of signs for road and highway use, as follows:^[4] (The list does not cover all situations; the signage is from the national MUTCD unless specified):
