Traffic Signs In The United States - Regulatory Series Stock ...
src: thumbs.dreamstime.com

In the United States, road signs are, to a large extent, standardized by federal regulations, especially in the Manual on Uniform Traffic Control Equipment (MUTCD) and their counterparts Highway Standard Signs (SHS). There are no plans to adopt the Vienna Convention on Standards of Signs and Road Signs.

Twenty-three states together with the District of Columbia and Puerto Rico use manuals without change, 20 countries have adopted it in conjunction with additional volumes, and seven states have country versions in substantial compliance with MUTCD. There are also local versions used in big cities like New York City that use MUTCD compatible naming systems and/or state supplements. MUTCD and SHS establish seven general categories of signs for road and highway use (all signs of the national MUTCD, except noted).

Rules

Regulatory signs provide instructions to motorists, pedestrians, and cyclists. Signs such as stop, no parking, no turns, and results are considered as a rule sign. Some have special shapes, such as octaves for stop signs and X forms for railway crossings. Some signs can be localized, such as no parking, and some are only found in state and local jurisdictions as they are based on state or local laws, such as the New York City "Do Not Block the Box" sign. These signs are in the R series of signs on the MUTCD and are usually in the R series in most state supplements or MUTCD countries.
