MUTCD

Manual on Uniform Traffic Control Devices (MUTCD)

You already might be able to recognize certain types of traffic signs, such as octagonal red stop sign and the yellow railroad crossing sign. Did you know that traffic signs can give drivers many different types of information? Some signs give instructions about what to do next, such as a rectangular white speed limit sign or a sign that tells drivers to yield to pedestrians at a crosswalk. Most types of yellow diamond-shaped signs are there to warn drivers about the dangers in the road up ahead. Other types of brown or green signs help drivers find their way.

The Manual on Uniform Traffic Control Devices, or MUTCD defines the standards used by road managers nationwide to install and maintain traffic control devices on all public streets, highways, bikeways, and private roads open to public traffic.The MUTCD, which has been administered by the FHWA since 1971, is a compilation of national standards for all traffic control devices, including road markings, highway signs, and traffic signals. It is updated periodically to accommodate the nation’s changing transportation needs and address new safety technologies, traffic control tools and traffic management techniques.
