Road signs, signals and meanings by state

Start with shape and color, then look at the message. Regulatory signs give rules you must follow; warning signs call attention to a hazard or a changing road condition. Guide and service signs help you find a route or a destination.

Signals, pavement markings, and hand signals also communicate what drivers should do. Your state library includes the images selected for that handbook, so the mix can include diagrams as well as roadside signs.

After browsing, try the Roadwise sign quiz. It uses picture questions to check recognition and explains each answer. The public libraries below remain readable without opening a session or creating an account.
