28 US road signs and what they mean
The road signs you meet in Voorrah!’s Californian town, most with their code from the California MUTCD (the state’s manual of traffic signs), and what each means for you as a driver.
Regulatory signs
They give a rule you must obey. They are rectangular unless the manual names another shape (California MUTCD, section 2B.02); the STOP sign, for example, is an octagon (California Driver’s Handbook, “Laws and Rules of the Road”).
Warning signs
They warn you of a hazard or a change in the road ahead, so you can slow down in time. Most are yellow diamonds with a black legend and border (California MUTCD, section 2C.02).
School signs
They mark a school, its crosswalks and its speed limit. School warning signs have a fluorescent yellow-green background with a black legend and border (California MUTCD, section 7B.01).
