STOP
California MUTCD, sign R1-1What does the STOP sign mean?
Come to a full stop at the white limit line (or before the crosswalk), then yield to traffic that is close enough to be a hazard (CVC 22450, 21802).
How regulatory signs work
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”).
