All-way STOP
California MUTCD, sign R1-1 + R1-3PWhat does the All-way STOP sign mean?
Every road at this intersection has a STOP sign. Stop at the line; whoever stopped first goes first; at the same time, the driver on the left yields to the driver on the right (CVC 21800(c)).
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”).
