LEFT TURN YIELD ON GREEN
California MUTCD, sign R10-12What does the LEFT TURN YIELD ON GREEN sign mean?
On a green ball you may turn left, but yield to oncoming traffic first (CVC 21801).
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”).
