BIKE LANE
California MUTCD, sign R3-17What does the BIKE LANE sign mean?
A lane for bicycles. Drive in it only to park, to enter or leave the road, or within 200 feet of a right turn (CVC 21209).
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”).
