Transportation: Bicycle Signals
21456.3. (a) An operator of a bicycle facing a green bicycle signal shall proceed straight through or turn right or left or make a U-turn unless a sign prohibits a U-turn. An operator of a bicycle, including one turning, shall yield the right-of-way to other traffic and to pedestrians lawfully within the intersection or an adjacent crosswalk.
(b) An operator of a bicycle facing a steady yellow bicycle signal is, by that signal, warned that the related green movement is ending or that a red indication will be shown immediately thereafter.
(c) Except as provided in subdivision (d), an operator of a bicycle facing a steady red bicycle signal shall stop at a marked limit line, but if none, before entering the crosswalk on the near side of the intersection, or, if none, then before entering the intersection, and shall remain stopped until an indication to proceed is shown.
(d) Except when a sign is in place prohibiting a turn, an operator of a bicycle, after stopping as required by subdivision (c), facing a steady red bicycle signal, may turn right, or turn left from a one-way street onto a one-way street. An operator of a bicycle making a turn shall yield the right-of-way to pedestrians lawfully within an adjacent crosswalk and to traffic lawfully using the intersection.
(e) A bicycle signal may be used only at those locations that meet geometric standards or traffic volume standards, or both, as adopted by the Department of Transportation.
