this lane is your lane - bikes only, please

California Vehicle Code is a little ambiguous on bike lane law — CVC 21211 prohibits parking or standing in bike paths (and maybe bike lanes, too, depending on how you read it), and double-parking in a bike lane is still double-parking (CVC 22500) and presumably just as illegal, but San Francisco Traffic Code gets explicit about the bikes-only limitation:

SFTC SEC. 38.N. PARKING IN BICYCLE LANES PROHIBITED; FINES.

(a) No person shall park any vehicle such that any portion of the vehicle is within a marked bicycle lane. No person shall block any portion of a marked bicycle lane with his or her vehicle on weekdays from the hours of 7:00 a.m. to 9:00 a.m. and from 4:00 p.m. to 6:00 p.m. Any person violating this Section shall be subject to a fine of $100. The Department of Parking and Traffic may install signs or otherwise alert motorists of this prohibition and the fine.

(b) This Section shall not apply to vehicles engaged in emergency services including, but not limited to, fire engines, police vehicles and ambulances.

(c) This Section shall not apply to public utility vehicles while such vehicles are operating, maintaining, or repairing facilities of the public utility or are being used in connection with providing public utility service.

(d) This Section shall not apply to commercial vehicles if an exemption is reasonably necessary to load or unload merchandise or passengers at any hours except between 7:00 a.m. and 9:00 a.m. and between 4:00 p.m. and 6:00 p.m.
