The driver of a motor vehicle shall not drive within any sidewalk area except as a permanent or temporary driveway.

In making an otherwise lawful maneuver that requires traveling in or crossing a designated bicycle lane, the driver of a motor vehicle shall yield to any bicycle in the lane. As used in this section, the term “designated bicycle lane” shall mean a portion of the roadway or highway that  1 has been designated by the governing body having jurisdiction over such roadway or highway by striping with signing or striping with pavement markings for the preferential or exclusive use of bicycles.
