bicycle proceeding in the same direction shall pass to the left at a
safe distance without interfering with the safe operation of the
overtaken vehicle or bicycle, subject to the limitations and
exceptions hereinafter stated.



21751.  On a two-lane highway, no vehicle shall be driven to the
left side of the center of the roadway in overtaking and passing
another vehicle proceeding in the same direction unless the left side
is clearly visible and free of oncoming traffic for a sufficient
distance ahead to permit such overtaking and passing to be completely
made without interfering with the safe operation of any vehicle
approaching from the opposite direction.



21752.  No vehicle shall be driven to the left side of the roadway
under the following conditions:
   (a) When approaching or upon the crest of a grade or a curve in
the highway where the driver's view is obstructed within such

approach from the opposite direction.

of any bridge, viaduct, or tunnel.
   (c) When approaching within 100 feet of or when traversing any

   This section shall not apply upon a one-way roadway.

an overtaken vehicle shall safely move to the right-hand side of the
highway in favor of the overtaking vehicle after an audible signal
or a momentary flash of headlights by the overtaking vehicle, and

slow moving vehicle from the duty to drive as closely as practicable
to the right hand edge of the roadway.

vehicle upon the right only under conditions permitting such movement
in safety.  In no event shall such movement be made by driving off

alighting have reached a place of safety, except as provided in
subdivision (b) hereof.
   (b) Where a safety zone has been establilshed or at an

caution for the safety of pedestrians.
   (c) Whenever any trolley coach or bus has stopped at a safety zone
to receive or discharge passengers, a vehicle may proceed past such

21757.  The driver of a vehicle shall not overtake and pass upon the

at rest, except:
   (a) When so directed by a police or traffic officer.
   (b) When upon a one-way street.

prevent compliance with this section.



21758.  In the event any vehicle is being operated on any grade
outside of a business or residence district at a speed of less than
20 miles per hour, no person operating any other motor vehicle shall

hour in excess of the speed of the overtaken vehicle, nor unless the
passing movement is completed within a total distance not greater
than one-quarter of a mile.

vehicle, any ridden animal, or any livestock shall exercise proper
control of his vehicle and shall reduce speed or stop as may appear
necessary or as may be signalled or otherwise requested by any person
driving, riding or in charge of the animal or livestock in order to
avoid frightening and to safeguard the animal or livestock and to
insure the safety of any person driving or riding the animal or in
