21800.  (a) The driver of a vehicle approaching an intersection
shall yield the right-of-way to any vehicle which has entered the

   (b) (1) When two vehicles enter an intersection from different
highways at the same time, the driver of the vehicle on the left
shall yield the right-of-way to the vehicle on his or her immediate
right, except that the driver of any vehicle on a terminating highway
shall yield the right-of-way to any vehicle on the intersecting
continuing highway.
    (2) For the purposes of this section, "terminating highway" means
a highway which intersects, but does not continue beyond the

shall yield the right-of-way to the vehicle on his or her immediate
right.
   (d) (1) The driver of any vehicle approaching an intersection
which has official traffic control signals that are inoperative shall

   (2) When two vehicles enter an intersection from different
highways at the same time, and the official traffic control signals
for the intersection are inoperative, the driver of the vehicle on
the left shall yield the right-of-way to the vehicle on his or her
immediate right, except that the driver of any vehicle on a
terminating highway shall yield the right-of-way to any vehicle on

21801.  (a) The driver of a vehicle intending to turn to the left or
to complete a U-turn  upon a highway, or to turn left into public or
private property, or an alley, shall yield the right-of-way to all
vehicles approaching from the opposite direction which are close
enough to constitute a hazard at any time during the turning
movement, and shall continue to yield the right-of-way to the
approaching vehicles until the left turn or U-turn can be made with
reasonable safety.
   (b) A driver having yielded as prescribed in subdivision (a), and
having given a signal when and as required by this code, may turn
left or complete a U-turn, and the drivers of vehicles approaching
the intersection or the entrance to the property or alley from the
opposite direction shall yield the right-of-way to the turning
vehicle.



21802.  (a) The driver of any vehicle approaching a stop sign at the
entrance to, or within, an intersection shall stop as required by
Section 22450.  The driver shall then yield the right-of-way to any
vehicles which have approached from another highway, or which are
approaching so closely as to constitute an immediate hazard, and
shall continue to yield the right-of-way to those vehicles until he
or she can proceed with reasonable safety.
   (b) A driver having yielded as prescribed in subdivision (a) may
proceed to enter the intersection, and the drivers of all other
approaching vehicles shall yield the right-of-way to the vehicle
entering or crossing the intersection.
   (c) This section does not apply where stop signs are erected upon
all approaches to an intersection.


21803.  (a) The driver of any vehicle approaching any intersection
which is controlled by a yield right-of-way sign shall, upon arriving
at the sign, yield the right-of-way to any vehicles which have
entered the intersection, or which are approaching on the
intersecting highway close enough to constitute an immediate hazard,
and shall continue to yield the right-of-way to those vehicles until
he or she can proceed with reasonable safety.
   (b) A driver having yielded as prescribed in subdivision (a) may
proceed to enter the intersection, and the drivers of all other

21804.  (a) The driver of any vehicle about to enter or cross a
highway from any public or private property, or from an alley, shall
yield the right-of-way to all traffic, as defined in Section 620,
approaching on the highway close enough to constitute an immediate
hazard, and shall continue to yield the right-of-way to that traffic
until he or she can proceed with reasonable safety.
   (b) A driver having yielded as prescribed in subdivision (a) may
proceed to enter or cross the highway, and the drivers of all other
vehicles approaching on the highway shall yield the right-of-way to
the vehicle entering or crossing the intersection.




21805.  (a) The Department of Transportation, and local authorities
with respect to highways under their jurisdiction, may designate any
intersection of a highway as a bridle path or equestrian crossing by
erecting appropriate signs. The signs shall be erected on the highway
at or near the approach to the intersection, and shall be of a type
approved by the Department of Transportation.  The signs shall
indicate the crossing and any crossmarks, safety devices, or signals
the authorities deem necessary to safeguard vehicular and equestrian
traffic at the intersection.
   (b) The driver of any vehicle shall yield the right-of-way to any
horseback rider who is crossing the highway at any designated
equestrian crossing which is marked by signs as prescribed in
subdivision (a).

duty of using due care for his or her own safety.  No horseback
rider shall leave a curb or other place of safety and proceed
suddenly into the path of a vehicle which is close enough to
constitute an immediate hazard.



21806.  Upon the immediate approach of an authorized emergency
vehicle which is sounding a siren and which has at least one lighted
lamp exhibiting red light that is visible, under normal atmospheric
conditions, from a distance of 1,000 feet to the front of the
vehicle, the surrounding traffic shall, except as otherwise directed
by a traffic officer, do the following:
   (a) (1) Except as required under paragraph (2), the driver of
every other vehicle shall yield the right-of-way and shall
immediately drive to the right-hand edge or curb of the highway,
clear of any intersection, and thereupon shall stop and remain
stopped until the authorized emergency vehicle has passed.
   (2) A person driving a vehicle in an exclusive or preferential use
lane shall exit that lane immediately upon determining that the exit
can be accomplished with reasonable safety.
   (b) The operator of every street car shall immediately stop the
street car, clear of any intersection, and remain stopped until the
authorized emergency vehicle has passed.
   (c) All pedestrians upon the highway shall proceed to the nearest
curb or place of safety and remain there until the authorized
emergency vehicle has passed.



21807.  The provisions of Section 21806 shall not operate to relieve
the driver of an authorized emergency vehicle from the duty to drive
with due regard for the safety of all persons and property.
