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

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

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

shall continue to yield the right-of-way to those vehicles until he
or she can proceed with reasonable safety.

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

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

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.



21810.  (a) The driver of a vehicle overtaking a transit bus shall
yield the right-of-way to the bus if all of the following conditions
are present:
   (1) The transit bus has entirely exited an active traffic lane to
board or deboard passengers at a designated bus stop, and is
attempting to reenter the lane from which it exited.
   (2) Directional signals on the transit bus are flashing to
indicate that the bus is preparing to merge with traffic.
   (3) The transit bus is equipped with a yield right-of-way sign on
the left rear of the bus.  The sign shall be both of the following:
   (A) Designed to warn a person operating a motor vehicle
approaching the rear of the bus that the person is required to yield
the right-of-way to the bus when the bus is entering traffic.
   (B) Illuminated by a flashing light when the bus is signaling in
preparation for entering a traffic lane after having stopped to
receive or discharge passengers.
   (b) Nothing in this section requires a transit agency to install
the yield right-of-way sign described in paragraph (3) of subdivision
(a).
   (c) This section does not relieve the driver of a transit bus from
the duty to drive the bus with due regard for the safety of all
persons and property.  Nothing in this section relieves the transit
agency from complying with the standard of care for its passengers
established by Section 2100 of the Civil Code.
   (d) The provisions of this section are applicable to the Santa
Cruz Metropolitan Transit District, the Orange County Transportation
Authority, the Alameda-Contra Costa Transit District, and the Santa
Clara County Transit District, if the governing board of the district
approves a resolution, after a public hearing on the issue,
requesting that this section be made applicable to it, and transmits
a copy of the resolution to the commissioner.
   (e) (1) Notwithstanding Section 7055.5 of the Government Code, on
or before December 31, 2002, the commissioner, after consultation
with the participating transit agencies, participating law
enforcement, and the advisory committee established pursuant to
paragraph (3) of subdivision (a) of Section 34501 of the Vehicle
Code, shall report to the Legislature on the effectiveness of the
right-of-way for transit vehicles established by this section,
including, but not limited to, any impact on the highway and local
road safety and the efficiency of transit operations.  The report
shall recommend whether or not the right-of-way established by this
section should be made permanent on a local basis, and whether it
would be effective if implemented on a statewide basis.
   (2) The commissioner, in consultation with the participating
transit agencies, the California Transit Association, the advisory
committee, and the participating local law enforcement agencies,
shall identify the information required for preparation of the report
required under paragraph (1).  This information may include, but
need not be limited to, all of the following:

local law enforcement agencies, transit agencies, and the California
Transit Association shall provide the commissioner with the
information by using that format and in compliance with that
schedule.
   (f) Each transit agency participating in the program shall
undertake a public education program to inform motorists of the
requirements imposed by this section.
   (g) The base fine for a violation of subdivision (a) is
thirty-five dollars ($35).
