the alcoholic or drug content of that person's blood pursuant to
Section 23612, and, if so requested, the arresting officer shall have
the test performed.  A conviction of a violation of this section

dollars ($250).  Violations of this section are subject to Section
13202.5.



21201.  (a) No person shall operate a bicycle on a roadway unless it
is equipped with a brake which will enable the operator to make one
braked wheel skid on dry, level, clean pavement.
   (b) No person shall operate on the highway any bicycle equipped
with handlebars so raised that the operator must elevate his hands
above the level of his shoulders in order to grasp the normal

   (d) Every bicycle operated upon any highway during darkness shall
be equipped (1) with a lamp emitting a white light which, while the
bicycle is in motion, illuminates the highway in front of the
bicyclist and is visible from a distance of 300 feet in front and
from the sides of the bicycle; (2)  with a red reflector on the rear
which shall be visible from a distance of 500 feet to the rear when

center of the bicycle, and with a white or red reflector on each side
to the rear of the center of the bicycle, except that bicycles which
are equipped with reflectorized tires on the front and the rear need
not be equipped with these side reflectors.  Such reflectors and
reflectorized tires shall be of a type meeting requirements
established by the department.
   (e) A lamp or lamp combination, emitting a white light, attached
to the operator and visible from a distance of 300 feet in front and
from the sides of the bicycle, may be used in lieu of the lamp

applicable to bicycle reflectors, the provisions of that regulation
shall prevail over provisions of this code or requirements
established by the department pursuant to this code relative to
bicycle reflectors.

that make it unsafe to continue along the right-hand curb or edge,
subject to the provisions of Section 21656.  For purposes of this

bundle or article which prevents the operator from keeping at least
one hand upon the handlebars.



21206.  This chapter does not prevent local authorities, by
ordinance, from regulating the registration of bicycles and the
parking and operation of bicycles on pedestrian or bicycle
facilities, provided such regulation is not in conflict with the
provisions of this code.

bicycle path or trail, bikeway, bicycle lane established pursuant to
Section 21207, equestrian trail, or hiking or recreational trail,
unless it is within or adjacent to a roadway or unless the local
authority or the governing body of a public agency having
jurisdiction over such path or trail permits, by ordinance, such
operation.


21208.  (a) Whenever a bicycle lane has been established on a
roadway pursuant to Section 21207, any person operating a bicycle

private road or driveway.
   (3) When reasonably necessary to leave the bicycle lane to avoid
debris or other hazardous conditions.
   (4) When approaching a place where a right turn is authorized.
   (b) No person operating a bicycle shall leave a bicycle lane until
the movement can be made with reasonable safety and then only after
giving an appropriate signal in the manner provided in Chapter 6
(commencing with Section 22100) in the event that any vehicle may be
affected by the movement.

than is reasonable or prudent, having due regard for visibility,
traffic conditions, and the condition of the roadway surface of the
bicycle lane, and in a manner which does not endanger the safety of
bicyclists.



21210.  No person shall leave a bicycle lying on its side on any
sidewalk, or shall park a bicycle on a sidewalk in any other
position, so that there is not an adequate path for pedestrian
traffic.  Local authorities may, by ordinance or resolution, prohibit
bicycle parking in designated areas of the public highway, provided
that appropriate signs are erected.

impedes or blocks the normal and reasonable movement of any
bicyclist.
   (b) No person may place or park any bicycle, vehicle, or any other
object upon any bikeway or bicycle path or trail, as specified in
subdivision (a), which impedes or blocks the normal and reasonable
movement of any bicyclist unless the placement or parking is
necessary for safe operation or is otherwise in compliance with the
law.
   (c) This section does not apply to drivers or owners of utility or
public utility vehicles, as provided in Section 22512.
   (d) This section does not apply to owners or drivers of vehicles

simultaneously and the rear turn signal lamps at each side of the
vehicle are being flashed simultaneously.
   (f) This section does not apply to the driver or owner of a tow
vehicle while actually engaged in the towing of a vehicle if the
front turn signal lamps at each side of the vehicle are being flashed
simultaneously and the rear turn signal lamps at each side of the
vehicle are being flashed simultaneously.

towed by the bicycle.
   (b) Any helmet sold or offered for sale for use by operators and
passengers of bicycles, nonmotorized scooters, skateboards, or

to the applicable safety standards.
   (c) No person shall sell, or offer for sale, for use by an
operator or passenger of a bicycle, nonmotorized scooter, skateboard,
or in-line or roller skates any safety helmet which is not of a type
meeting requirements established by this section.
