26708. (a) (1) No person shall drive any motor vehicle with any
object or material placed, displayed, installed, affixed, or applied
upon the windshield or side or rear windows.
(2) No person shall drive any motor vehicle with any object or
material placed, displayed, installed, affixed, or applied in or upon
the vehicle which obstructs or reduces the driver's clear view
through the windshield or side windows.
(3) This subdivision applies to a person driving a motor vehicle
with the driver's clear vision through the windshield, or side or
rear windows, obstructed by snow or ice.
(b) This section does not apply to any of the following:
(1) Rearview mirrors.
(2) Adjustable nontransparent sunvisors which are mounted forward

materials which are displayed in a 5-inch square in the lower corner
of the windshield nearest the driver.

(7) Rear trunk lid handle or hinges.
(8) The rear window or windows, when the motor vehicle is equipped

highway through each mirror for a distance of at least 200 feet to
the rear of the vehicle.
(9) A clear, transparent lens affixed to the side window opposite
the driver on a vehicle greater than 80 inches in width and which
occupies an area not exceeding 50 square inches of the lowest corner
toward the rear of that window and which provides the driver with a
wide-angle view through the lens.
(10) Sun screening devices meeting the requirements of Section
26708.2 installed on the side windows on either side of the vehicle's

physician and surgeon certifying that the person must be shaded from
the sun due to a medical condition, or has in his or her possession

installed, affixed, or applied to the topmost portion of the
windshield if the following conditions apply:

the undepressed driver's seat when measured from a point 5 inches in
front of the bottom of the backrest with the driver's seat in its
rearmost and lowermost position with the vehicle on a level surface.

(2) The material is not red or amber in color.
(3) There is no opaque lettering on the material and any other
lettering does not affect primary colors or distort vision through
the windshield.
(4) The material does not reflect sunlight or headlight glare into

of 70 percent and the abrasion resistance of AS-14 glazing, as
specified in that federal standard.
(3) The material is designed and manufactured to enhance the
ability of the existing window glass to block the sun's harmful
ultraviolet A rays.
(4) The driver has in his or her possession, or within the
