Section 27459 Of Article 4. Tires From California Vehicle Code >> Division 12. >> Chapter 5. >> Article 4.
27459
. No person shall operate any motor vehicle, trailer or
semitrailer upon any portion of a highway without tire traction
devices when that portion of the highway is signed for the
requirement of tire traction devices. In any case where a passenger
vehicle or motortruck having an unladen weight of 6,000 pounds or
less may be required by the Department of Transportation or local
authorities to be equipped with tire traction devices, the devices
shall be placed on at least two drive wheels, or the department or
local authorities may provide, in the alternative, that the vehicle
may be equipped with snow-tread tires on at least two drive wheels
when the weather and surface conditions at the time are such that the
stopping, tractive, and cornering abilities of the snow-tread tires
are adequate. The snow-tread tires shall be of a type and design
manufactured for use on snow as a replacement for tire chains or tire
traction devices, shall be in good condition, and shall bear the
marking of M-S, M/S, or other marking indicating that the tire was
manufactured for use on snow, or, in the case of tires purchased
before January 1, 1987, shall either bear the markings or, in the
opinion of the inspecting officer, comply with the tread pattern
requirements of Section 558.
