That is very rare in my experience. There are 3 levels of chain controls, and the most common is 2. The roads have to be pretty bad for them to require chains on all vehicles and at that point they are more likely to just close the road completely. I have been up there literally hundreds of times in the snow and even tho I chase storms for powder days I have never seen a level 3 chain control. But it can happen.
From the CALTRANS website:
Requirement One (R1): Chains, traction devices or snow tires are required on the drive axle of all vehicles except four wheel/ all wheel drive vehicles.
Requirement Two (R2): Chains or traction devices are required on all vehicles except four wheel/ all wheel drive vehicles with snow-tread tires on all four wheels.
(NOTE: Four wheel/all wheel drive vehicles must carry traction devices in chain control areas.)
Requirement Three (R3): Chains or traction devices are required on all vehicles, no exceptions.
SNOW-TREAD TIRES:
The California vehicle code section 558 defines a snow-tread tire as follows, " A 'Snow-tread tire' is a tire which has a relatively deep and aggressive tread pattern compared with conventional passenger tread pattern". Snow-tread tires can be identified by examining the sidewall of the tire where the letters MS, M/S, M+S or the words MUD AND SNOW have been stamped into the sidewall.
