Understanding California Chain Requirements
Chain Controls
Chain control areas are posted on mountain highways. When signs indicate “Chains Required,” you must stop and install chains. Failure to comply can result in fines.
Levels of Chain Requirements
R-1: Chains required on all vehicles except passenger cars/light trucks (<6,000 lbs) with snow tires on 2 drive wheels. Trailers must have chains on one axle.
R-2: Chains or traction devices required on all vehicles except 4WD/AWD with snow tires on all wheels. 4WD/AWD vehicles must still carry traction devices.
R-3: Chains required on all vehicles, no exceptions.
R-1 and R-2 are most common. Roads often close before R-3 conditions are imposed.
Installing Chains Guidelines
~1 mile to install chains after “Chains Required” signs
Drive slowly (25–30 mph) once chains are on
Stop in a safe area off the road to install chains
Chain installers are independent operators, not Caltrans employees
Remove chains only after passing “End of Chain Control” signs
How to Put Chains on Your Car
Purchase the right chains.
Lay chains out untangled with tensioners accessible.
Park in a safe, level spot.
Drape chains over tires, hooks outside.
Connect chains snugly, leaving room to adjust.
Adjust tightness; chains should lift slightly off the tire.
Repeat for other tires.
Drive slowly, avoiding sudden acceleration/braking, <30 mph.
Remove chains safely after passing “End of Chain Control” signs.
Final Tips
Winter travel in Yosemite is stunning but unpredictable. Carry chains, plan extra travel time from Mariposa, and check conditions daily for a safe, stress-free adventure.
