Best winter car gear for Mountain & Ski-Trip Driving
Mountain driving in winter is where chain laws, steep grades, and sudden whiteouts meet cars that were prepared for a city. The rules are simple: chains or approved traction devices in the car, sized to your tires, and practiced once at home; winter tires if you make the trip often; and the assumption that a closure could keep you on the pass for hours. Everything else follows from those three.

Must-haves
Chains/socks sized to your tires, boards, blanket
- ▸Chain controls escalate in levels (roughly: chains on 2WD / chains on all but 4WD-with-snow-tires / chains on everything). Levels, signage, and enforcement vary by state and pass — check the DOT's road-conditions site before you leave.
- ▸Chains go on the drive axle (front for most FWD/AWD, rear for RWD — check your manual), at a pull-out, before the checkpoint, at ~30 mph max once on. Take them off on bare pavement.
- ▸Ski-area lots are where people get stuck: plowed berms, packed ice, a foot of new snow. Traction boards and a shovel get you out without waiting for the lot attendant.
- ▸A closure can hold you on the pass for hours. Fuel above half, blanket, water, snacks, and a way to keep the phone charged.

The fastest way out of a plowed-in parking spot or a berm. Dig the tire face, wedge, ease on.

Hours stopped on a pass with the engine off is a real scenario. A heavy wool blanket is the piece that makes it boring instead of dangerous.

- ▸Practice the chain install in your driveway. The first attempt on a dark shoulder at 25°F in a snowstorm is how people give up and turn around.
- ▸If the exhaust pipe is in a snowbank, don't idle for heat — clear it first. Carbon monoxide in the cabin is silent.
- ▸AWD isn't a chain exemption at the highest control level, and it isn't a substitute for winter tires at any level.
Frequently asked questions
Are snow socks legal instead of chains?
In many places, yes — AutoSock is approved by Caltrans as an alternative traction device and accepted in a number of other states. But rules differ by state and sometimes by pass, and some jurisdictions still require steel chains at the highest level. Check your state's DOT before relying on them.
How fast can I drive with chains on?
About 30 mph maximum, and slower on cables and snow socks. Faster wears them out, throws them, and can damage the car. Remove them as soon as you're back on bare pavement.
