Winter Trucking Survival Guide: Ice, Snow, and Cold Weather
Winter Driving Techniques
The most dangerous winter hazard is black ice — a thin, nearly invisible layer of ice that forms on road surfaces, especially on bridges, overpasses, and shaded areas. The only reliable defense is reducing speed. If your truck starts to skid, do NOT hit the brakes. Instead, ease off the throttle, steer gently in the direction you want to go, and wait for traction to return.
Jackknifing prevention: avoid sudden braking on slippery surfaces. If you feel the trailer starting to push the tractor, gently accelerate to straighten the combination. Maintain longer following distances (at least 8-10 seconds in winter conditions versus 4-5 in dry conditions). Use engine braking judiciously — on ice, even engine braking can cause a skid if the drive wheels lose traction.
Chain Laws by State
Chain requirements vary significantly by state:
California: R-1 (chains required), R-2 (chains or snow tires on drive axles + traction devices on trailer), R-3 (chains on all axles). Fines up to $1,000.
Colorado: Traction Law (adequate tires required on I-70), Chain Law (commercial vehicles must chain up). Fines start at $651.
Oregon: Carry chains November through April on designated routes. Commercial vehicles need chains on drive axles minimum.
Washington: Must carry chains October through April on mountain passes. Traction tires may suffice in some conditions.
Always carry chains even in states where they are not legally required — you never know when weather will change, and being stuck without chains can strand you for days.
Winter Emergency Kit
Every truck should carry: extra warm clothing (insulated coveralls, winter boots, gloves, hat), emergency blanket or sleeping bag (in case your truck loses heat), flashlight with extra batteries, tire chains and a chain tool (bungee cords make installation faster), windshield washer fluid rated for -20°F, cat litter or sand (for traction under tires), ice scraper and snow brush, jumper cables or a jump starter pack, and 3 days of non-perishable food and water.
Also keep your fuel tank above half at all times in winter. Diesel fuel can gel in extreme cold — use a fuel additive when temperatures drop below 10°F. Many truck stops sell anti-gel additives at the fuel desk.
Frequently Asked Questions
When should I chain up?
Chain up when road conditions require it (packed snow, ice) or when chain controls are in effect. Always chain up BEFORE the conditions get bad — installing chains on an icy grade is extremely dangerous. Pull into a chain-up area at the first sign of deteriorating conditions.
How long does it take to put chains on a semi?
An experienced driver can install chains on a single drive axle in 15-20 minutes. Your first time will take 30-45 minutes. Practice installing chains in good weather so you are prepared when conditions demand it.
Can my carrier force me to drive in dangerous winter conditions?
No. FMCSA regulations give drivers the right to refuse to operate in conditions they consider unsafe. Document the conditions (photos, weather reports) and notify your carrier in writing. Your decision to park is protected under 49 CFR 392.14.
