Winter road trips can be magical--snow-covered mountains, quiet highways, cozy destinations. But they also demand respect and preparation. Here are 10 tips that could save your life.
TL;DR
- Check conditions along your entire route, not just at the destination
- Pack emergency supplies: blankets, water, food, flashlight, phone charger
- Leave extra following distance (8-10 seconds on ice)
- Know your vehicle limits--AWD helps acceleration, not stopping
- If conditions worsen, pull off safely and wait it out
1. Check Conditions Before You Leave
Don't just check the weather at your destination. Use a route-based weather tool like Route Outlook to see conditions along your entire path. Mountain passes and elevation changes can create dramatically different conditions than what you'd expect from a point forecast.
2. Leave Early and Allow Extra Time
Winter driving is slower driving. Plan for your trip to take 25-50% longer than usual. Leaving early gives you daylight hours and flexibility if conditions worsen.
3. Keep Your Gas Tank at Least Half Full
A fuller tank adds weight for traction, prevents fuel line freeze-up, and ensures you won't run out if you're stuck in traffic or need to run the heater while waiting out a storm.
4. Pack an Emergency Kit
Your winter emergency kit should include:
- Blankets and warm clothing
- Flashlight with extra batteries
- First aid kit
- Non-perishable snacks and water
- Ice scraper and snow brush
- Jumper cables
- Bag of sand or cat litter for traction
- Phone charger
5. Know How to Handle Skids
If you start to skid:
- Don't panic or slam the brakes
- Look where you want to go and steer gently in that direction
- Ease off the gas but don't brake suddenly
- For front-wheel skids: Let off the gas and steer straight until traction returns
- For rear-wheel skids: Steer in the direction you're sliding
6. Increase Following Distance
On dry pavement, the "3-second rule" works. On snow and ice, increase that to 8-10 seconds. You need much more distance to stop safely.
7. Know Your Vehicle's Systems
Understand how your car's safety systems work:
- ABS (Anti-lock Braking System): Apply steady pressure; the pedal will pulse
- Traction Control: Helps prevent wheel spin but can't overcome physics
- AWD/4WD: Helps you go, but doesn't help you stop or turn
8. Be Extra Cautious on Bridges and Overpasses
These freeze first because cold air circulates above and below them. Even when the rest of the road seems fine, bridges can be icy.
9. Watch for Black Ice
Black ice is nearly invisible--the road just looks wet. Be especially alert when:
- Temperatures are near or below freezing
- It's early morning or late evening
- You're in shaded areas
- You're near bodies of water
10. Know When to Stop
Sometimes the safest decision is not to drive at all. If conditions are severe, find a safe place to wait it out. No destination is worth your life.
Tire Pressure and Winter Performance
Cold temperatures cause tire pressure to drop — roughly 1 PSI for every 10°F decrease. If you inflated your tires to the recommended 35 PSI on a 70°F day, they could be down to 31 PSI on a 30°F morning. Underinflated tires reduce handling, increase stopping distances, and are more susceptible to damage from potholes.
Check your tire pressure at least monthly during winter, and always when cold (before driving). Your vehicle's recommended pressure is on the driver's door jamb sticker, not on the tire sidewall. If you drive in frequent snow, consider winter tires — they're made from softer rubber compounds that maintain flexibility below 45°F and have tread patterns designed to channel snow and slush. Modern winter tires on a front-wheel drive sedan outperform all-season tires on an AWD vehicle in braking and cornering tests on snow and ice.
How Cold Weather Affects Your Battery and Engine
Car batteries lose about 35% of their cranking power at 32°F and up to 60% at 0°F. If your battery is more than 3 years old, have it tested before winter. A battery that starts fine in summer may fail completely on the first truly cold morning. Keep jumper cables or a portable jump starter in your vehicle at all times during winter.
Engine oil thickens in cold weather, making the engine harder to start and reducing lubrication during the critical first few minutes of operation. Most modern vehicles use multi-viscosity oil (like 5W-30) that handles cold starts well, but check your owner's manual for cold-weather oil recommendations if you're in a region that regularly sees sub-zero temperatures. Let your engine warm up for 30-60 seconds before driving — not the 10 minutes your grandfather recommended, but enough to circulate oil to all moving parts.
Windshield and Visibility in Winter
Visibility is one of the most critical safety factors in winter driving. Start by replacing your wiper blades if they're more than 6 months old — cracked or worn blades leave streaks that become dangerous at night when oncoming headlights scatter through them. Consider winter-specific wiper blades with a rubber boot that prevents ice buildup on the blade mechanism.
Keep your windshield washer fluid topped off with a winter formula rated to at least -20°F. You'll use more washer fluid in winter than any other season, especially when driving behind trucks that spray salt and slush onto your windshield. Running out of washer fluid on a highway with no visibility is a genuine emergency.
Don't forget about the rest of your windows. Before you start driving, clear ALL windows, mirrors, your hood, and your roof of snow and ice. Snow blowing off your roof can blind the driver behind you (and is illegal in many states). A properly cleared vehicle takes 5 minutes of preparation that can prevent an accident.
What to Do If You Get Stranded
If you go off the road or get stuck in snow, your vehicle is your best shelter. Stay with your car — it's visible to rescuers and protects you from wind and precipitation. Run the engine for 15 minutes each hour for heat, but crack a downwind window slightly to prevent carbon monoxide buildup. Make sure the exhaust pipe isn't blocked by snow. Turn on your hazard lights and, if you have them, place reflective triangles or flares behind your vehicle.
Pro tip: Use Route Outlook to check conditions before you leave and find the optimal departure time to avoid the worst weather along your route.
