Why This Checklist Matters Before Every Winter Drive
Snow and ice are among the most dangerous road conditions American drivers face. According to the Federal Highway Administration, nearly 70 percent of the U.S. population lives in regions that receive significant snowfall, and weather-related crashes on snowy or icy roads account for thousands of fatalities and hundreds of thousands of injuries each year. The difference between a close call and a safe arrival often comes down to preparation made before the trip begins.
This checklist covers four core areas: your vehicle's mechanical readiness, your visibility and traction equipment, your emergency supplies, and your route awareness. Work through each group before you drive — not while you're already on the road. For a broader look at how weather affects driving decisions, see our complete safe driving overview.
Don't Skip Clearing Your Roof
Snow left on your vehicle's roof can slide onto your windshield when you brake, instantly eliminating visibility. It can also fly off at highway speed and strike the vehicle behind you. Many states have laws requiring drivers to remove snow and ice from their vehicles before driving — check your state's requirements before departure.
What You'll Need
Most of the tools and supplies below are inexpensive and should live in your vehicle throughout winter — not just on days when snow is forecast. Review our seasonal vehicle prep guide if you haven't already transitioned your car for cold-weather operation.
Ice scraper and snow brush
Clear all vehicle surfaces of snow and ice before and during your trip.
Jump-start pack or jumper cables
Restart a dead battery in cold conditions when another vehicle may not be nearby.
Portable phone charger (power bank)
Keep your phone operational for navigation and emergency calls if the vehicle battery fails.
Warm blanket and extra clothing layers
Maintain body warmth if you are stranded and engine heat is unavailable.
Traction aids (sand, kitty litter, or traction mats)
Provide grip under spinning tires to free a stuck vehicle on ice or packed snow.
Small folding shovel
Dig out snow packed around tires or underneath the vehicle when stuck.
State DOT 511 road conditions service
Access real-time road closures, plowing status, and incident reports along your route.
The Pre-Departure Checklist
Run through each category below before starting your engine. Items marked must are non-negotiable in any winter storm scenario. Should items are strongly recommended and reflect established best practices. Nice to have items add meaningful margin without being essential.
Vehicle Mechanical Readiness
Traction and Visibility Equipment
Emergency Supplies
Route and Conditions Awareness
When Not Driving Is the Safest Choice
No checklist eliminates the risk of driving in a severe winter storm. If your state or local emergency management agency has issued a travel ban or winter storm warning, the safest decision is to postpone your trip. Vehicles, cargo, and schedules can be replaced — always weigh the value of the trip against the genuine risk conditions present on the road.
On the Road: Adjusting Your Driving
Even a perfectly prepared vehicle handles differently on snow and ice than on dry pavement. Stopping distances can increase by two to ten times depending on road surface and tire type — a reality that surprises many drivers who aren't used to winter conditions. Brake gently and early, accelerate gradually, and steer smoothly. Abrupt inputs are the most common cause of winter skids.
Keep your following distance at a minimum of five to six seconds behind the vehicle ahead — double the dry-road standard. If visibility drops sharply, reduce speed well below the posted limit and use low-beam headlights, not high beams, which reflect back off falling snow. For context on how wet and slick roads create similar hazards, see where rain-related accidents actually happen.
If conditions worsen beyond what you prepared for, pull over to a safe location — ideally a parking lot or rest area — rather than the highway shoulder. Stay inside your vehicle, keep hazard lights on, and call for assistance. Abandoning a stranded vehicle on foot in a storm carries serious risk.
