Over 1,300 people die annually in winter driving crashes. Don't become a statistic. This guide shows you exactly how to survive winter storms on the road.
Drawing on thousands of winter routing scenarios analyzed through advanced driving weather forecasts and input from experienced drivers, you'll learn proven strategies for preparation, critical decision-making, and emergency survival protocols.
What Constitutes a Dangerous Snowstorm for Travelers?
A snowstorm becomes dangerous for travelers when visibility drops below a quarter-mile, winds exceed 35 mph, or snow accumulates faster than road crews can clear it. These conditions create what emergency responders call the "deadly triangle" of reduced traction, poor visibility, and potential for becoming stranded.
Understanding Storm Classifications
The National Weather Service uses specific criteria to classify winter weather threats:
Winter Weather Advisory: Light to moderate snow expected (2-5 inches in 12 hours) with minimal travel impacts.
Winter Storm Watch: Conditions are favorable for significant snow, ice, or wind within 24-48 hours.
Winter Storm Warning: Heavy snow (6+ inches in 12 hours), ice accumulation, or blizzard conditions are imminent or occurring.
Blizzard Warning: Sustained winds of 35+ mph with considerable falling or blowing snow, reducing visibility to less than a quarter-mile for three hours or more.
Key Danger Indicators
Monitor these critical factors when assessing travel safety:
- Visibility: Less than half a mile becomes extremely hazardous
- Wind speed: Above 25 mph creates dangerous blowing snow
- Temperature: Below 20°F increases frostbite and hypothermia risks
- Snow rate: More than 1 inch per hour overwhelms road maintenance
- Road surface temperature: Below 32°F causes immediate ice formation
How Should You Prepare Before Traveling in Winter Weather?
Preparation starts 24-48 hours before your trip by monitoring forecasts, winterizing your car, and packing an emergency winter car kit. Without these critical steps, your chances of safe travel during winter storms drop dramatically, according to AAA winter driving safety data.
Vehicle Winterization Checklist
Your vehicle is your primary survival tool. Ensure these systems are winter-ready:
Tires and Traction
- Install snow tires or carry tire chains (required by law in mountain states like Colorado)
- Check tread depth using the penny test (Lincoln's head should be partially obscured)
- Maintain proper tire pressure (cold weather reduces pressure by 1-2 PSI per 10°F drop)
- Consider tire chains for severe conditions, even with snow tires
Fluids and Battery
- Use winter-grade oil (5W-30 instead of 10W-30)
- Fill windshield washer fluid with winter formula rated to -20°F
- Test battery capacity (cold reduces efficiency by 20-50%)
- Check antifreeze levels and freeze protection rating
Visibility Systems
- Replace worn wiper blades with winter-specific designs
- Clean all lights and reflectors
- Carry ice scraper and snow brush
- Test defrosters and heating systems
Essential Emergency Kit Components
Pack these items in an easily accessible container, following FEMA's emergency kit recommendations:
Warmth and Shelter
- Wool blankets or sleeping bags rated for expected temperatures
- Extra winter clothing (layers, hat, gloves, boots)
- Hand and foot warmers (chemical heat packs)
- Emergency bivvy or reflective blanket
Don't have time to assemble your own emergency kit? A pre-built emergency sleeping bag designed for extreme cold conditions can be a lifesaver. Look for bags rated to at least -10°F with compact storage and reflective materials for maximum heat retention.
Food and Water
- Non-perishable, high-energy foods (nuts, energy bars, crackers)
- Water (1 gallon per person) in insulated containers
- Thermos with hot beverages
- Can opener and eating utensils
Emergency food that won't spoil in your car: High-calorie emergency food bars are specifically designed for extreme temperatures and long-term storage. These compact bars provide the 2,000+ calories per day recommended for survival situations and won't freeze or spoil in your vehicle.
Communication and Tools
- Fully charged power bank and charging cables
- Battery-powered or hand-crank radio
- Bright flashlight with extra batteries
- Multi-tool with knife and pliers
- Duct tape and zip ties
Vehicle-Specific Items
- Jumper cables or portable jump starter
- Tow strap or chain
- Collapsible shovel
- Bag of sand or cat litter for traction
- Tire gauge and emergency tire repair kit
Upgrade from basic jumper cables: A portable jump starter with built-in air compressor eliminates the need for another vehicle and helps maintain proper tire pressure in cold weather. Look for units with USB charging ports to keep your phone powered during emergencies.
Essential digging tool for winter emergencies: A military-grade collapsible shovel takes up minimal space but can dig your vehicle out of snow, clear exhaust pipes, and even break ice. Choose models with serrated edges and multiple folding positions for maximum versatility.

What Are the Critical Decision Points During a Winter Storm?
The most critical decision is whether to continue driving or stop immediately when visibility drops below a quarter-mile or you feel unsafe. According to the American Red Cross, 80% of winter storm fatalities occur when drivers push beyond safe conditions rather than stopping.
Professional Driver Insight
EXPERT INSIGHT
"I've been driving trucks for 15 years, and I've learned that Mother Nature always wins. The loads that arrive late because you stopped for safety are better than the loads that never arrive because you didn't."
— Mike Peterson, Long-haul Driver, Minnesota
Emergency responder Captain Sarah Chen from Colorado State Patrol adds: "We see the same pattern every winter—experienced drivers who know when to stop, and overconfident drivers who think they can push through anything. Guess which ones we're pulling out of ditches?"
PRO TIP: Stay With Your Vehicle
80% of winter storm fatalities occur when drivers leave their cars to seek help. Your vehicle provides shelter, makes you visible to rescuers, and contains your emergency supplies. Unless help is immediately visible and you can safely reach it without losing sight of your vehicle, stay put and wait for rescue.
The "Go or No-Go" Decision Matrix
Use these criteria to make objective safety decisions:
Continue Driving When:
- Visibility remains above half a mile
- You can maintain safe following distance (8-10 seconds)
- Road surface shows recent plowing or treatment
- Traffic is moving steadily at reasonable speeds
- Your vehicle has adequate fuel (more than half tank)
Stop Immediately When:
- You cannot see beyond your headlight range
- Other vehicles are sliding or stuck
- You feel anxious or overwhelmed
- Fuel drops below one-quarter tank
- Any vehicle systems malfunction
Emergency Accommodation Options
- Use Kayak to quickly find nearby hotels with last-minute availability
- Check Expedia for bundled deals on emergency accommodations
- Look for TripAdvisor reviews of nearby hotels for safety and quality
Real-World Case Study: The 2016 I-75 Kentucky Pileup
On January 9, 2016, a sudden snowsquall on Interstate 75 in Kentucky caused a massive 27-vehicle pileup, killing three people and injuring others. The crash occurred when visibility dropped from clear conditions to near-zero in minutes.
What Went Wrong:
- Drivers continued at highway speeds despite deteriorating conditions
- No warning systems alerted drivers to the sudden weather change
- Following distances remained too close for conditions
Lessons Learned:
- Reduce speed immediately when snow begins, even if pavement appears clear
- Increase following distance to 8-10 seconds minimum
- Use hazard lights to alert following traffic when visibility drops suddenly
Navigation Strategies During Active Storms
When continuing travel is necessary, apply these proven techniques:
Speed and Following Distance
- Reduce speed by 50% from normal conditions
- Increase following distance to 8-10 seconds (count "one-thousand-one" to "one-thousand-eight")
- Avoid sudden acceleration, braking, or steering inputs
- Use engine braking instead of wheel brakes when possible
Visibility Management
- Keep headlights on low beam (high beams reflect off snow)
- Clean snow from lights, reflectors, and license plates every hour
- Use windshield wipers intermittently to prevent ice buildup
- Keep windows slightly cracked to prevent fogging
Route Selection
- Stay on major highways where possible (better maintenance)
- Avoid shortcuts through rural or mountainous areas
- Follow snowplow convoys at safe distances
- Watch for black ice on bridges and overpasses
How Do You Survive a Blizzard in Your Car?
If stranded, your immediate priorities are staying warm, conserving fuel, maintaining communication, and making your vehicle visible to rescuers. According to CDC guidelines on hypothermia prevention, most winter vehicle deaths result from carbon monoxide poisoning or hypothermia—both preventable with proper protocols.
Immediate Response (First 30 Minutes)
Stay With Your Vehicle: Your car provides shelter and makes you easier for rescuers to find. In blizzard conditions, disorientation can occur within seconds, and people have died just yards from their vehicles or from safety.
Assess Your Situation
- Check for injuries among all occupants
- Inventory fuel, food, water, and warm clothing
- Test cell phone signal and call for help if possible
- Note your exact location using GPS coordinates or mile markers
Establish Warmth Protocol
- Run engine for heat conservation (see critical guidelines below)
- ALWAYS clear snow from exhaust pipe completely before each engine start
- Open a window 2-3 inches (not just cracked) on the downwind side to prevent carbon monoxide poisoning
- Share body heat by sitting close together
⚠️ CRITICAL: Engine Running & Carbon Monoxide Safety
Carbon monoxide is the #1 killer in stranded vehicle situations. It is odorless, colorless, and deadly.
Before EVERY engine start:
- Check and clear exhaust pipe completely (snow can re-accumulate quickly)
- Open a downwind window at least 2-3 inches
- Watch for symptoms: headache, dizziness, nausea, confusion
Engine running schedule (adjust for temperature):
- Above 20°F: 10 minutes per hour
- 0°F to 20°F: 10-15 minutes per hour
- Below 0°F: 15-20 minutes per hour
- Extreme cold (-20°F or below): Up to 20 minutes per hour, monitor fuel carefully
If you have infants, elderly, or inadequate winter clothing, you may need to run the engine more frequently. Balance warmth needs against fuel conservation.
Long-Term Survival Strategy
Energy Conservation Running your engine continuously will quickly exhaust fuel. Instead:
- Follow the temperature-based engine running schedule outlined above
- Turn off during engine warm-up periods to conserve battery
- Use body heat and blankets between engine cycles
- Avoid sweating, which leads to dangerous cooling when you stop moving
Visibility and Signaling
- Tie bright cloth to antenna or door handle
- Raise hood to signal distress
- Use flashing hazard lights sparingly to preserve battery
- Create large "SOS" in snow visible from aircraft
- Use whistle or horn to signal rescuers (sound travels farther than voice)
Managing Resources
- Ration food and water (you can survive days without food, but only hours without warmth)
- Eat snow only if absolutely necessary (it lowers body temperature)
- Designate one person to stay awake and monitor conditions
- Keep activity level low to conserve energy

Winter Storm Driving Safety Tips: What to Do Before and During Travel
Follow these proven techniques to reduce your risk during winter travel, based on winter storm driving safety data from transportation authorities nationwide:
Before You Drive
- Clear all snow and ice from your vehicle, including the roof (flying snow endangers other drivers)
- Warm up your engine for 30-60 seconds for modern fuel-injected vehicles (older vehicles may need 2-3 minutes) - excessive idling wastes critical fuel
- Check weather conditions for your entire route, not just the forecast at your destination
- Fill your fuel tank - winter driving reduces fuel efficiency by 15-25%
- Inform others of your travel plans, route, and expected arrival time
While Driving
- Accelerate gradually to avoid wheel spin and maintain traction
- Brake gently and early - if your vehicle has ABS (anti-lock brakes), press firmly and steadily; do NOT pump. If you don't have ABS, pump brakes gently to prevent wheel lockup
- Turn slowly and smoothly to prevent skids and loss of control
- Maintain momentum on hills rather than stopping and trying to restart
- Stay home if conditions deteriorate beyond your comfort level
If You Start to Skid
- Don't panic or overcorrect - sudden movements make skids worse
- Take your foot off the gas and avoid hitting the brakes
- Steer in the direction you want the front of the car to go
- Straighten the wheel once you regain traction
- Practice recovery in a safe, empty parking lot before winter arrives
RV Considerations
⚠️ WARNING: Motorcycles and Winter Weather
Motorcycles should NEVER be operated in snow, ice, or winter storm conditions. This is not a matter of skill or preparation—it is fundamentally unsafe. Even light snow or temperatures near freezing create deadly conditions for two-wheeled vehicles. If winter weather threatens your route, transport your motorcycle in a vehicle or trailer, or postpone your trip entirely.
RV Travelers must consider:
- Higher center of gravity increases rollover risk
- Longer stopping distances require more space
- Propane systems need winter-grade fuel
- Water systems require antifreeze protection
- Plan RV-friendly accommodations using VRBO or TripAdvisor for RV parks and campgrounds
Frequently Asked Questions
How long can I survive in a stranded vehicle during a winter storm?
With proper preparation, most people can survive 2-3 days in a stranded vehicle. Critical factors include fuel for heat, adequate insulation, and avoiding carbon monoxide poisoning from blocked exhaust pipes.
Should I leave my vehicle to seek help during a blizzard?
Stay with your vehicle unless help is immediately visible and safely reachable without losing sight of your car. Your car provides shelter and makes you easier for rescuers to find—80% of winter storm deaths occur when people leave their vehicles. In blizzard conditions, even short distances can become disorienting and deadly.
What's the best way to call for help when stranded in snow?
Call 911 first if you have cell service, providing GPS coordinates or mile markers. If no service, try texting (often works when calls don't) or use your phone's emergency SOS feature.
How much food and water should I pack for winter emergencies?
Pack 2,000 calories worth of non-perishable food and one gallon of water per person per day. Energy bars, nuts, and crackers provide sustained energy without requiring heating.
Is it safe to run my engine for heat when stranded?
Yes, but follow critical safety protocols. Always clear snow from the exhaust pipe completely before each start and open a window 2-3 inches to prevent carbon monoxide poisoning. Run your engine based on temperature: 10 minutes per hour above 20°F, 10-15 minutes per hour from 0-20°F, and 15-20 minutes per hour in extreme cold below 0°F. Balance fuel conservation against warmth needs.
Conclusion
