Winter Storm Safety: Preparation, Survival, and What to Do
Last updated: 2026 | Winter storm survival guide | Posted by Ontario Towing
Winter storms present serious risks including blizzard conditions, stranded vehicles, and hypothermia. Being prepared before the storm, knowing how to drive during one, and understanding survival tactics if stranded can save your life. This guide covers complete winter storm safety from preparation through emergency survival.
Quick Answer: Prepare your vehicle before winter with a full inspection, emergency kit, and winter tires. During a storm, avoid driving if possible and reduce speed dramatically if you must travel. If stranded, stay in your vehicle, run the engine periodically for heat, keep the exhaust pipe clear of snow, and signal for help. Hypothermia is the primary danger.
Before Winter Storm Season: Vehicle Preparation
1
Check battery healthCold reduces battery power by 30 to 40 percent. Ensure the battery is charged and connections are clean.
2
Install winter tiresTread depth should be at least 4 to 6 mm. Winter tires provide significantly better grip in snow and ice.
3
Top off all fluidsEngine oil, coolant, windshield washer fluid rated for cold weather, and transmission fluid.
4
Test heating and defrosterEnsure heater, defroster, and all vents work properly before cold arrives.
5
Inspect brakes and lightsReliable braking and visibility are critical in winter. Have both checked professionally.
6
Keep fuel tank at least half fullYou may idle for hours if stranded. A half-full tank provides the running time you need.
Winter Storm Emergency Kit
Essential Supplies for Your Vehicle
Heavy blankets or sleeping bagRated for extreme cold. Hypothermia is the primary danger when stranded.
Extra winter clothingJacket, hat, mittens, socks, and boots. Stored in the trunk, not at home.
Jumper cables or portable jump starterCold drains batteries fast. Be prepared to restart your vehicle.
Flashlight with extra batteriesLED flashlights last longer. A headlamp frees both hands.
Food, water, and phone chargerGranola bars, nuts, bottled water, and a car charger plus portable battery pack.
Shovel, sand or kitty litter, ice scraperFor digging out and gaining traction. Essential for self-rescue.
Road flares or reflective trianglesMake your vehicle visible to rescuers and other drivers.
Safety During Winter Storms
Critical Rules for Storm Driving
Avoid driving if possibleStaying home is always the safest option during a winter storm.
Reduce speed to 40 to 55 km/hHeavy snow and ice require dramatically lower speeds. Icy conditions need even slower.
Increase following distance to 8 to 10 secondsStopping distance in winter is 4 to 10 times longer than dry roads.
Use low-beam headlightsHigh beams reflect off falling snow and reduce visibility.
No cruise controlMaintain manual speed control at all times on winter roads.
Avoid bridges and overpassesThese freeze before regular road surfaces and are especially dangerous.
If You Are Stranded in Your Vehicle
⚠️ Immediate Survival Actions
Stay in your vehicleYour car provides shelter and is visible to rescuers. Leaving dramatically increases danger.
Turn on hazard lightsPlace reflective triangles behind the vehicle if safe to do so.
Call for helpUse your phone to call 911 or roadside assistance. Provide your exact location.
Run engine for heat in 10-minute intervalsKeep the exhaust pipe clear of snow to prevent carbon monoxide buildup inside the car.
Keep moving inside the vehicleMove around to maintain circulation and prevent hypothermia.
Stay awakeHypothermia causes drowsiness. Keep yourself alert and engaged until help arrives.
Carbon monoxide warning: Running your engine with a snow-blocked exhaust pipe can kill. Check the exhaust pipe regularly when running the engine. Open a window slightly for fresh air every 10 to 15 minutes.
⚠️ Never walk for help in a winter storm. Staying in your vehicle is far safer. Your car provides shelter, is visible to rescuers, and has supplies. Walking in a storm increases the risk of hypothermia, getting lost, and exposure.
Yes, but safely. Run the engine for 10-minute intervals. Keep the exhaust pipe clear of snow to prevent carbon monoxide buildup. Do not run the engine continuously. Check exhaust regularly.
No. Stay in your vehicle. It provides shelter, is visible to rescuers, and has supplies. Walking in a winter storm dramatically increases the risk of hypothermia and getting lost.
A thin layer of frozen water on pavement that appears dark and nearly invisible. It looks wet but is actually ice with almost no traction. It forms on bridges, overpasses, shaded areas, and north-facing slopes.
Reduce to 40 to 55 km/h in heavy snow. Icy conditions require even slower speeds. The safest approach is to avoid driving entirely when roads are unsafe.
No. Never use cruise control on winter roads. You need manual control of acceleration to maintain traction. Cruise control can cause loss of control if wheels slip.
Shivering, confusion, drowsiness, slurred speech, slow heartbeat, and loss of coordination. Hypothermia develops quickly in extreme cold. Seek warmth immediately and call for help.
At least half a tank at all times during winter. Running out of fuel in cold weather is dangerous. A half-full tank provides enough running time for heat if stranded.
Winter tires with softer rubber compounds that maintain traction in cold temperatures and deeper tread patterns for snow. Install when temperatures consistently drop below 7°C.
