Most winter car deaths happen not from the cold itself, but from people leaving a stuck vehicle to walk for help. This guide covers what to do if your car gets stuck in snow: how to try to get free, and if you can’t, how to survive safely while you wait.

Quick answer

Stay with your vehicle unless help is visibly close and you’re certain of the route — it’s a shelter, a locator, and a wind block that a person on foot doesn’t have. Run the engine 10 minutes an hour with a window cracked and the tailpipe clear of snow, keep a signal visible, and ration your fuel and any food and water. Try to free the vehicle only if you can do it quickly and safely.

First: try to get unstuck (briefly)

• Straighten the wheels and try gentle, steady acceleration — flooring it just spins the tires deeper into the snow or ice.
• Rock the vehicle by shifting between drive and reverse in short bursts if your transmission allows it, without spinning the wheels hard.
• Clear snow from around and under the tires, especially in front of (or behind) the direction you want to move.
• Add traction: sand, cat litter, or a traction mat under the drive wheels. Floor mats work in a pinch.
• Dig out the undercarriage if the car is “high-centered” on packed snow — a small folding shovel is worth its weight for this.
• Stop after a few honest attempts. Spinning the wheels longer just digs you in deeper and burns fuel and battery you’ll want later.

Why you should stay with the car

A vehicle is visible to searchers, blocks wind, and can provide intermittent heat — a person on foot in a storm has none of that and can lose the trail, visibility, and body heat fast. Search and rescue statistics consistently show people who left their stranded vehicle are far more likely to die of exposure than those who stayed. Only leave if you can see your destination, are certain of the distance and route, and staying is clearly more dangerous (fire, flooding, structural risk).

Make yourself visible

• Tie a bright cloth or the emergency triangle to the antenna or a side mirror.
• Raise the hood as a universal “need help” signal, when it won’t let more cold air in than you want.
• Turn on hazard lights briefly to save the battery, and a dome light at night when you hear or see anyone nearby.
• Keep the exterior visible — don’t let snow fully bury the car.

Running the engine safely

1. Check the tailpipe is clear of snow before starting the engine, and recheck it periodically — a blocked tailpipe pushes carbon monoxide back into the cabin.
2. Crack a window slightly whenever the engine is running, even a small gap, for ventilation.
3. Run it about 10 minutes each hour for heat, then shut it off to conserve fuel — a full tank can last many hours this way instead of a few.
4. Never sleep with the engine running unless you’ve just verified the tailpipe and are staying awake to monitor it.
5. If you smell exhaust or feel drowsy or headachy with the engine on, that can be carbon monoxide — turn it off and open windows immediately.

Staying warm without the engine

• Layer every piece of clothing you have; put on hats, gloves, and extra socks.
• An emergency blanket or sleeping bag in the car pays for itself the first time you need it.
• Move fingers, toes, and larger muscles periodically to keep circulation going without breaking a sweat.
• Huddle together if there are multiple people, and insulate against the seats and windows, which get very cold.

What to eat, drink, and how to signal

• Ration any food and water — snow can be melted for drinking water if needed but costs body heat to melt, so use the car heater or body heat to melt it in a container rather than eating it directly.
• A charged phone with a portable battery pack can call or text for help even with weak signal; texts often get through when calls don’t.
• A whistle carries farther than your voice and costs no energy.
• If you have a bright flashlight or headlamp, three flashes repeated is a recognized distress signal.

Build the kit before you need it

Everything above works far better with a stocked winter car kit already in the trunk: shovel, traction aid, blankets, extra clothing, food, water, a flashlight, a phone charger, and jumper cables. See our full winter car emergency kit checklist to build one before the first storm.

Before you drive in winter conditions

• Tell someone your route and expected arrival time.
• Keep the gas tank at least half full — it’s both range insurance and fuel for heat if you’re stranded.
• Check tires, wipers, and washer fluid rated for freezing temperatures before winter starts.
• Avoid travel during active storm warnings when possible; check road conditions before you go.

Frequently asked questions

Should you stay in your car if you’re stuck in the snow?

In almost all cases, yes. The car provides shelter, wind protection, and visibility for rescuers that a person on foot doesn’t have, and most winter exposure deaths happen to people who left a stranded vehicle. Only leave if your destination is visible, close, and certainly reachable, or if staying is clearly more dangerous.

How often should you run your car’s engine to stay warm?

About 10 minutes each hour, with the tailpipe checked clear of snow beforehand and a window cracked for ventilation. This provides periodic heat while conserving fuel far longer than running the engine continuously.

Can you get carbon monoxide poisoning in a stuck car?

Yes, if the tailpipe is blocked by snow, exhaust can back up into the cabin even with the engine idling normally. Always check and clear the tailpipe before running the engine, crack a window, and turn the engine off immediately if you smell exhaust or feel drowsy or headachy.

What should be in a winter car emergency kit?

A shovel, traction aid or sand, blankets or a sleeping bag, extra warm clothing, food, water, a flashlight, a phone charger or power bank, jumper cables, and a bright cloth or triangle to signal. See our full winter car kit checklist for the complete list.

Is it safe to eat snow for water if you’re stranded?

Eating snow directly costs your body heat and can worsen hypothermia. Melt it first using the car’s heater or body heat in a container, then drink it, rather than eating it straight.

How do you signal for help if your car is stuck in a snowstorm?

Tie bright cloth to the antenna or mirror, raise the hood, and keep the car visible above the snow line. A whistle, a flashlight signal of three flashes, and text messages (which often work with weaker signal than calls) are reliable ways to reach help.

Bottom line

Try briefly and carefully to get free, then stay with the vehicle, make it visible, run the engine sparingly with the tailpipe clear, layer up, and ration your supplies while you wait for help. A stocked winter car kit turns this from a genuine emergency into an uncomfortable wait.
