Winter car emergency kit: what to keep in your car

A winter car kit is about surviving a long, cold wait: blankets and warm clothes, water in plastic bottles, food that won’t spoil, a torch, a small shovel, a scraper and snowbrush, jumper cables and sand or cat litter for grip. Ready.gov also says to keep a full tank. If you get stuck, stay in the car, keep the exhaust pipe clear of snow and run the engine only in short bursts.

In short
The kit is for waiting safely, often for hours, until help or a snowplough arrives.
Water goes in plastic bottles so it can’t shatter when it freezes.
Warmth matters more than gadgets: blankets, a hat, gloves and dry socks.
A full tank means heat and a charged phone for longer.

Why winter needs its own car kit

Ready.gov warns that winter storms bring a higher risk of car accidents, hypothermia, frostbite and carbon monoxide poisoning, and that a storm can last from a few hours to several days. Snow closes roads and motorways in Europe and North America every winter, and drivers are sometimes stuck for many hours before help arrives. Your normal car kit (see our car kit checklist, including what the law requires in different countries) covers a breakdown. A winter kit covers the long, cold wait.

The checklist

This list combines the Government of Canada’s emergency car kit and Ready.gov’s winter advice, which mentions jumper cables, sand, a flashlight, warm clothes, blankets, bottled water and non-perishable snacks.

In the cabin

  • Warmth: a wool blanket or a sleeping bag per seat if you drive long distances, plus foil blankets, a hat, gloves, dry socks and spare shoes or boots. Canada lists extra clothing and shoes.
  • Water: in plastic bottles so they won’t break if frozen, changed every six months. Plan on at least 2 litres (0.5 US gal) per person for a long wait.
  • Food that won’t spoil: energy bars, nuts, dried fruit.
  • Light: a wind-up flashlight or a head torch with lithium batteries, which cope better with cold.
  • First aid: a car first aid kit; Canada adds a seatbelt cutter.
  • Signalling: a whistle to attract attention.
  • Phone power: a USB car charger and a charged power bank, since you may not want the engine running.
  • Paper: road maps, important numbers and a copy of your emergency plan.
  • Extra warmth: hand warmers take no space and work for hours.

In the boot (trunk)

Canada’s list also includes a candle in a deep can and matches. If you carry one, keep it upright in its can, away from fabric, and never leave it burning while you sleep.

Before every winter trip

  • Keep the tank full or close to it, as Ready.gov advises: fuel is your heat if you get stuck.
  • Check the weather and road conditions. Ready.gov’s advice in a winter storm is to stay off the roads if at all possible.
  • Charge your phone and tell someone your route and when you expect to arrive.
  • Have the battery, tyres, lights and wipers checked before the cold sets in.

If you get stuck in snow

  1. Stay in the car. Ready.gov: if trapped in your car, stay inside. It is shelter, and rescuers find cars more easily than people walking.
  2. Call for help and say exactly where you are. Switch on hazard lights or a beacon.
  3. Keep the exhaust clear. Clear snow from the exhaust pipe before running the engine, run it only in short bursts for heat, and open a window slightly. Carbon monoxide has no smell or colour; the NHS lists headache, dizziness, nausea and tiredness among the symptoms.
  4. Stay warm: blankets, hats and gloves on, huddle together, move your arms and legs.
  5. Watch for hypothermia: Ready.gov lists shivering, exhaustion, confusion, fumbling hands, memory loss, slurred speech and drowsiness. A body temperature below 35 °C (95 °F) is an emergency.
  6. Save power: phone on low-power mode, texts instead of calls.

Questions people ask

What should I keep in my car in winter?

Canada’s official car kit lists food that won’t spoil, water in plastic bottles, a blanket, extra clothes and shoes, a first aid kit with a seatbelt cutter, a small shovel, scraper and snowbrush, a wind-up flashlight, a whistle, road maps and a copy of your emergency plan. In the trunk: sand, salt or non-clumping cat litter, washer fluid, a tow rope, jumper cables, a fire extinguisher and warning lights or flares.

What should I do if I get stuck in snow in my car?

Ready.gov says that if you are trapped in your car, stay inside. Call for help, make the car visible, clear snow from the exhaust pipe before running the engine and run it only in short bursts for heat, with a window opened slightly, to avoid carbon monoxide build-up. Move your arms and legs to stay warm.

Will bottled water freeze in the car?

It can, which is why Canada’s list says plastic bottles, so they won’t break if frozen, and to change the water every six months. Keep a couple of bottles inside the cabin rather than the trunk so they freeze more slowly.

Do I need a jump starter or jumper cables?

Either works. Jumper cables are on the official lists and need a second car; a portable jump starter restarts a flat battery on its own, which helps on empty roads. Cold weather is hard on car batteries.

Is a warning triangle still required in Spain?

Since 1 January 2026, Spain requires a connected V-16 warning beacon to signal a breakdown instead of warning triangles. Rules differ by country, so check each country on your route.
