A dead battery on a dark country road, a car slid into a snowbank, or a highway closed for hours by a storm. Winter breakdowns are stressful, but they become far safer when you have the right gear in the trunk. This guide shows you exactly what to put in a winter car emergency kit, what each item costs, where to pack it and what to do, step by step, if you ever get stuck.
Most checklists online just list items. We also cover the mistakes people make, what to add for kids and pets, and how to check your kit so it actually works when you need it.
Quick answer: A good winter car emergency kit includes a warm blanket, ice scraper, jump starter or jumper cables, flashlight with spare batteries, phone power bank, first aid kit, water, snacks, a small shovel, traction aid such as cat litter, warning triangle, gloves and a hat. Expect to spend around $80 to $150 for a complete kit.
Why You Need a Winter Car Emergency Kit
Cold weather makes every breakdown more serious. Batteries lose power in low temperatures, tires lose pressure, and help can take much longer to arrive when roads are icy or blocked. A winter car emergency kit keeps you warm, visible and connected while you wait, and often lets you fix the problem yourself and drive away.
The 25-Item Winter Car Emergency Kit Checklist
We have split the list into four groups so you can build your kit in stages if you are on a budget.
Stay warm
- Wool or thermal blanket (one per seat if you often carry passengers)
- Spare hat, gloves and thick socks

- Waterproof jacket or poncho
- Foil emergency blankets (light, cheap and easy to store)
Stay safe and visible
- Flashlight or headlamp with spare batteries
- Warning triangle or LED road flares
- High-visibility vest
- First aid kit
- Whistle to attract attention
- Brightly coloured cloth to tie to your antenna or door
Get moving again
- Ice scraper and snow brush
- Jumper cables or a portable jump starter
- Small folding shovel

- Tire pressure gauge
- Tow strap rated for your car’s weight
- Winter windshield washer fluid rated for freezing temperatures

Stay fed and connected

- High-energy snacks such as cereal bars, nuts and dried fruit
- Phone power bank and a charging cable
- Paper map of your area in case of no signal
- Emergency contact card with your breakdown cover number
Winter Car Emergency Kit Cost Breakdown

A pre-built winter car emergency kit can save time, but many are missing a shovel, traction aid or warm blanket. Check the contents and top up with the extras on our checklist.
How to Pack a Winter Car Emergency Kit So It Works
- Use a sturdy box or bag with handles so you can lift everything out quickly.
- Keep warm items in the cabin if you have room, such as under a seat. If your trunk is jammed shut in a crash or blocked by snow, you can still reach them.
- Store the scraper in a door pocket, not the trunk, so you never have to dig for it.
- Bag the snacks and water to stop leaks or crumbs spreading.
- Label the box so passengers can find things if you are hurt.
What to Do If You Get Stuck in Snow
Your winter car emergency kit only helps if you use it the right way. If your car is stuck or broken down in bad weather, follow these steps:
- Stay with your car unless you can see a safe building close by. A car is easier for rescuers to find than a person on foot.
- Call for help and share your exact location using your phone’s map app.
- Make yourself visible with the warning triangle, hazard lights and bright cloth.
- Clear snow from the exhaust pipe. A blocked exhaust can push carbon monoxide into the car.
- Run the engine for about 10 minutes each hour for heat, with a window opened slightly for fresh air.
- Wrap up in blankets and use hand warmers before you feel very cold.
- Move your arms and legs every so often to keep your blood flowing.
- Try to free the car only when it is safe: dig around the tires, spread cat litter in front of the drive wheels and accelerate gently.
Winter Car Emergency Kit Extras for Kids, Pets and Long Trips
- Children: Spare diapers or wipes, a change of clothes, a small toy and familiar snacks.
- Babies: Formula or ready-to-feed milk and a spare bottle.
- Pets: A collapsible bowl, water, a few days of food and a leash.
- Medication: A small supply of any daily prescriptions.
- Rural drivers: A second blanket, extra water and a fully charged spare power bank.
Winter Driving Tips That Reduce Breakdowns
A kit is your backup plan. These habits help you avoid needing it at all:
- Keep your fuel tank at least half full in winter.
- Get your battery tested before the first frost, especially if it is more than three years old.
- Check tire tread and pressure every month.
- Clear all windows fully before driving; our guide on how to defrost car windows shows the fastest methods.
- Tell someone your route and arrival time on long winter trips.
Check Your Winter Car Emergency Kit Twice a Year
Set a reminder in autumn and spring. Replace expired first aid items and snacks, swap old water, recharge your power bank and jump starter, and test your flashlight. A neglected winter car emergency kit with flat batteries and stale food will let you down when it matters.
