Winter Car Emergency Kit: What to Keep in Your Trunk

A winter breakdown can be dangerous if you are stuck in the cold with no supplies. A small emergency kit in the trunk costs little and can make a big difference. Here is what to pack.

This guide is based on published specifications, manufacturer information and buyer feedback. We do not claim hands-on testing. Always follow your vehicle manual and local laws.

Core items

Item	Why you want it
Portable jump starter or jumper cables	Cold weather kills weak batteries. See our jump starter guide
Portable tire inflator and gauge	Pressure drops in the cold. See tire inflators
Flashlight or headlamp and spare batteries	Hands-free light for roadside tasks
Warm blankets, gloves, hat	Heat can be lost fast if the engine is off
Ice scraper and snow brush	Clear every window and light
Small shovel	Dig out wheels from snow
Traction aid (sand, kitty litter, or mats)	Helps tires grip on ice
First-aid kit	For minor injuries
Reflective triangles or flares	Make the car visible
Power bank and phone cable	Keeps your phone alive to call for help
Water and non-perishable snacks	In case of a long wait

Nice-to-have items

• Tow strap and work gloves.
• Multi-tool and duct tape.
• Windshield washer fluid rated for low temperatures.
• Hand warmers.
• Whistle for signalling.

Before the season

• Have the battery tested, since most winter breakdowns start there.
• Check tire tread and pressure, and consider winter tires if you live in a cold climate.
• Top up antifreeze and wiper fluid and replace worn wipers.
• Keep the fuel tank at least half full.

If you get stuck

• Stay with the vehicle; it is easier to find than a person on foot.
• Make sure the exhaust pipe is clear of snow before running the engine, to avoid carbon monoxide risk.
• Run the engine briefly for heat rather than continuously, and crack a window for ventilation.
• Call for help and share your location.

Frequently asked questions

Where should I keep the kit?

In the trunk or cargo area in a bag so items do not slide around. Keep a few essentials like a charger within reach.

Do I need a kit if I drive only in town?

A smaller one is still useful. Most winter problems happen close to home, such as a dead battery in a parking lot.

How often should I check it?

At the start of each winter. Replace expired food, batteries and first-aid supplies.
