A winter car emergency kit is useful even if you usually drive short distances. A breakdown, road closure, snow squall, or traffic delay can turn a routine trip into a long wait. Build a kit before severe weather arrives, check it at the start of the season, and adapt it to the climate and routes you actually drive.
Core supplies for the passenger compartment
- Warm layers, hats, gloves, and blankets for each regular passenger.
- Water and shelf-stable snacks, replaced before they expire.
- A flashlight or headlamp with spare batteries.
- A phone charging cable and charged power bank kept within safe temperature limits.
- A first-aid kit and any essential medication you may need during a delay.
- Reflective vest, warning triangles, or other visibility equipment used according to local guidance.
- Paper contact information and a list of roadside assistance details.
Vehicle and snow supplies
Depending on your location, consider a snow brush and ice scraper, a small shovel, traction material suitable for your vehicle and conditions, windshield washer fluid rated for freezing temperatures, and gloves for handling equipment. Check your owner’s manual before using traction devices or attempting recovery methods.
Keep the fuel tank adequately filled or maintain sufficient battery charge for the journey. Electric-vehicle drivers should plan charging stops with cold-weather range in mind and identify charging options along the route. Do not store loose heavy items where they can become projectiles during a sudden stop.
Before you leave
- Check the weather forecast and road conditions for the entire route.
- Tell someone your planned route and expected arrival time on longer trips.
- Inspect tires, lights, wipers, battery condition, and fluid levels.
- Charge your phone and download offline maps if coverage may be limited.
- Pack supplies where they are accessible without unloading the vehicle.
If you become stranded
Move out of traffic if you can do so safely, turn on hazard lights, and call roadside assistance or emergency services as appropriate. Make the vehicle visible. If you run the engine for heat, ensure the exhaust pipe is clear of snow and check that exhaust can disperse safely; carbon monoxide can be deadly. Never use a camp stove, charcoal grill, or fuel-burning heater inside a vehicle or enclosed space.
Stay with the vehicle when conditions outside are dangerous and it is safe to remain inside. Follow instructions from emergency responders and local authorities. In extreme cold, conserve phone battery and use supplies to keep passengers warm.
Review the kit monthly in winter
Replace used supplies, check batteries, inspect food and water, and confirm that roadside assistance information is current. The right kit depends on whether you drive in heavy snow, rural areas, mountain passes, or a milder climate.
