This guide is for drivers in snowy or cold places who want a kit in the trunk before the first storm, or who are building one as a gift.
A winter kit won’t prevent a breakdown, but it can turn a long wait in the cold into an uncomfortable one instead of a dangerous one. Put it together before the first snow.
The quick answer
NHTSA’s “stock your vehicle” list for winter:1
- A snow shovel, broom and ice scraper.
- Abrasive material such as sand or kitty litter, in case you get stuck.
- Jumper cables, a flashlight and warning devices (flares or emergency markers).
- A first aid kit, including a tourniquet, and any personal medicines you need.
- Blankets, bottled water and non-perishable food.
- A cell phone and a car charger.
Ready.gov’s car kit adds a map and lists a reflective triangle as an alternative to flares.2
Build the kit
| Category | Items | Our tip |
|---|---|---|
| Clearing snow and ice | Shovel, brush or broom, ice scraper1 | A compact folding shovel fits in most trunks. See our snow brush guide |
| Getting unstuck | Sand or cat litter1,2 | Store it in a lidded container so it stays dry |
| Power and light | Jumper cables, flashlight, phone charger1 | Check flashlight batteries every fall |
| Being seen | Flares, emergency markers or a reflective triangle1,2 | Keep them where you can reach them without unpacking the trunk |
| Staying warm and fed | Blankets, water, non-perishable food1 | Add a hat, gloves and dry socks for each regular passenger |
| Health | First aid kit, personal medicines1 | Replace medicines before they expire |
If you get stranded
NHTSA’s advice:1
- Stay with your vehicle and don’t overexert yourself.
- Clear snow from your exhaust pipe, and run the engine only from time to time, to avoid carbon monoxide building up inside.
Our advice: tie something bright to the antenna or window so you’re easier to spot, and keep your phone charged for calls, not scrolling.
Before winter starts
NHTSA also recommends a high-quality winter washer fluid with de-icer and checking your wipers and defroster.1
