About this kit
Keep occupants warm, visible, and hydrated during winter strandings, and provide traction/clearing tools to self-recover from minor snow trouble.
A whiteout closes the interstate and traffic stops for four hours, or you slide into a snowbank on a rural road at night. The car may be your shelter until morning.
Required items 5
- Emergency blanket (mylar)×1 per seat
Plus at least one real wool or fleece blanket — mylar alone is miserable for hours.
- Hand warmers (air-activated)×6+ pairs
Rotate stock each season; they expire.
- Flashlight (handheld LED)×1
Winter strandings are usually dark strandings.
- Jumper cables×1 set
Cold kills marginal batteries — winter is jump-start season.
- Nitrile gloves×2 pairs
Under insulated gloves for wet, cold tasks.
Optional items 3
- Tire inflator (12V)×1
Cold snaps drop tire pressure ~1 PSI per 10°F.
- Duct tape×1 flat mini-roll
Taping a cracked window or torn weather seal buys hours of warmth.
- Headlamp×1
Digging out is a two-hands job.

Maintenance schedule
A kit you don’t maintain is a box of expired hope. Suggested cadence:
| Interval | Task |
|---|---|
| Each November | Install kit in vehicle; replace expired hand warmers; add fresh water and food bars. |
| Monthly (winter) | Verify the water hasn’t frozen and burst; test lights. |
| Each April | Remove seasonal items; note what was used or missing. |
Variations
Deep-cold (northern plains)
Add a sleeping bag rated to local lows, folding shovel, and traction boards.
Mountain travel
Add tire chains and know the chain-control rules for your routes.
⚠️ Safety notes
- If stranded in snow, clear the exhaust pipe before idling for heat — blocked exhaust causes carbon monoxide poisoning.
- Stay with the vehicle in a blizzard; it is shelter and far easier to find than a person on foot.
