What belongs in a semi truck's winter breakdown kit?

Driver guide · National edition

Winter breakdown kit laid out on a semi truck bunk — blanket, flashlight, gloves, water and jumper cables, snow outside the window

What is the kit's job?

Keep you alive, visible, and able to wait safely for help in sub-freezing weather — in that order.

A winter breakdown is a survival problem first and a repair problem second

A truck that cannot run cannot heat the cab — your kit is the heat plan when the engine is off

What keeps you warm?

A rated sleeping bag or heavy blankets, a full change of dry clothes, insulated coveralls, winter boots, two pairs of gloves, and a stocking hat and balaclava.

Layers you can work in — you may have to chain, walk, or place triangles in the cold

Chemical hand and foot warmers — cheap, flat, and they work for hours

A way to heat the cab without the engine where your company allows it — and the fuel discipline not to idle the truck dry trying

What keeps you fed and functional?

Water that will not freeze solid in a bottle you can thaw, shelf-stable food for 48 hours, and a flashlight plus headlamp with spare batteries.

Cold kills batteries — including the ones in your flashlight; keep spares warm and rotated

A phone charging cable and a power bank, charged — your phone is the rescue tool, treat its battery like fuel

Medications for several days beyond the plan, not the exact plan

What does the truck need?

Triangles and a reflective vest (year-round law and sense), jumper capability where your company equips it, a tire gauge, basic hand tools, penetrating oil, spare fuel filter, and the winter front where your engine uses one.

Fuel anti-gel additive bought BEFORE the cold snap, added before fueling when temperatures fall (see the cold-start article in this series)

Sand or kitty litter for traction under the drives, and chains where your routes and the law require them — and the knowledge of how your set installs, practiced before the storm

Spare wiper blades and washer fluid rated for the cold — visibility failures strand trucks too

What is the rule for leaving the truck?

In extreme cold with no heat, staying with the truck is the default — it is the shelter, the landmark, and what rescuers are looking for.

If you must walk for help, leave a note with your direction, time, and callback number, and stay on the road, never cross-country

Tell dispatch and the service operator exactly where the truck is on the highway near the nearest exit before your phone is your only heat source of information
