Winter driving kit: 10 items you shouldn't travel without
A winter breakdown is not usually dangerous because of the car. It is dangerous because of the wait. The same 40-minute delay that is merely annoying in July can be genuinely serious at 20°F on an unlit road. These ten items fit in a single boot bag and change what that wait feels like.
1. A proper ice scraper and a stiff snow brush
Not the credit card in your wallet, and not the free plastic wedge that snaps on the first hard frost. A metal-edged scraper and a long-handled brush let you clear the whole car — all glass, mirrors, lights, and the roof. Clearing a letterbox-sized hole in the windscreen is how people drive into things they never saw.
2. A folding shovel
Almost every "stuck in snow" call is solved by clearing the snow packed under and in front of the drive wheels, plus a ramp of clear ground to roll onto. A compact folding shovel does this in five minutes. It also digs out a buried exhaust pipe, which matters more than most drivers realise — a blocked tailpipe pushes carbon monoxide back into the cabin while you sit there with the engine running for heat.
3. A wool blanket or a sleeping bag
The single most valuable thing in the bag. A car with a dead engine loses its heat in minutes, and you cannot count on running the engine indefinitely. Wool or a synthetic sleeping bag keeps working when damp; cotton does not. One per regular passenger, kept in the cabin rather than the boot so you never have to get out in traffic to reach it.
4. Jumper cables or, better, a lithium jump pack
Cold is what kills marginal batteries: a battery at 0°F delivers roughly half the cranking power it does at 80°F, exactly when the engine needs more. Cables need a second car and a willing stranger. A lithium jump pack the size of a paperback starts your own car in an empty car park, and doubles as a phone charger. Charge it at the start of each winter and check it monthly — a jump pack at 20% is a paperweight.
5. A torch with fresh batteries, plus a spare set
A headlamp is better still, because changing a wheel or looking under a bonnet in the dark takes two hands. Keep the spare batteries in a separate bag, not in the torch, and check them every autumn. Your phone's flash is a last resort, not a plan — the phone is also your only way of calling for help.
6. Traction aids: cat litter, sand or grit
Twenty pounds of non-clumping cat litter or coarse sand in a sealed tub is the cheapest recovery tool there is. Spread it in front of and behind the drive wheels for grip on packed ice. As a bonus, the weight over a rear axle helps traction on a rear-wheel-drive car. Traction mats or recovery boards do the same job better and cost more.
7. Water and dense, non-perishable food
A litre per person, plus nuts, dried fruit or energy bars — things that survive freezing and do not go stale. Keep water in the cabin, not the boot, where your body heat and the odd blast of the heater help stop it freezing solid. A frozen bottle is no use to anyone.
8. Warm layers you are not already wearing
Most winter breakdowns happen on the way to somewhere, dressed for somewhere — a smart coat, thin shoes, no hat. Keep a set of the boring stuff in the car: a wool hat, waterproof gloves, thick socks, and a pair of boots. Half of body heat loss is from the head and hands, and cold, wet hands make changing a wheel almost impossible.
9. A warning triangle and something high-visibility
Winter means early darkness, spray and low sun, and a stationary car is hard to see in all three. A reflective vest, kept where you can reach it from the driver's seat, means you can put it on before you get out. Reflective triangles or LED flares set out behind the car buy you the reaction time that matters most on a road where nobody can stop quickly.
10. A phone power bank and a cable that fits it
Cold flattens phone batteries fast, and a phone at 4% is the difference between waiting and being stranded. A charged power bank plus the right cable — checked, not assumed — keeps you reachable through a long wait. Keep the phone in an inside pocket rather than on the dashboard; warm batteries last considerably longer.
Two habits worth more than the kit
First, keep the tank above half through the winter. Fuel is heat, it is range to the next town, and a full tank does not have condensation freezing in the line. Second, tell someone your route and your expected arrival time before a long winter drive. Roadside help finds you far faster when there is someone who notices you are late.
Pack the bag once in November, check the jump pack and the torch batteries monthly, and you will spend the rest of the winter never thinking about it — which is exactly the point.
