In short
- Cold exposes weak batteries — the number one winter failure.
- Check tyres, coolant strength, screenwash and lights before the weather turns.
- Carry a winter kit: scraper, de-icer, torch, warm layer, phone charger and basic breakdown essentials.
- Allow more time, tell someone your route on long journeys, and keep fuel or charge in reserve.
- If conditions beat you, stop somewhere safe early rather than pressing on.
1. What actually fails in winter
Batteries first, by a distance. Cold reduces a battery's output at exactly the moment a cold engine needs more effort to start, and short winter journeys with lights, heaters and demisters running never repay the charge. Tyres second — low tread and wrong pressures that were merely poor in July become dangerous on cold, wet leaves and ice. Then come frozen or diluted screenwash, coolant that is too weak to protect against frost, bulbs, wipers, and locks and doors frozen shut after a hard frost.
2. The autumn checks that prevent it
- Battery: have it tested before winter if it is more than a few years old or starting has begun to sound lazy.
- Tyres: pressures, tread depth and condition — remember wet and icy grip depends on them. Our puncture guide covers the checks.
- Coolant: the level and its frost protection strength, checked cold. See our overheating guide — coolant protects in winter too.
- Screenwash: topped up with proper winter-strength fluid, not plain water, which freezes.
- Lights and wipers: every bulb working, blades clearing without smearing. You will use both constantly.
- Fuel or charge: keep a sensible reserve. Winter journeys take longer, and queues with the heater on are not the place to run empty.
3. What to carry
Build the full kit in our breakdown kit guide; the winter additions are an ice scraper and de-icer, a warm coat or blanket, gloves, a shovel if you travel rurally, and food and water on longer trips. Keep the scraper in the car you will actually use at 6am — not in the garage.
4. Smarter winter journeys
- Check the forecast and road conditions before long journeys, and be willing to delay.
- Clear every window, mirror, light and the roof properly — driving peering through a cleared postcard of windscreen is dangerous and unlawful.
- Allow much more time, increase following distances, and make every input — steering, braking, accelerating — gentler.
- Use a main road that is likely to be gritted rather than a shorter frozen lane.
- Tell someone your route and expected arrival on significant journeys.

5. If you get stuck
Stop somewhere as safe as possible, hazards on, and stay with the vehicle unless you can reach certain safety nearby. Keep the exhaust pipe clear of snow if you run the engine periodically for warmth, and open a window slightly. If you are stranded and conditions are severe, the emergency services come first — 999 before recovery. Our breakdown guide covers roadside safety in full, and SK Recovery operates through winter, day and night.
Common questions
Why do batteries fail in cold weather?
Cold reduces battery output while a cold engine needs more power to start. A battery that coped in summer can be exposed by the first hard frost.
Should I start my car and let it warm up on the drive?
Clear the windows fully and drive gently once you can see properly. Extended idling wastes fuel and is discouraged in some places; a gentle drive warms the car faster.
Do I need winter tyres in the UK?
They are not a legal requirement. Good tread depth, correct pressures and adjusted driving matter most for most UK drivers, though winter tyres do perform better in sustained cold and snow.
What screenwash should I use in winter?
A proper screenwash mixed to winter strength. Plain water freezes in the bottle, pipes and jets exactly when you need them.
Do you recover vehicles in snow and ice?
Yes, subject to reaching you safely. Tell us about conditions and access when you call so the job can be planned.
