A winter car kit helps when a journey takes much longer than expected or you have to wait for help. The UK government’s Prepare campaign suggests a torch, phone charger or power bank, warm clothes and blankets, high-visibility clothing, jump leads, food and drink, a first aid kit and a shovel.
Pack for the people who actually travel in your car. A blanket hidden under luggage is less useful than one you can reach without unpacking on a dangerous roadside.
A practical winter car checklist
| Pack | Why it helps |
|---|---|
| Warm coat, hat, gloves and blankets | Waiting for help can be cold even if the journey began in a warm car |
| Water and shelf-stable snacks | Useful during a long delay; check dates and replace as needed |
| Torch or head torch with working batteries | Light without draining the phone |
| In-car charging lead and charged power bank | Contact breakdown help and share your location |
| High-visibility clothing | Helps others see you if it is safe to leave the vehicle |
| Ice scraper, snow brush and winter screenwash | Clear windows, lights and number plates before setting off |
| Folding shovel | May help clear snow where it is safe to work |
| First aid kit and essential medication | Household needs vary |
| Breakdown membership and emergency contacts | Keep details available if the phone has no signal |
| Jump leads or a suitable jump starter | Only if you know how to use them for your vehicle; follow its manual |
Store loose items so they cannot become projectiles during sudden braking. Keep the torch and high-visibility clothing where they can be reached from a seat. Check the power bank periodically, especially before a long journey.
If travelling with a baby, an older person, a disabled passenger or a pet, add what they would need during a delay. For long rural journeys, tell someone your route and expected arrival time.
Check the car before setting off
Look at the weather forecast and road conditions. The Highway Code’s adverse-weather rules advise checking the route and whether more snow or severe weather is expected. Consider delaying a non-essential journey when conditions are poor.
Clear snow and ice from the windows, mirrors, lights and roof. Check tyres, lights, wipers, screenwash and the state of the starting battery. Follow the vehicle maker’s instructions for winter equipment. A service or tyre professional can advise if you are unsure about tyre suitability.
Do not copy a continental winter-tyre or snow-chain rule from a general checklist. If travelling abroad, check official rules for each country on your actual route shortly before departure. Equipment requirements and seasonal dates can change.
If the car breaks down
First decide where you are. A motorway or high-speed road is different from a quiet local road.
On a motorway, follow the Highway Code’s breakdown rules. If possible, leave at the next exit or reach an emergency area. If you cannot, move left to a place of relative safety, use hazard lights and leave the vehicle on the side away from traffic if it is safe. Get behind a safety barrier and keep well away from the vehicle and moving traffic. If you cannot get to a safe place or exit safely, remain in the vehicle with seat belts on and call 999 for the police. Never put out a warning triangle on a motorway.
On another road, move the vehicle off the road if possible and use hazard lights if it obstructs traffic. The Highway Code says a warning triangle, if carried and if safe to place, goes at least 45 metres behind the vehicle on the same side of the road. Do not put yourself in traffic to use it. Your safety comes before recovering a shovel or fixing a puncture.
If snow has trapped the car, call breakdown help and share an accurate location. Follow the advice of emergency services or the road authority. Do not run an engine if the exhaust is blocked by snow: exhaust gases can contain carbon monoxide. Never shelter in a garage with the engine running. If you can safely clear a blocked exhaust without entering traffic, do so before considering engine use; if not, leave it off and seek help. Symptoms such as headache, dizziness or nausea require fresh air and urgent help; see NHS carbon monoxide advice.
A quick monthly check
Check that the torch works, the power bank is charged, the warm clothes still fit and food or medicines have not expired. Top up screenwash suitable for expected conditions. Before a longer trip, review weather and route alerts again.
The kit helps you stay comfortable and visible while waiting. The most important equipment remains a safe stopping decision, a charged phone and knowing the UK breakdown guidance for the road you are on.
