A car kit should make a delay easier to manage for the people actually travelling. A long motorway commute, a school run and a trip through remote countryside need different amounts of equipment, but all benefit from a working phone charger, suitable clothing and a reliable way to call for help.
Start with the vehicle itself. Check tyres, lights, wipers and fluid levels according to the handbook, and address warning lights or faults before a journey. Supplies in the boot cannot compensate for an avoidable mechanical problem.
Pack for the wait
Choose warm layers, a waterproof outer layer, suitable footwear, a blanket, drinking water, appropriate food and a torch. Carry a charging lead that works in the car; a charged power bank gives you another way to charge after leaving it.
Add what particular passengers need. A child, a disabled adult or a pet may require supplies that are irrelevant to a solo commuter. Ask a pharmacist about transporting temperature-sensitive medicine rather than leaving it in permanent car storage.
Keep the kit secured and inspect it regularly. The inside of a car gets hot, cold and damp. Check packaging, battery condition and whether stored items remain appropriate for those conditions.
Put urgent items where you can reach them
High-visibility clothing, the torch and contact details should not require you to unload luggage beside traffic. Choose a safe cabin storage location that does not interfere with pedals, airbags or visibility.
Save breakdown cover details on paper as well as in your phone. Check whether the cover follows the person or the vehicle, which journeys it includes and how to get assistance. Tell another driver where the information is.
Learn the motorway response in advance
The Highway Code advises leaving at the next exit or service area if possible. Otherwise, move left to relative safety and put the hazard lights on. If it is safe and possible, get out on the side away from traffic and wait away from the vehicle and carriageway, behind a barrier where safe.
If you cannot reach relative safety or cannot safely get out, stay belted in with hazards on and call 999 for the police. Explain any disability or difficulty leaving the vehicle. Never put a warning triangle on a motorway or attempt roadside repairs there.
Read the full official guidance before a journey. Great Britain and Northern Ireland have separate Highway Codes; both are linked below. The guidance is more useful than a general instruction to “get out”, which does not account for a vehicle stopped in a live lane or a passenger who cannot safely exit.
Adjust the kit to the route
Add an ice scraper, de-icer and appropriate winter supplies when conditions require them. A shovel or extra footwear may be useful for a rural winter trip but does not make an unsafe journey sensible.
Check the forecast and official traffic information before leaving. Have another route or somewhere suitable to stop. For an electric vehicle, include a realistic charging plan and an alternative charger; for any vehicle, begin a remote or long journey with an appropriate range reserve.
Before the next long trip, test the torch and charging lead, replace unsuitable food or water and check that clothing fits the passengers. Keep the kit small enough to inspect easily and complete enough for the journeys you make.
