Why your car needs its own first aid kit

Most UK households have a first aid kit somewhere at home — usually a battered tin under the bathroom sink. The problem is that it stays there. When you are three hours into a long drive on the A1, or stuck in a service station car park with a child who has just been sick, the bathroom cupboard is no help at all.

A car kit is different. It needs to be compact, heat-tolerant, and organised enough that you can find a plaster one-handed while indicating. It also needs to cover the things that happen specifically on journeys: travel sickness, insect bites, sunburn, minor collisions, and the small emergencies that come with children, dogs, and long stretches between services. Build it once, check it twice a year, and you will rarely need it — but you will be very glad it is there when you do.

The glovebox layer: small, light, always within reach

Think of this as your everyday kit. It handles grazes, headaches, and sticky hands without you needing to pull over and unload the boot.

• Assorted plasters, including a few waterproof and blister-specific ones — new shoes plus a long walk at a service station is a classic combination.
• Antiseptic wipes and a small tube of antiseptic cream for grazes and minor cuts.
• Alcohol-free hand sanitiser and a pack of disposable gloves, folded flat.
• Paracetamol tablets for adults, kept in their original blister pack.
• Antihistamine tablets for hay fever, nettle stings, and mild allergic reactions.
• Travel sickness tablets — check the age suitability carefully, as many are not licensed for young children.
• Two or three sick bags, plus a roll of kitchen towel and a pack of wet wipes.
• A small pair of blunt-nosed scissors and a few micropore tape strips.

The boot kit: the bigger, deeper layer

The boot holds the items you hope never to open. Keep them in a rigid plastic box with a lid, or a soft pouch, so nothing rolls loose around the spare wheel. Store it where it will not become a projectile in a sudden stop — wedged beside a seat or in a secured crate is better than loose on the parcel shelf.

• Sterile gauze swabs and large sterile dressings for heavier bleeding.
• A crepe bandage and a triangular bandage, useful for support and slings.
• An instant ice pack for bumps, sprains, and insect bites.
• A foil emergency blanket, which also works well for shock and cold motorway breakdowns.
• A small torch with spare batteries — breakdowns rarely happen at midday.
• Saline pods or sterile eye wash for grit, sand, and splashes.
• A digital thermometer, plus burn gel and a roll of cling film for burns.
• A CPR face shield and at least four pairs of disposable gloves.
• Oral rehydration sachets, which are genuinely useful for sickness and heat.

Medicines for children and the family

Children's medicines deserve their own small labelled pouch, because doses depend on age and weight and you do not want to be reading tiny print at the roadside. Include children's paracetamol suspension and children's ibuprofen suspension if your child can take them, along with a measured dosing syringe rather than a spoon. Add an antihistamine suitable for your child's age, and a sachet or two of rehydration solution.

Write the doses on an index card and keep it in the pouch, along with each person's name, date of birth, allergies, and any regular medication. Keep everything in its original packaging with the patient information leaflet. If anyone in the car has a prescribed adrenaline auto-injector or asthma inhaler, treat it as part of the kit and check the expiry date with the rest.

Travelling with pets

Dogs and cats have different needs, and human medicines can be dangerous for them — never give a pet paracetamol or ibuprofen. A small pet pouch in the boot should hold self-adhesive bandage, a roll of cohesive vet wrap, sterile gauze, saline, tick tweezers, and a spare lead. A soft muzzle or a length of bandage can be useful if an injured dog is in pain and likely to snap.

Before a long trip, note the nearest vet practice to your route and destination, and carry your pet's vaccination record. A spare bowl and a bottle of fresh water are just as important as bandages on a hot day.

Storing, checking, and actually using it

A kit is only useful if it is in date and you know where things are. Make it a habit to go through the box when the clocks change in spring and autumn: replace anything used, bin anything past its expiry date, and check that liquids have not leaked or frozen. Heat destroys medicines quickly, so avoid leaving the box in direct sunlight or in a car that sits at 40°C all afternoon.

Finally, a kit is not a substitute for knowledge. A short first aid course — the kind run by recognised training providers across the UK — will teach you how to use a bandage, manage bleeding, and recognise the signs of anaphylaxis. In an emergency, call 999; for urgent advice that is not life-threatening, NHS 111 is the right starting point. Prepare well, drive safely, and enjoy the journey.
