When you’re on the road, anything can happen. Minor cuts, scary scratches, and other mishaps might arise without warning, creating minor inconveniences at best and total chaos at worst. To stay prepared before you set off on a drive, read our helpful guide to creating the ultimate first aid kit for your car.
Of course, if you’d rather save yourself the work, you can opt to purchase a pre-made first aid kit instead.
Include wound care items
Before anything else, pick out an appropriate container for your first aid kit. Your container should be durable and easy to carry around, so they can withstand years of trips in the car.
No first-aid kit would be complete without the necessities required to treat wounds. These products help treat unexpected cuts, scrapes, and other injuries, preventing them from getting worse even when the nearest urgent care center is far away.
For proper wound care, drivers should take pains (no pun intended!) to include gauze and bandages to stop bleeding, antiseptic wipes and antibiotic ointment to prevent infection, and tweezers to remove splinters from skin.
A few other wound care items to consider:
Include pain relief measures
For general pain, be sure to include medications like aspirin, ibuprofen, or acetaminophen. Aspirin is even helpful for more serious medical events; because it prevents blood clotting, doctors sometimes advise patients to take aspirin in the midst of a heart attack. It’s important to keep in mind that when someone does take aspirin while experiencing a cardiac issue, they should alert their treating providers right away.
Self-cooling ice packs can also dull aches and pains, providing additional relief for minor injuries.
If you’ve got little ones in tow, you may want to pack liquid doses of pain medication. If you plan on stopping for any questionable roadside food, it might be a good call to incorporate anti-diarrheal medication.
Burn gel and aloe vera can be invaluable for taking the edge off of burns, and anti-itch creams like hydrocortisone are key for bad mosquito bites and nasty rashes.
Travelers should be aware that products like pain relief pills and creams may not be as effective if used past their expiration dates or stored in heat.
Include illness prevention measures
Injuries aren’t the only thing travelers must combat on the road. A simple cold can spread rapidly, dispersing discomfort through a group of road trippers at the speed of light. To avoid this frustrating problem, you should integrate illness prevention into your car’s first aid kit.
The first (and probably most obvious) step in this direction is hand sanitizer. When hand sanitizers are alcohol-based, as Dr. Poland of the Mayo Clinic explains, they “basically inactivate[s] the virus or the bacteria”. By rubbing sanitizer on your hands for at least 20 seconds, you can fight off sickness and avoid coughs, sniffles, and sneezes filling up your car.
Disinfectant wipes can help cleanse an area of germs, and many travelers pack them to periodically clean their car. Before pollen starts clogging the air, be proactive about seasonal allergies by stocking up on over-the-counter medications and nasal decongestant spray.
Include these miscellaneous items
Life comes at you fast, and stocking your first aid kit is the best way to prevent figurative (and sometimes literal!) headaches.
If you’ve got room in your car for more items, consider including a portable AED (automated external defibrillator), weather-appropriate gear, flashlights, and surgical masks.
In case you break down and get stuck in sizzling heat, you should also pack electrolyte packets to pour into water and replenish your energy. Come to think of it, a spare water bottle or two wouldn't hurt in case of emergency, either!
A thermometer for checking fevers, blankets for cold nights, and spare contact lenses are a few other things that could come in handy during car rides, but it’s up to each individual driver to determine what belongs in their first aid kit.
