The Road-Trip Emergency Kit: What to Actually Carry
The car emergency kit that turns a breakdown into a delay instead of a disaster — what the experts say to carry, what to do if you’re stranded, and how to scale it from city to backcountry.
A flat on a forest road, a dead battery in a trailhead lot, a closed pass and a long backtrack — road trips go sideways, and the difference between a story and a scare is usually a box in the trunk. The good news: a solid kit is cheap, compact, and you’ll build most of it once.
This guide covers what the experts (Ready.gov, AAA, NHTSA, the Red Cross) actually recommend carrying, what to do the moment you break down, and how to scale the kit from a city commute to remote backcountry. The printable PDF is a packing checklist.
What you’ll learn
- The core car emergency kit (what every car should carry)
- What to do the moment you break down — and the “Move Over” law
- Triangle/flare placement and the first-aid basics
- How to scale the kit: basic, winter, and remote/overland
- The one item that matters most where there’s no cell signal
The core kit
Ready.gov’s baseline car kit is short and smart: jumper cables, flares or a reflective warning triangle, an ice scraper, a phone charger, a blanket, a map, and sand or cat litter for traction. AAA expands it with the road-trip essentials: a portable jump starter, a tire inflator or sealant and the tools to change a tire, a first-aid kit, a flashlight with spare batteries, a multitool, a small fire extinguisher, work gloves, and a reflective vest.
For food and water, plan roughly a gallon of water per person and some nutrient-dense, non-perishable snacks. NHTSA’s short version is the same idea: phone + charger, first aid, flashlight, jumper cables, water, and food, so a breakdown doesn’t become an emergency.
The moment you break down
Get off the road if you safely can, turn on your hazard lights, and raise the hood to be visible. In most cases, if you’ve pulled away from traffic it’s safest to stay inside with your seatbelt fastened until help arrives — a vehicle is a poor place to stand next to on a live road.
If you set out reflective triangles, place the first ~10 feet behind the car, the second 30–60 feet back, and a third 100+ feet back at highway speeds. And know that every state has a “Move Over” law requiring other drivers to slow and move over for stopped vehicles — but plenty of drivers don’t, so keep yourself behind a barrier when possible.
First aid, kept simple
A good first-aid kit has antiseptic, an assortment of bandages, gauze, ointment, gloves, tweezers, and a few tools — plus any personal medications and a card with emergency contacts. Check it once a season and replace anything expired. You don’t need a field hospital; you need to handle a cut, a burn, or a blister well enough to get to real help.
Scale it to the trip
Think of it in three tiers (our framing, built from the expert lists). Basic: the core kit above — good for any paved trip. Winter: add a cold-rated blanket or sleeping bag, traction (boards or litter), an ice scraper, warm layers, and extra food/water. Remote / overland: add recovery boards, more water, and — the big one — a way to call for help with no cell signal.
That last item is the difference-maker off the grid: a satellite messenger or personal locator beacon (like a Garmin inReach or ZOLEO) can send an SOS to search-and-rescue from anywhere with a view of the sky, when your phone has zero bars.

The essentials
Start a dead battery solo; doubles as a power bank and light. The highest-value item in the kit.
Bandages, gauze, antiseptic, gloves — handle the small stuff on the spot.
Be seen on a shoulder day or night; reusable LED beats single-use flares.
Re-inflate a slow leak or top off cold tires roadside.
Common questions
What should be in a car emergency kit?
Jumper cables or a jump starter, first-aid kit, flashlight, reflective triangles/flares, a tire inflator + change tools, water and food, a blanket, a phone charger, gloves, and basic tools — plus winter or remote add-ons as needed.
What should you do if your car breaks down?
Pull off the road if you safely can, turn on hazards, raise the hood, and usually stay buckled inside until help arrives. Set reflective triangles behind you and remember other drivers must “Move Over,” but don’t count on it.
What do I need for emergencies where there’s no cell signal?
A satellite messenger or personal locator beacon (e.g., Garmin inReach, ZOLEO) — it can send an SOS to search-and-rescue from anywhere with a clear view of the sky.
How much water should I carry?
About one gallon per person as a baseline, more for remote or hot-weather trips, alongside non-perishable food.
