Most cars have some sort of emergency stash rattling around in the trunk: a dead flashlight, a tangle of jumper cables, a water bottle from three summers ago. The goal isn’t to haul around a survival bunker. It’s to carry a small, well-chosen set of supplies that will keep you safe, visible and reasonably comfortable until you can get moving again or help arrives.
Key Takeaways
- Start with a core layer of safety and communication gear, then add tools and seasonal supplies as space allows.
- Tailor the kit to your climate, your passengers and how far you usually drive.
- Check it twice a year so your flashlight, water and the spare tire are ready when you need them.
- Your best safety tool is judgment: get well off the road before you try to fix anything.
Think in Layers
Store-bought kits are a fine starting point, but they rarely match your car, your climate or your family. A more useful approach is to build in three layers: what you must have, what helps you fix common problems, and what keeps you comfortable if you’re stuck for a while.
Layer 1: Stay safe and get help
These items earn their space in every vehicle, every day of the year.
- Phone charging cable and a car adapter, plus a charged power bank
- A written list of emergency contacts, in case your phone dies
- Reflective warning triangles or roadside flares
- A bright flashlight or headlamp with a spare set of batteries
- A compact first aid kit
- A small fire extinguisher rated for vehicle use
- Your owner’s manual, kept in the glove box
Layer 2: Handle the common breakdowns
A dead battery, low tires and minor fluid issues account for a large share of roadside stops. These tools can turn a long wait into a short delay.
- Jumper cables or a portable jump starter
- A tire pressure gauge and a 12-volt tire inflator
- A quart of the correct motor oil and a jug of coolant
- A multi-tool, duct tape, zip ties and a few rags
- Basic hand tools: screwdrivers, pliers and an adjustable wrench
- Spare fuses matched to your vehicle
- Work gloves and a pen and notepad
Layer 3: Ride out a long wait
If you drive rural routes, take long trips or live where winter storms hit hard, add comfort and endurance items.
- Bottled water and shelf-stable snacks such as granola bars or nuts
- A warm blanket, a spare jacket, hat and gloves
- A folding “call for help” sign for the rear window
- A paper road map for areas with spotty cell coverage
- An empty, approved fuel container, stored securely
Pro Tip
Pack everything in a soft-sided bag or a lidded bin, and strap or wedge it in place. Loose heavy items can become projectiles in a sudden stop.
Seasonal Swaps
Cold Months
- Ice scraper and snow brush
- Folding shovel
- Sand or non-clumping cat litter for traction
- Extra blankets and hand warmers
- Winter-rated washer fluid
Warm Months
- Extra drinking water
- Sunscreen and a wide-brimmed hat
- Bug spray
- A reflective sunshade
- Extra coolant for hot-weather driving
A good habit is to make the swap when you change your clocks in spring and fall. It’s an easy reminder that comes twice a year.
Packing for Your Passengers
A kit built for a solo commuter looks different from one for a family minivan. If children ride with you often, add extra snacks, diapers or wipes as needed, a change of clothes, and a few small games or books to make a long wait easier. Pet owners should pack a leash, a collapsible bowl and some food. Anyone who relies on daily medication may want to keep a short emergency supply in the car, stored according to its label, since heat and cold can affect some medicines.
Keep It Ready: A Twice-a-Year Check
- Check the spare. Spare tires lose air quietly. Inflate it to the pressure listed on the tire or in your manual.
- Test anything battery-powered. Flashlights, jump starters and power banks should all be charged or loaded with fresh batteries.
- Refresh food and water. Replace items past their dates and swap out water bottles that have baked through a summer.
- Restock first aid supplies. Replace anything used and check expiration dates on ointments and medications.
- Practice once. Make sure you know how to use the jack, the jump starter and the inflator before you’re on a dark shoulder trying to figure them out.
Using Your Kit Safely
The supplies only help if you can use them without putting yourself in more danger. When trouble starts, signal and move as far off the road as you can, ideally to an exit, parking lot or wide shoulder. Turn on your hazard lights. If you’re on a busy highway, it’s often safer to stay buckled in your vehicle and call for help than to stand beside traffic.
Safety First
Never attempt a tire change on the traffic side of a vehicle on a busy road. If you can’t get fully clear of moving lanes, call for roadside help or police instead. In snow, keep the exhaust pipe clear if you run the engine for heat, to avoid carbon monoxide buildup.
Place triangles or flares well behind your car so approaching drivers have time to react, and keep everyone away from the roadway while you wait.
The Coverage Side of a Breakdown
Many auto policies offer optional roadside assistance or towing coverage that can help pay for jump starts, lockouts, fuel delivery, flat tire changes and tows. What’s included, and any limits on distance or number of service calls, varies by insurer. If a breakdown leads to an accident, your liability, collision and other coverages would apply according to your policy’s terms.
It’s worth confirming whether you carry roadside coverage before a long trip. The team at Callicott Insurance Agency can tell you what’s on your policy and what options are available.
Frequently Asked Questions
Is a pre-made kit good enough?
It’s a solid starting point. Most benefit from a few additions, such as a better flashlight, water, seasonal gear and items specific to your passengers.
Where should I keep the kit?
The trunk or cargo area works for most items. Keep a flashlight, phone charger and first aid kit within reach of the driver.
Flares or reflective triangles?
Both work. Triangles are reusable and don’t involve fire, which makes them a good choice near spilled fuel. Flares are brighter and easier to see from far away.

A good kit in the trunk and the right coverage on your policy make a breakdown far less stressful. Talk with Callicott Insurance Agency about roadside and auto coverage options.
