Putting together a car emergency kit is one of the smartest things you can do as a driver, but the right contents depend on where you are going and what time of year it is. A kit that works for your summer commute may leave you stranded in a winter storm, and the gear you need for a cross-country road trip is different from what you keep in the car for daily errands. This guide gives you a printable-style checklist broken down by season and trip type, so you can build a kit that matches your actual driving needs. For a broader overview of emergency gear, see our Emergency Equipment Checklists.
Before You Start
Your emergency kit should be checked at least twice a year—ideally when you switch to daylight saving time in spring and fall. That is a natural reminder to rotate out expired items, replace used batteries, and adjust for the coming season. Keep everything in a durable, waterproof container that is easy to grab from the trunk or back seat. A small plastic bin or a dedicated bag works well. Make sure every family member who drives the car knows where the kit is and what is inside. For official guidance on car safety and emergency preparedness, visit Ready.gov.
Year-Round Core Kit
These items belong in every car, every day, no matter the season or trip length. They cover the most common roadside emergencies: a dead battery, a flat tire, a minor injury, or being stranded after dark.
| Item | Notes |
|---|---|
| Jumper cables | Choose cables long enough to reach between vehicles, even in awkward parking spots. |
| First aid kit | Include bandages, antiseptic wipes, gauze, medical tape, gloves, and a CPR mask. Add any personal medications. |
| Flashlight with extra batteries | A LED flashlight is reliable and bright. Keep batteries stored separately to prevent corrosion. |
| Reflective triangles or road flares | At least three triangles or flares to warn approaching traffic. Check your state laws on flare types. |
| Basic tool kit | Screwdrivers (flathead and Phillips), pliers, adjustable wrench, and a pocketknife or multitool. |
| Tire pressure gauge | A simple stick-style or digital gauge helps you check tires before long drives. |
| Spare tire, jack, and lug wrench | Verify that your spare is inflated and that you know how to use the jack and wrench. |
| Fire extinguisher | A small dry-chemical extinguisher rated for electrical and fuel fires. Mount it securely so it does not become a projectile. |
| Emergency whistle | Useful for signaling if you are unable to shout. |
| Phone charger and power bank | A car charger plus a fully charged portable power bank ensures you can call for help. |
| Paper map or road atlas | GPS can fail; a physical map of your region is a reliable backup. |
| List of emergency contacts | Write down phone numbers for roadside assistance, family members, and your insurance company. Keep it in the glove box. |
| Cash in small bills | Enough for a tank of gas or a meal in case card readers are down. |
Winter Additions
Cold weather brings specific risks: loss of traction, reduced visibility, and the danger of hypothermia if you are stuck for hours. Add these items to your core kit from late fall through early spring. The National Highway Traffic Safety Administration offers detailed winter driving tips that complement this checklist.
| Item | Notes |
|---|---|
| Ice scraper and snow brush | A long-handled brush with an integrated scraper clears windows and lights quickly. |
| Cat litter, sand, or traction mats | Spread under tires for grip on ice or snow. A small bag or foldable mat is easy to store. |
| Warm blanket or sleeping bag | A wool blanket or a synthetic sleeping bag rated for below-freezing temperatures. |
| Extra warm clothing | Include a hat, gloves, scarf, and an extra layer such as a fleece or insulated jacket. |
| Hand warmers | Disposable chemical warmers last several hours. Keep a few packs in the kit. |
| Windshield washer fluid | Choose a formula rated for low temperatures to prevent freezing. |
| Small shovel | A compact folding shovel helps dig out snow from around tires. |
| Emergency food bars | High-calorie, non-perishable bars that do not freeze solid. |
| Water in an insulated bottle | Keep water from freezing by storing it in a thermos or insulated container. |
Summer Additions
Hot weather creates its own set of problems: dehydration, heat exhaustion, and engine overheating. Swap or add these items when temperatures climb.
| Item | Notes |
|---|---|
| Extra water | Store at least one gallon per person. Rotate it out every few months to keep it fresh. |
| Sun protection | Sunscreen (broad-spectrum, SPF 30 or higher), a wide-brimmed hat, and UV-blocking sunglasses. |
| Coolant (antifreeze) | Check your owner’s manual for the correct type. A premixed 50/50 solution is easiest to use. |
| Windshield sun shade | Keeps the cabin cooler and protects the dashboard from cracking. |
| Insect repellent | Especially important if you stop in wooded or rural areas. |
| Rain poncho | Summer thunderstorms can appear without warning. A lightweight poncho takes up little space. |
| Hydration tablets or electrolyte powder | Helpful if you are exerting yourself in heat or waiting for help. |
Long Road Trips and Remote Areas
When you are driving hundreds of miles from home, especially through rural or desert regions, a breakdown can mean waiting hours for help. Add these items to your core kit plus the seasonal additions above.
| Item | Notes |
|---|---|
| Battery jump starter (portable) | A lithium-ion jump pack can start your car without another vehicle. Keep it charged. |
| Tire repair kit and air compressor | A plug kit and a 12-volt compressor let you fix a minor puncture and re-inflate the tire. |
| Tow rope or strap | A rated tow strap with loops (not hooks) for use with proper recovery points; if you are not experienced with recovery, call for professional help instead. |
| Traffic cones or warning triangles | More than the minimum three cones helps create a visible buffer zone on highways. |
| Extra non-perishable food | Trail mix, granola bars, canned goods with pop-tops, and a manual can opener. |
| Water purification tablets or filter | If you are stranded near a water source, these make it safe to drink. |
| Multitool with pliers and knife | A higher-quality multitool can handle unexpected repairs. |
| Signal mirror and whistle | For attracting attention from a distance. A mirror can be seen by aircraft. |
| Paper maps for the entire route | GPS dead zones are common in remote areas. Mark your route on a physical map. |
| Emergency shelter | A space blanket or a lightweight bivvy bag provides insulation if you have to stay overnight. |
| Pet supplies (if traveling with a pet) | Extra water, food, a leash, and a collapsible bowl. |
| Baby supplies (if traveling with an infant) | Diapers, wipes, formula, and a change of clothes. |
Commuter Kit
If your daily drive is short—under 30 minutes and within cell service—you can slim down the kit. Focus on items that get you back on the road quickly or keep you safe until help arrives.
| Item | Notes |
|---|---|
| Jumper cables or portable jump starter | Choose one; a jump starter is more convenient if you drive alone. |
| First aid kit (small) | A compact kit with bandages, antiseptic, and pain relievers. |
| Flashlight | A small LED light that fits in the glove box. |
| Reflective triangle (at least one) | One triangle is better than none, but three are recommended for full visibility. |
| Phone charger cable and power bank | Keep a dedicated cable in the car and a charged power bank. |
| Tire pressure gauge | Quick check when the tire pressure light comes on. |
| Basic tool kit (minimal) | A screwdriver, pliers, and a pocketknife cover most commuter needs. |
| Seasonal add-on | In winter add an ice scraper and a blanket; in summer add a bottle of water and sunscreen. |
What You Can Skip
It is easy to overpack an emergency kit. Some items sound useful but add weight and clutter without much benefit. Skip these unless you have a specific reason:
- Full change of clothes for every family member. One extra layer per person is enough; a full outfit takes up too much space.
- Cooking equipment. A camping stove and fuel are unnecessary for roadside emergencies. Non-perishable food that does not require cooking is simpler.
- Large tool chest. A basic tool kit handles most minor fixes. You are not rebuilding an engine on the shoulder.
- Multiple types of fire starters. One reliable lighter or waterproof matches in a sealed container is sufficient.
- Heavy-duty recovery boards. Unless you regularly drive off-road in mud or sand, cat litter or traction mats work for snow and light mud.

FAQ
How often should I check my car emergency kit?
Twice a year is a good rule of thumb—when you change your clocks in spring and fall. At that time, replace expired food, water, and batteries, and adjust seasonal items. Also check the condition of your spare tire and the charge on your jump starter or power bank.
Can I use a pre-made emergency kit from a store?
Pre-made kits are a convenient starting point, but they rarely contain everything you need for your specific climate and driving habits. You will almost certainly need to add items like extra water, a better first aid kit, or seasonal gear. Use a pre-made kit as a base and customize it using the checklists above.
Do I really need a fire extinguisher in my car?
A small fire extinguisher rated for electrical and fuel fires can stop a small engine fire before it grows. It is especially valuable for long trips or older vehicles. Mount it securely so it does not roll around. Check your local laws; some areas require one in commercial vehicles but not personal cars.
What should I do if I get stranded and have no cell service?
Stay with your vehicle—it provides shelter and makes you easier to find. Use your whistle or signal mirror to attract attention. If you have paper maps, identify your location and your planned route. Conserve phone battery by turning off non-essential apps. If you have a portable jump starter, you can use it to charge your phone even if the car battery is dead.
Building a car emergency kit that fits your season and trip type does not have to be complicated. Start with the year-round core items, then add or swap based on the weather and how far you are driving. Check it twice a year, keep it organized, and you will be ready for the unexpected.
