  • What’s In The Trunk: 10 Car Emergency Kit Essentials

What should you have in your car emergency kit?


Whether you’ve just bought your first car or are simply taking a moment to reassess the essentials you keep in your vehicle, there are a few things you should have in your car for emergencies.


With this list, you can make sure you’re prepared for many of the most common roadside issues, no matter whether you’re driving in wintry conditions or summer heat, an electric or gas vehicle, in the city or off the beaten path.

10 Things To Put On Your Car Emergency Kit List

It’s important to have an emergency kit for your home and for your vehicle, especially as natural disasters become more frequent and move to new areas. Here are some top recommendations for your emergency kit for your car. Take a peek and decide which are right for you, your vehicle, and the places you drive.

1. Flashlight & Flares

One of the most important things to have in your trunk is something you can use both to signal other drivers that you’re broken down or need roadside assistance and to light your way should anything happen after dark. 


While reflective gear is great (and also recommended!), something that reliably casts a light is a must for your vehicle. Be sure to check the batteries on your flashlight regularly and keep extras around just in case.

2. Reflective Triangle & Gear

Being able to see is important – and so is being seen. A flare or a flashlight is essential for illumination, but reflective clothes and a reflective triangle are equally essential. The clothing makes you more visible if you need to navigate around a broken down vehicle in an emergency at night and can protect you if, worst case scenario, you need to walk to safety along a poorly lit road without proper sidewalks.


While flares and reflective triangles serve similar purposes, you may want to consider having both. Flares are generally designed to be long-lasting and robust enough to stay lit even in rain and high winds and offer increased visibility, but a reflective triangle can give you extra reassurance that you’ll be seen no matter what should the flare, for example, get soaked to the point where it can’t be lit.

3. Provisions

One of the best things to keep in your car in case of emergency is water. This is especially true if you’re driving in the summer or somewhere hot, but really should be part of every emergency pack. 


Another essential to carry in your trunk kit is shelf stable snacks or ready-to-eat meals. You want something pretty calorie-dense and filling that will last in your trunk for quite some time. 


People who take emergency kit packing seriously – like those whose driving regularly takes them to more remote areas – will even buy what’s called MREs. These are military-style ration packs that stay good for several years and include everything you need to eat a full meal without any additional supplies. If you think you could end up somewhere far enough from emergency services that it might be necessary, MREs and water purification tablets can be a real lifesaver.

4. Jumper Cables

Whether you primarily drive out in the country or in the middle of a city, jumper cables are a great choice for an emergency kit. These cables can be used to jumpstart a weak or dead battery, helping you get your vehicle running again – at least long enough to get to a service station. Just make sure you know how to use them safely!

5. Tire Changing Kit, Repair Kit, & Spare

A dead battery is one common reason for breakdowns. Tire issues are another. It’s always wise to keep the tools necessary to change a tire and a fully inflated spare tire in your vehicle. In fact, your vehicle should have come with them – but if it didn’t, you’ll definitely want to pick them up. You’ll need a jack, a lug wrench, a spare tire, and your vehicle owner’s manual. 


If you want to go the extra mile, there are tire repair kits available that can help you fix minor tire issues, like sealing small holes. However, these repairs are only temporary – you’ll still need to replace the tire eventually.


If you’re handy, you may also want to keep a small array of useful items like duct tape, zip ties, or tools for minor vehicle repairs on hand – but only if you have the know-how to use them. 


With any additional tools you add to your kit, you’ll want to make sure they’re properly stowed such that they can’t come flying into the main cabin of the car in an accident. This is less of a problem in cars with traditional, separate trunks, but loose items can become dangerous in hatchbacks and SUVs that don’t have a solid divider.

6. Well-Secured Fire Extinguisher

Speaking of items that can be a huge help, but only if they’re properly stored! A fire extinguisher can’t solve every car fire, they’re not designed to fight massive fires, but can make a big difference should you end up in a situation that calls for one. 


Most experts recommend a standard 2.5-5 lb. ABC fire extinguisher, though some argue for Purple K extinguishers for car use. Do your own research and make a call about what makes sense for you. Just know that whichever you choose, it should be installed in a bracket that keeps the extinguisher from rolling around.

7. First Aid Kit

A first aid kit is one of the absolute essentials for any emergency kit. It’s something that can both help you and your passengers out in case of any minor injuries while in the car, but can also come in handy separate and apart from time spent in the car. Having the ability to triage wounds in a pinch can help you help others in need and handle emergencies of your own, no matter where the road takes you. 


As with provisions, if you’re someone who spends a lot of time far from emergency services – or someone who likes to hike or camp – you can step up to a more serious trauma kit like the Individual First Aid Kits (IFAKs) used by some emergency workers. While a standard first aid kit includes things for treating small cuts and burns, IFAKs might include things like a splint, packed gauze, additional burn treatment supplies, and an emergency blanket for hypothermia to triage more serious injuries.

8. Map, Compass, & Portable Phone Charger

When putting together an emergency kit for a vehicle, most of the focus is usually on handling breakdowns, accidents, and injuries, but sometimes you need a little help with the simpler things – like navigating in an area without cell service. It’s common today to rely on smartphones for directions, but there are still plenty of places where, depending on your carrier, the signal might be too weak to be sure you’re getting the information you need. If you’re worried you might be veering off track, a physical map can be a huge help.


On a similar note, we rely on our phones for so much – having a portable charger is never a bad idea. Maybe you usually charge by plugging into your car, but if that fails for any reason (or your car, say, needs to be towed), making sure your phone has a full battery is a must.

9. Overnight Bag

Another item that’s simply a good idea to have in your vehicle just in case is an overnight bag – a change of clothes, pajamas, essentials like a toothbrush, hairbrush, and deodorant, and a small amount of cash. This is another example of something that’s good in many different situations, not just in the case of car trouble. 


Maybe you’ve had a drink and don’t feel safe to drive. Maybe your house loses power or is put under an evacuation notice while you’re not at home. Or maybe your car does break down far enough from home that you need to get a hotel for the night. In any of these situations, you’ll be glad to have emergency supplies in your car to help you feel clean and comfortable, wherever you end up staying.

10. Inclement Weather Supplies

Last but certainly not least, this is possibly the widest category but perhaps the most important. Depending on where you are and the time of year, what you need to keep on hand can vary drastically, but it is always a good idea to have weather-appropriate emergency supplies in your car in case you have a breakdown and need to survive extreme weather for a time. 


Seasonal items to think about might include:


  • Sand or salt for roads

  • Ice scraper

  • Blanket

  • Hand-warmers

  • Spare winter clothes

  • Rainproof poncho or other rain clothes

  • Rain boots or winter boots

  • Sunscreen

  • Wide-brimmed hat

  • Sunglasses

  • Loose clothes

  • Electrolyte drinks

And Those Are 10 Useful Things To Have In An Emergency Kit For The Car

Of course, there may be other essential items that make sense for you and your family, and not all of these ideas make sense for every driver. If you’re in the backwoods of Maine in February, you’ll need different equipment than someone driving around the arid parts of Arizona in August. But with these items, you’ll be well on your way to being and staying prepared for whatever comes your way.
