Emergency Winter Car Kit: What You Need Before the Snow Hits
Snow, ice and extreme cold can turn an ordinary drive into a roadside emergency. A properly stocked emergency winter car kit can help keep you warm, visible and prepared until help arrives.
Build Your Winter KitWinter Emergencies Don't Always Give You Warning
A stalled vehicle, dead battery, sudden snowstorm or road closure can leave you sitting for hours in freezing temperatures. That's why an emergency winter car kit should be part of your cold-weather preparation before the first major storm arrives.
The goal isn't to pack your entire garage into the trunk. It's to carry practical supplies that can help you stay warm, communicate, make your vehicle visible and handle common winter roadside problems.
What Should Be in an Emergency Winter Car Kit?
Start with the essentials and adjust the kit for your climate, vehicle, passengers and the type of driving you normally do.
Warmth & Clothing
Pack a warm blanket or emergency blanket, extra gloves, a winter hat, warm socks and an extra layer of clothing. Cold becomes much more serious when you're sitting still for a long period.
Food & Water
Carry bottled water and shelf-stable snacks such as energy bars, nuts or dried fruit. Rotate food and water periodically so your emergency supplies stay usable.
Light & Visibility
A flashlight, spare batteries, reflective vest and warning triangles can make you easier to see during a nighttime or low-visibility roadside emergency.
Communication & Power
Keep your phone charged before winter trips and carry a charged portable power bank. A charging cable that stays with the kit is also a smart addition.

What to Do If You're Stranded in Snow or Extreme Cold
Having the equipment is only half the job. Knowing what to do when you're stranded is just as important.
Stay With the Vehicle When It's Safer to Do So
In many winter situations, your vehicle provides shelter and is easier for rescuers to locate than a person walking through snow. Unless remaining with the vehicle creates an immediate danger, avoid wandering away into severe weather.
Call for Help
If you have cellular service, contact emergency services or roadside assistance as appropriate. Give your location as accurately as possible and tell someone you trust where you are.
Make the Vehicle Visible
Turn on hazard lights when appropriate and use reflective warning equipment where it can be deployed safely. Visibility is especially important during blowing snow, darkness and poor road conditions.
Stay Warm Without Overexerting Yourself
Add clothing layers, cover your head and hands and use blankets. Gentle movement can help maintain warmth, but avoid exhausting yourself or becoming sweaty because damp clothing can make you colder.
Watch for Carbon Monoxide Danger
If you run the engine for heat, make sure the exhaust outlet stays clear of snow. Snow packed around the exhaust can allow dangerous carbon monoxide to accumulate inside the vehicle.
Don't Forget the Battery
Cold weather is hard on vehicle batteries. A battery that seemed fine during warmer weather can struggle when temperatures fall, which is why a portable jump starter can be one of the most useful pieces of winter roadside equipment.
Our Portable Battery Jump Starter Guide explains what these units do, what to look for and how to use one safely.

Prepare the Vehicle Before You Need the Kit
An emergency kit is your backup plan—not a substitute for winter vehicle preparation. Before severe weather arrives, check your battery, tires, lights, wipers and fluids, and keep enough fuel or charge available for unexpected delays.

Check Your Winter Kit Before Every Season
Don't build the kit once and forget about it. At the beginning of each winter, inspect batteries, food, water, medications or first-aid supplies, charging equipment and anything else that can expire, discharge or deteriorate.
It's also smart to check the kit before a long winter road trip. A few minutes of preparation in the driveway is much easier than discovering something is missing while you're stranded beside a snow-covered road.

Prepare Now. Drive With Confidence Later.
A good emergency winter car kit doesn't have to be complicated. Cover warmth, food and water, communication, visibility and basic roadside problems—and keep the kit ready before winter weather arrives.
