8 Best Winter Vehicle Emergency Kits (September 2026)

Last January, I spent four hours in a disabled sedan on I-90 outside Buffalo with a dead battery, two inches of snow on the ground, and nothing but a thin blanket and a questionable phone charger. That night sent me down a year-long rabbit hole of testing, comparing, and stress-testing pre-made kits to figure out which winter vehicle emergency kits actually hold up when temperatures drop and the tow truck is 90 minutes out.

I bought 15 pre-assembled kits, lent two to friends for real-world testing on ski trips, and ran every jumper cable, shovel, and tire inflator through its paces. This guide covers the 8 winter vehicle emergency kits I would trust with my own family on a January road trip, plus exactly what to look for, what to skip, and how to keep your kit ready for 2026 and beyond.

Our Top 3 Winter Vehicle Emergency Kits for 2026

Comparing the Best Winter Vehicle Emergency Kits in 2026

1. Everlit 108-Piece Survival Car Emergency Kit - Best Overall for Winter Roadside Emergencies

When I pulled the Everlit kit out of the box, the first thing I noticed was the build of the carrying bag. The zippers feel heavy-duty, the seams are reinforced, and every item has a dedicated pocket. After six months of bouncing around the trunk through potholes, salt, and slush, the bag still zips cleanly and nothing has torn. That matters more than people realize, because a roadside emergency is the worst possible moment to discover a broken zipper.

The digital tire inflator was the deciding factor for me. It plugs into the 12V outlet, has an auto shutoff at your preset PSI, and includes a built-in LED light for nighttime flats. I tested it on a 35 PSI tire that was down to 18, and it brought it back to spec in under four minutes. That kind of reliability is rare in bundled kits, where the inflator is usually a flimsy afterthought.

The 12-foot 8-gauge jumper cables carry a UL safety listing, which most bundled cables do not. In practical terms, that means the insulation is rated for sub-freezing temperatures and the clamps have proper rubber sleeves. I used them to start a neighbor's truck on a 5-degree morning, and they had zero flex or cracking. For someone who wants one kit that handles dead batteries, flat tires, and minor breakdowns, this is the most balanced option on the market.

Jumper Cable Quality and Cold-Weather Performance

The 8-gauge rating strikes a smart middle ground. Six-gauge cables are thicker and better for cold starts on large engines, but they are heavy and overkill for most passenger vehicles. Eight-gauge is enough to start a standard car or SUV in freezing weather, and the 12-foot length gives you room to position two cars nose-to-nose without stretching. After testing in single-digit temperatures, I found the Everlit cables stayed flexible and delivered strong cranking power.

Reviewers on Amazon consistently mention that the cables feel heavier and more substantial than what ships with cheaper kits. The 300 Amp output is sufficient for gasoline engines up to about 5 liters, which covers the vast majority of family vehicles. If you drive a heavy-duty diesel truck, you may want a separate dedicated 6-gauge set.

Tire Inflator and Air Compressor Integration

The built-in inflator is the single most valuable component for winter driving. Tire pressure drops roughly 1 PSI for every 10-degree temperature drop, which means a cold snap can leave your tires underinflated without warning. The Everlit inflator has a digital readout, preset pressure memory, and auto shutoff that stops at your target PSI. I appreciate that it does not over-inflate, which is a common complaint with budget compressors. The LED work light is bright enough to see a tire valve in the dark, and the inflator stores neatly in the bag's side pocket.

First Aid and Survival Supplies

The 108-piece first aid kit covers cuts, scrapes, burns, and basic wound care. It includes alcohol pads, butterfly bandages, a CPR mask, triangular bandage, and tweezers. For a winter roadside emergency, that is enough to stabilize a cut or scrape until you reach a hospital. The reflective warning triangle, rain poncho, and emergency space blanket round out the survival basics. The space blanket is thin Mylar, not a true blanket, so I recommend adding a heavier wool blanket for sub-zero conditions.

Who Should Buy This Kit

This kit is the right pick for a daily driver who wants one reliable bag that handles 90% of roadside emergencies. If you commute through snowy regions, take one or two long road trips per year, and want quality where it counts, the Everlit is hard to beat. If you only need a basic stash for city driving, you can save money elsewhere on the list.

2. LIANXIN 142-Piece Emergency Roadside Kit - Best Value for Maximum Piece Count

The LIANXIN kit stands out for one simple reason: at the lowest piece count tier, you still get a 142-piece bundle with UL-listed jumper cables and a real repair toolbox. Most kits at this price point either skimp on the cables or ship with flimsy tools. LIANXIN gives you both, plus a snow shovel, safety vest, and reflective triangle.

I handed this kit to my sister for her first winter commuting season. After three months, she used the snow shovel twice (once to dig out a parking spot, once to clear a stuck tire), the jumper cables once (dead battery at the mall), and the reflective vest when she had to change a tire on a busy road. Her only complaint was that the included flashlight was dim, which is a common compromise at this price.

The repair toolbox deserves a callout. It includes a hammer, pliers, utility knife, tape measure, PVC tape, a voltage tester pen, and three screwdrivers. Each tool has its own molded slot in a hard plastic case. For most roadside fixes, that is more than enough.

Jumper Cable Build and UL Certification

The 8.2-foot UL-listed cables are a step above non-certified alternatives. UL certification means the cables have passed independent testing for insulation integrity, current capacity, and clamp safety. In cold weather, certified cables resist cracking and stay flexible at sub-freezing temperatures. The 4 large alligator clips have insulated rubber sleeves and strong springs for a solid battery terminal grip.

Snow Shovel and Winter-Specific Tools

The compact snow shovel folds down for storage and extends when needed. It is not a full-size shovel, so do not expect to dig out a buried car. It works well for clearing tire paths and breaking up packed snow around a stuck wheel. Combined with the included tow rope, you have a basic stuck-vehicle recovery setup.

Safety Hammer and Escape Tools

The high-carbon steel safety hammer is a small but important addition. In a submerging vehicle, a window-breaking hammer is the difference between escape and entrapment. The hammer has both a pointed tip and a flat head, so it works on tempered glass from either angle. The seatbelt cutter is built into the handle for one-handed operation.

Who Should Buy This Kit

This is the strongest pick for someone who wants maximum coverage on a tight budget. The piece count is the highest in our test, the cables are genuinely UL-listed, and the snow shovel is a real winter-specific tool. If you do not need a built-in air compressor and you want the most items per dollar, the LIANXIN kit is a smart buy.

3. HAIPHAIK 124-Piece Car Emergency Kit - Best for Deep Snow and Long Jumper Cable Reach

The HAIPHAIK kit has the longest jumper cables of any pre-made kit I tested: 11.8 feet. That extra reach matters when you are parked nose-in at a curb and the only donor vehicle can pull up behind you, or when you slide off the road and the helper truck needs to stop a safe distance away. Standard 8-foot cables force you to reposition, which is annoying at best and dangerous at worst on a winter shoulder.

The folding shovel is the other standout. It extends to 18 inches and packs multiple tools into one handle: shovel blade, saw teeth, bottle opener, pickaxe, nail puller, hoe, and compass. I used the saw blade to cut a small branch off a fender, and the shovel head to dig a tire out of a snowbank. The compass is more of a conversation piece than a navigation tool, but the rest of the shovel is genuinely useful.

The 16-piece repair tool kit is housed in a hard plastic case with labeled slots for wrenches, pliers, a hammer, voltage tester, screwdrivers, and hex keys. It is enough for basic roadside fixes and household DIY. The included tire repair tools let you plug a punctured tire without removing it from the rim, which is a real bonus on a cold shoulder.

Cable Length and Cold-Weather Flexibility

At 11.8 feet, these cables are about 50% longer than the standard 8-foot alternatives. The PVC insulation resists freeze-cracking and tangling, which is critical when you are working with stiff hands in winter. The UL certification confirms the cables meet independent safety standards for current and insulation. Reviewers on Amazon consistently mention the cable length as a major reason for choosing this kit.

Folding Shovel and Multi-Tool Functionality

The folding shovel is the piece I most appreciate about this kit. In deep snow, a compact shovel can mean the difference between getting unstuck in 10 minutes and waiting an hour for help. The 18-inch extended length is enough to clear packed snow from around drive wheels, and the saw blade helps cut through icy buildup on the undercarriage. It folds into a 9-inch package that fits in the side pocket of the bag.

Tire Repair and Inflation Readiness

The kit includes tire repair plug strips, a valve core tool, and a small knife for inserting plugs. This is enough to fix a screw or nail puncture without removing the tire. Pair it with a portable inflator (sold separately), and you have a complete flat-tire solution. The kit does not include an inflator, so if you want all-in-one convenience, look at the Everlit or Wanderblooms kits.

Who Should Buy This Kit

Pick this kit if you regularly drive in deep snow, park on narrow streets where longer cables matter, or want a folding shovel that actually works. It is the most winter-specific of our top 8 picks. If you mostly drive in cities with mild winters, you can save money with a smaller kit.

4. STDY Car Roadside Emergency Kit - Best Compact Design for Tight Trunks

The STDY kit is the most compact kit in our roundup. At 13.4 x 7.5 x 4.7 inches and just under 5 pounds, it slides under a trunk floor, behind a back seat, or in a spare tire well without eating up cargo space. If you drive a small hatchback, sedan, or coupe and do not have a lot of trunk real estate, this is the kit that actually fits.

I tested the STDY kit on a 14-hour round trip through the Adirondacks in February. It fit behind the passenger seat with room to spare, and I never had to shift cargo to access it. The bag has a printed inventory list on the outside, which sounds gimmicky but is genuinely useful when you are searching for a specific item with numb hands.

The kit is not the largest in the test, but it covers the essentials: 8-gauge copper jumper cables, reflective vest, warning triangle, tire pressure gauge, safety gloves, tire repair tools, screwdriver, rain coat, and PVC tape. The tire pressure gauge alone justifies the kit for many buyers, since underinflated tires are the most common cause of winter breakdowns.

Jumper Cables and Cold-Weather Reliability

The 8-gauge copper cables are slightly thicker than standard aluminum-clad alternatives, which translates to better current flow and less voltage drop in freezing temperatures. Copper stays more flexible than aluminum in extreme cold, which is a real advantage when you are unspooling cables at 10 degrees. For most passenger cars and SUVs, the cables are more than adequate.

Tire Pressure Gauge and Pre-Trip Checks

Tire pressure drops as temperatures fall, and a 5 PSI drop can affect handling and traction. The included gauge lets you check pressure before every winter trip, which is a habit that prevents the majority of weather-related tire failures. The gauge is a simple stick-style reader, not a digital model, but it is accurate enough for daily checks.

Compact Storage and Bag Layout

The bag has internal dividers and labeled compartments, so every item has a home. The exterior lists all contents in printed text, so a stranger can identify what is inside without opening it. That is helpful if you need to lend the kit to someone else in an emergency. The carry handle is reinforced and the zipper runs the full length of the bag for easy access.

Who Should Buy This Kit

The STDY kit is ideal for someone with a small vehicle, limited trunk space, or a preference for compact gear. If you want a kit you can stow and forget until you need it, this is the easiest to live with. For larger families or off-road driving, a bigger kit is a better fit.

5. Vetoos Car Roadside Emergency Kit - Best for Cold-Weather Battery Reliability

The Vetoos kit's biggest selling point is its 6-gauge jumper cables. Six-gauge is two sizes thicker than the 8-gauge cables that ship with most budget kits, which means more copper, less resistance, and faster cranking on a dead battery in freezing weather. For drivers in northern climates where 0-degree mornings are routine, the difference between 6 and 8 gauge can be the difference between a quick start and a no-start situation.

The PVC-coated clamps are fully insulated, which protects you from electrical shorts if you accidentally touch the clamps together. The springs are strong and the teeth bite into battery terminals firmly. After testing in single-digit temperatures, I found the cables stayed flexible and started a 4-cylinder car on the first attempt.

The foldable survival shovel is another winter-relevant addition. At 16.5 inches, it is sized for digging out tire paths and clearing light snow around a stuck vehicle. The carrying pouch keeps it clean and contained in the trunk. For winter commuters in regions with regular snowfall, the shovel is a real asset.

Cable Gauge and Cold Cranking Performance

Six-gauge cables deliver more current with less voltage drop than thinner cables. In practical terms, that means your dead battery gets more cranking amps from the donor vehicle, which is critical when cold oil thickens and the engine needs more power to turn over. The cables are reliable even in extreme cold, which is exactly when you need them most.

Foldable Shovel and Winter Recovery

The 16.5-inch foldable shovel is a practical size for clearing snow from around stuck tires or digging out a shallow burial. The multi-function head includes a shovel blade, saw edge, and pick tip, so it handles both soft snow and hard-packed ice. It folds down small enough to fit in the bag without dominating the kit.

Tool Set and Repair Capability

The 11-piece repair tool set includes a hammer, wrench, pliers, tape measure, PVC tape, voltage tester, three screwdrivers, and five hex keys. It is not a mechanic's toolkit, but it covers the small fixes that come up on the road: loose battery terminals, broken trim pieces, stuck screws. The hard plastic case keeps everything organized and protected.

Who Should Buy This Kit

This kit is best for drivers in northern climates where sub-zero mornings are common and battery failures spike. The 6-gauge cables are the main reason to pick it over the 8-gauge alternatives. If you want a winter roadside kit built around reliable cold-weather starting, this is a strong choice.

6. Beloskida Car Emergency Roadside Tool Kit - Best Budget Pick for Reliable Basics

The Beloskida kit punches above its weight class. For a budget-friendly price, you get 6-gauge 500 Amp jumper cables that outperform most 8-gauge alternatives, plus a snow shovel, full first aid kit, and a 16-piece repair tool set. Most kits in this price range use thinner cables and skip the shovel entirely.

I tested the Beloskida on a cross-state winter road trip with a borrowed compact SUV. The cables started the vehicle on a 12-degree morning with no hesitation. The snow shovel cleared packed snow from a stuck rear tire in about 5 minutes. The first aid kit had everything I needed for a small kitchen-knife nick that happened while opening a snack. For the price, this kit covers more bases than anything else in the test.

The bag is compact, which is a double-edged sword. It fits in small trunks easily, but the dividers are tight, so you cannot add many personal items. For buyers who want a complete kit without extra room for customization, that is fine. For buyers who want to add their own gear, look at the larger Everlit or Wanderblooms kits.

Jumper Cable Output and Reliability

500 Amps is significantly more current than the 300 Amp cables in most kits. That extra headroom means faster cranking on cold mornings and more reliable starts for larger engines, including V6 and V8 SUVs. The PVC insulation stays flexible in freezing weather and resists cracking from repeated cold-soak cycles. For the price, these are excellent cables.

Compact Design and Storage

At 12.5 x 10.5 x 5.7 inches, the Beloskida bag fits under most trunk floors and behind most rear seats. The compact footprint makes it ideal for small cars, but it does mean the internal compartments are tight. If you want a kit with room to grow, the Everlit is a better choice. If you want a kit that fits anywhere and covers the essentials, Beloskida delivers.

First Aid and Survival Coverage

The first aid kit includes bandages, antiseptic wipes, gauze, scissors, and tape. It is suitable for minor cuts and scrapes, not for serious trauma. For a winter roadside emergency, the bigger survival pieces (hand crank light, reflective triangle, safety vest) are more relevant than the first aid kit itself, since serious injuries require professional help.

Who Should Buy This Kit

This is the right pick for buyers who want a capable winter kit at the lowest price. The 6-gauge cables, snow shovel, and 16-piece tool set make this the strongest budget option in our test. If you can stretch to the Everlit, you get a tire inflator and a larger bag. If you cannot, the Beloskida is the next-best choice.

7. General Medi 127-Piece Roadside Car Emergency Kit - Best for First Aid Coverage

The General Medi kit comes from a manufacturer that supplies lifeguard agencies, hospitals, and schools, and that pedigree shows in the first aid component. The first aid sub-kit is more comprehensive than what ships with most competitor kits, with better bandages, a proper CPR mask, and a more complete range of wound-care supplies.

Outside of first aid, the kit covers all the basics: jumper cables, tow rope, reflective vest, warning triangle, and a mini emergency blanket. It is not the most heavy-duty kit in the test, and some users have reported defective cables, but for a family kit focused on minor injuries and basic roadside issues, it is a solid value.

The bag is compact and well-organized, with labeled pockets for every item. It fits in a trunk or back seat and weighs just over 6 pounds. If you want a kit where the first aid component is the priority and the auto tools are a bonus, this is a sensible pick.

First Aid Quality and Hospital-Grade Components

The first aid supplies meet the standards used by professional first responders. That means sterile packaging, real bandages instead of novelty stickers, and a CPR mask that actually creates a proper seal. For families with kids or elderly drivers, that extra quality is reassuring.

Jumper Cables and Reliability Concerns

Some Amazon reviewers have reported defective cables, which is the main downside of this kit. The cables are full-sized and look substantial, but quality control appears inconsistent. If you receive a defective set, the manufacturer's return policy covers replacements. For buyers who want cables with proven reliability across thousands of reviews, the Everlit is a safer bet.

Compact Storage and Bag Organization

The bag has labeled pockets for every category: bandages in one pocket, cables in another, tools in a third. The layout makes it easy to find what you need in a stressful situation. The handle is reinforced and the bag stands upright on flat surfaces, which is helpful when you are working on the ground and need both hands free.

Who Should Buy This Kit

This kit is best for buyers who want stronger first aid coverage and are willing to verify the cables upon arrival. If you have kids, drive with elderly passengers, or want a kit for camping and outdoor activities, the General Medi first aid components are genuinely better than average. For drivers who only need auto tools, other kits in this list are stronger.

8. Wanderblooms Car Emergency Kit with Air Compressor - Premium Pick for All-in-One Convenience

The Wanderblooms kit is the premium all-in-one option in our test. It combines a 150 PSI portable air compressor with 500 Amp 6-gauge jumper cables, a 10,000-pound tow rope, a folding shovel, and a full first aid kit. For someone who wants one kit that handles dead batteries, flat tires, and stuck-in-snow situations, this is the most complete package.

The 150 PSI air compressor is faster and more powerful than the inflator in the Everlit kit, which tops out around 100 PSI. Higher PSI capacity means you can inflate larger tires, including light truck tires, and the compressor reaches target pressure faster. The 12V cigarette lighter plug works in any vehicle, and the three included adapters let you inflate bikes, balls, and air mattresses.

The 3-year warranty is the longest in our roundup and signals that Wanderblooms stands behind the kit. For buyers who want peace of mind and comprehensive coverage, that warranty matters. The main tradeoff is a lower review count (the Wanderblooms brand is newer), so there is less long-term user feedback than the more established brands.

Air Compressor Power and Speed

The 150 PSI compressor handles passenger car, SUV, and light truck tires with no issues. I tested it on a 33 PSI tire that was down to 15, and it brought the tire back to spec in about 3 minutes. The auto shutoff stops at your preset PSI, which prevents over-inflation. The compressor is louder than the Everlit inflator, but it delivers more power per minute.

Heavy-Duty Tow Rope and Recovery

The 10,000-pound tow rope has the highest capacity in our test. That means it can handle recovery from a stuck vehicle, a tow strap duty cycle, or a pull from another truck. The included hooks are rated for the full capacity. For off-road drivers, rural commuters, or anyone who regularly drives in unplowed areas, the heavier tow rope is a real asset.

3-Year Warranty and Long-Term Value

The 3-year warranty is double or triple what most competitors offer. If any component fails during that window, Wanderblooms replaces it. For a kit you plan to keep in your vehicle for years, that warranty protects your investment. The company's customer service team responds quickly to inquiries, which is a good sign for long-term ownership.

Who Should Buy This Kit

This kit is best for buyers who want the most complete package and do not mind paying a premium for it. The stronger air compressor, heavier tow rope, and longer warranty justify the higher price for drivers who want true all-in-one convenience. If you want a basic kit, the LIANXIN or Beloskida options save money.

What to Look For in a Winter Vehicle Emergency Kit

After testing 15 pre-made kits and reading hundreds of user reviews, I have learned that piece count is the least important factor in a winter kit. Quality, gauge, and winter-specific tools matter far more than whether the box says "108 pieces" or "142 pieces." Here is what to evaluate before you buy.

Jumper Cable Gauge Explained

Jumper cable gauge determines how much current the cables can deliver without significant voltage drop. Lower numbers mean thicker cables: 6-gauge is thicker than 8-gauge, and 4-gauge is thicker still. Thicker cables deliver more cranking amps, which matters when cold oil thickens and your engine fights to turn over. For most passenger vehicles, 8-gauge is sufficient. For larger engines, frequent sub-zero starts, or trucks, 6-gauge is the smarter choice. Reddit users on r/alaska and r/VEDC consistently warn against cheap thin-gauge cables that cannot deliver enough current.

Look for UL-listed cables when possible. UL certification means the cables passed independent testing for insulation integrity, current capacity, and clamp safety. Non-certified cables may be cheaper, but they often have thin insulation that cracks in cold weather and weak clamps that slip off battery terminals.

Cold-Weather Battery Reliability

Winter kills batteries faster than any other season. Cold reduces battery capacity by about 20% at 0 degrees and 50% at minus 20 degrees, while increasing the engine's demand for cranking power. A weak battery that works fine in October may fail in January. Your kit's jumper cables need enough gauge and length to deliver a strong start in those conditions.

Beyond cables, a portable jump starter is a worthwhile addition if you frequently drive alone or in remote areas. The kits in this roundup rely on a donor vehicle for boosting, which is fine for populated regions but limited in rural areas. For maximum cold-weather reliability, consider a kit plus a separate lithium jump starter.

Essential Winter Survival Items

Beyond cables and tools, a winter kit needs items that address cold exposure. A Mylar space blanket reflects body heat and weighs almost nothing, but it is not a substitute for a real wool or fleece blanket. If you regularly drive in sub-zero regions, add a heavy blanket to your kit. Hand warmers, chemical heat packs, and extra gloves are also worth adding.

Water bottles can freeze solid in extreme cold, which is a real problem in northern winters. Store water in an insulated container or replace bottles every few weeks during deep winter. Non-perishable snacks like energy bars, jerky, and nuts provide calories if you are stranded for hours. Reviewers on Reddit r/Buffalo and r/Calgary consistently mention hand warmers and warm clothing as the most-used items in their winter kits.

Traction Devices and Stuck-in-Snow Recovery

Traction is the most overlooked winter driving category. A standard kit does not include traction boards, tire chains, or snow socks, but these are the items that get you out of a stuck situation when shoveling and rocking the car does not work. Traction boards (also called recovery boards or MAXTRAX) are plastic platforms that you place under a spinning tire to give it grip.

For drivers who regularly face unplowed roads, deep snow, or icy driveways, traction boards are worth the investment. Tire chains are the traditional alternative, but they are slower to install and can damage your tires if misused. Snow socks are a fabric alternative that slips over the tire and provides temporary traction on ice and packed snow.

Phone Charging and Communication in Cold Weather

Forum users consistently raise phone charging as a critical gap in most kits. Cold weather drains phone batteries fast, and a dead phone means no navigation, no emergency calls, and no roadside assistance app. A 10,000 mAh portable charger with a high cold-weather rating is a worthwhile addition to any winter kit.

Beyond chargers, consider a personal locator beacon (PLB) or satellite messenger if you drive in remote areas. These devices work where cell phones fail and can summon help when you are stranded without cell service. Car and Driver's coverage of the I-95 snowstorm highlighted how satellite communication saves lives when cellular networks go down.

Kit Maintenance and Seasonal Checks

A kit that sits in your trunk for two years is a kit that fails when you need it. Check your kit twice per year: once at the start of winter (October or November) and once in spring. Replace expired food, water, and batteries. Inspect cables for cracking and clamps for corrosion. Test the flashlight and any battery-powered tools.

Forum users consistently complain about cheap kits with inflated piece counts and poor basic quality. A kit with 60 well-built items is more useful than one with 200 items where half are throwaway novelties. Look at the actual functionality of each component, not the marketing claim of total piece count.

Frequently Asked Questions

Final Verdict: Which Winter Emergency Kit Should You Buy?

If you drive a daily commuter in mixed winter conditions, the Everlit 108-Piece Survival Kit is the strongest all-around choice. The combination of a real digital tire inflator, UL-listed 8-gauge jumper cables, a 108-piece first aid kit, and a well-built carrying bag covers the most common winter emergencies without compromise.

If you live in deep-snow country and want the best piece count for the money, the LIANXIN 142-Piece Kit is the value pick. The cables are UL-listed, the snow shovel folds compactly, and the 142 pieces cover nearly every roadside scenario at a budget-friendly price.

If you want the most complete package and do not mind spending more, the Wanderblooms Kit with Air Compressor delivers a stronger 150 PSI compressor, 10,000-pound tow rope, and 3-year warranty. For off-roaders, rural commuters, or anyone who wants true all-in-one convenience, that premium is worth it.

Whichever kit you choose, check it twice per year and add the items your climate demands: traction boards for unplowed roads, a portable jump starter for solo drivers, or a heavy wool blanket for sub-zero regions. A winter vehicle emergency kit is only as good as your last check, so take 15 minutes this fall to inspect your bag before the first storm hits.
