Transportation · When transportation fails
Winter strands more drivers than any other season. Ice, snow, dead batteries, and road closures create the conditions. The preparation happens before the first freeze.
The season
Ice reduces tire grip by up to 80%. Snow obscures lane markings and road edges. Cold-start failures peak between December and February. Road closures multiply during winter storms. More drivers are stranded by winter weather than by any other single cause.
The preparation is straightforward and inexpensive. A pre-winter vehicle check, the right tires, a few seasonal additions to your emergency kit, and the knowledge of what to do if you get stuck. Every item on this page exists to solve a specific winter problem that people actually face.
Most winter vehicle emergencies are preventable. The battery that was weak in October dies on the first 10°F morning. The tires that were borderline in November have no grip on the first ice. The washer fluid that was low freezes in the lines. The fall transition catches all of these.
Before November
Do this once before the first freeze. Most items take 5 minutes; the battery test is free at any auto parts store.
Cold cranking amps (CCA) matter in winter. Get the battery tested free at AutoZone, O'Reilly, or any auto parts store. If it tests marginal, replace it now. A battery that struggles at 30°F will fail at 10°F.
Tread depth (the quarter test: insert a quarter head-down; if you see the top of Washington's head, you need tires), tire pressure (cold weather drops it 1 to 2 PSI per 10°F drop), and sidewall condition. Consider winter tires if you routinely drive below 45°F.
Check the coolant reservoir. The level should be between the min and max lines. If the coolant looks rusty or has been in the system for 5+ years, flush and replace. Antifreeze testers cost $5 and tell you the freeze-protection temperature.
Replace blades that streak. Fill washer fluid with a de-icing formula rated to -20°F or lower. Standard blue washer fluid freezes in the lines and sprayers.
Turn on the heat and the front and rear defrost. Confirm they actually blow hot air and clear the windshield. A non-functional defroster is a visibility hazard, not just a comfort problem.
Add winter items to the vehicle kit: ice scraper, snow brush, folding shovel, sand or cat litter, wool blanket, hand warmers, and tow strap. See the vehicle emergency kit for the full list.
The tire question
Winter tires outperform all-seasons below 45°F on every surface, including dry pavement. The rubber compound in winter tires stays flexible in cold temperatures, maintaining grip. All-season rubber hardens below 45°F, reducing traction even on dry roads.
On ice, winter tires can reduce braking distance by 25 to 50% compared to all-seasons. On packed snow, the difference is measurable in every test. The Mountain Snowflake symbol on the sidewall (not just M+S) indicates a tire that meets the industry snow traction standard.
The cost is $400 to $800 for a set of four, plus mounting and balancing ($60 to $100 per swap). Many drivers keep winter tires on a second set of steel wheels ($200 to $400 for the set), which makes seasonal swaps a 15-minute jack-and-lug job at home. Winter tires also extend the life of your all-seasons by splitting the wear across two sets.
Worth it if
Not worth it if you live in a mild climate where temperatures rarely drop below 45°F and snowfall is rare.
If it happens
You are off the road, the snow is heavy, and the plows are not coming soon. This is the protocol.
01
Almost always the right call. Your vehicle is shelter, it is visible to rescuers, and it has heat. Walking in a blizzard with reduced visibility is how people die within 100 yards of safety.
02
Turn on hazard lights. Place reflective triangles if you can safely do so. Tie a bright cloth to the antenna or door handle. At night, use interior dome light intermittently to save battery.
03
10 to 15 minutes per hour for heat. Crack a downwind window slightly to prevent carbon monoxide buildup. Clear the tailpipe of snow before each engine run. This is the most important safety step.
04
Snow-blocked exhaust pushes carbon monoxide into the cabin. Check the tailpipe every time before running the engine. Use the folding shovel to clear it. This step saves lives.
05
Call for help once, give your location, then minimize phone use. Low-power mode, screen brightness down, close apps. The power bank in your kit extends this significantly.
06
Wool blanket, hand warmers, extra layers from the kit. Move your arms and legs periodically to maintain circulation. Drink water. Eat snacks. Help is coming. Your job is to be alive and warm when it arrives.
The best decision
The most effective winter driving skill is knowing when not to drive. Social pressure, work expectations, and the assumption that everyone else is on the road create a powerful pull to go anyway. The prepared household resists that pull.
