Before leaving in a snowstorm, check the route first, then your tires, visibility, fuel or charge, and emergency supplies. If authorities advise against travel, roads are closed or visibility is deteriorating, a well-equipped car does not make the trip safe.
This guide covers the checks that matter immediately before departure, plus what to do if you skid, get a flat tire or become stranded. For maintenance ahead of the season, use our winter car checklist.

Should You Leave or Postpone?
A reliable car can still be the wrong vehicle for the conditions—and sometimes no vehicle is a sensible choice. Check the forecast for the entire journey, including the return trip, rather than only looking outside your house.
Review official road reports, closures, chain or traction requirements and local travel restrictions. Conditions can change sharply with elevation, exposure and distance from plowed main roads.
| What you find | Your decision |
|---|---|
| A closure, travel ban or official advice to avoid travel | Postpone and follow local instructions. Do not bypass barriers. |
| Freezing rain, whiteout conditions or rapidly worsening visibility | Delay departure rather than relying on the vehicle to compensate. |
| A route requiring equipment you do not have | Obtain compliant equipment before travel or choose a safe alternative. |
| Worn tires, poor defrosting or an unresolved starting problem | Address the problem before leaving. |
| An open route with manageable conditions and a prepared vehicle | Allow extra time, monitor changes and keep a plan to stop or turn back safely. |
How Many Inches of Snow Are Too Much?
There is no universal safe number. Two inches over ice can be more hazardous than deeper dry snow on a maintained road. Drifts can also be much deeper than the reported snowfall.
Ground clearance, tire traction, road treatment, visibility and terrain all matter. Snow reaching the underside of the vehicle can leave it stuck even if the tires still turn.
Is There a Temperature Below Which You Should Not Drive?
No single temperature applies to every vehicle or trip. Extreme cold affects starting, range and survival if something goes wrong. Ice can make travel dangerous near freezing, while a much colder, dry road may present a different situation.
Follow local warnings and your vehicle’s operating guidance. Consider how long help could take to reach you.
The Before-You-Leave Checklist
1. Clear the Entire Vehicle
Remove snow and ice from the windshield, side and rear windows, mirrors, lights and roof. Clear relevant cameras and sensors according to the manual.
A small scraped opening is not adequate visibility. Snow left on the roof can slide onto your windshield or blow onto another vehicle.
2. Confirm That You Can Keep the Glass Clear
Test the defroster, blower and wipers. Confirm that the washer system sprays properly and contains fluid rated for the expected temperature.
Release frozen wipers before operating them. Do not expect the blades to push heavy snow off the windshield.

- Do You Need Winter Wiper Blades?
- Car Heater Blowing Cold Air?
3. Check Tire Pressure and Condition
Use a gauge and the vehicle’s specified cold pressure. Look for damage, repeated air loss and uneven or inadequate tread.
Reaching the legal tread minimum is not evidence that a tire is suitable for snow. Do not treat a penny test as a complete winter-traction assessment.
4. Leave With a Fuel or Charge Reserve
A useful reserve gives you options if traffic stops, a charger is unavailable or the route changes. For gasoline vehicles, keeping at least half a tank during storm travel is a practical planning habit, not a guarantee against fuel-system problems.
EV drivers should account for cold-weather range changes, cabin heating, detours and charger availability. Follow manufacturer guidance for preconditioning and charging.
5. Do Not Ignore Existing Symptoms
Slow starting, warning lights, coolant leaks, unusual braking or severe vibration deserve attention before departure. A short pre-trip check cannot diagnose every fault.
Why Car Batteries Die in Cold Weather explains why a marginal battery can struggle when temperatures fall.
6. Pack for a Delay, Not Just the Drive
- Warm coats, hats, gloves, dry socks and suitable boots
- Substantial blankets or sleeping bags suitable for the conditions
- Snow brush, ice scraper and compact shovel
- Phone charger, charged power bank and flashlight
- Water, nonperishable food and necessary personal supplies
- Suitable tire equipment and roadside-assistance details
Keep essential supplies accessible. Tell someone your route and expected arrival time, especially for remote travel.

Do AWD, FWD or Winter Tires Make It Safe?
AWD Helps You Get Moving, but Grip Still Limits Stopping
AWD and four-wheel drive can improve the ability to accelerate on slippery surfaces. They do not create extra tire grip for every braking or cornering situation.
A vehicle that pulls away confidently can still slide at the next turn. Avoid using acceleration as a test of whether the road is safe.
Front-Wheel Drive Versus Rear-Wheel Drive
Front-wheel drive often provides useful starting traction because engine weight is commonly over the driven wheels. Rear-wheel-drive vehicles can also perform well with suitable tires, appropriate controls and careful driving.
The drivetrain label alone does not decide winter capability. Tires, weight distribution, ground clearance, stability control and conditions matter together.
Do You Need Four Winter Tires or Only Two?
When fitting dedicated winter tires, use a compatible set on all four wheels according to vehicle and tire guidance. Mixing a high-grip pair with substantially different tires can create an imbalance in handling.
Do not assume the non-driven wheels matter less: they still help the car steer, brake and remain stable.
Compare winter, all-weather and all-season tires before choosing a set.
Visibility, Black Ice and Skids
Drive for the Conditions
Reduce speed, leave substantially more space and make smooth steering, acceleration and braking inputs. A fixed following interval is not enough for every icy road; increase it as conditions require.
Avoid cruise control on slippery surfaces. Give snowplows room and avoid passing into a cloud of blowing snow.
NHTSA’s winter-driving guidance emphasizes slower speeds, increased stopping space and room around snowplows.
What Does Black Ice Do?
Black ice is a thin layer of ice that can be difficult to distinguish from wet pavement. It sharply reduces traction, sometimes before the driver realizes the surface has changed.
Be particularly cautious on bridges, shaded stretches and roads affected by melting and refreezing. Do not brake sharply or make sudden steering movements to “test” a suspected icy patch.
What If the Car Starts Sliding or Spinning?
Ease off the accelerator and look toward the path you want to take. Steer smoothly toward that path without abrupt overcorrection.
If emergency braking is necessary in a vehicle with ABS, use firm, continuous brake pressure rather than pumping the pedal. Learn your vehicle’s instructions before the trip.
Do not deliberately perform donuts on public roads. A clear-looking area may conceal people, curbs or parked vehicles, and losing control can happen quickly.
If Visibility Becomes Too Poor to Continue
Seek a safe exit, rest area or other place fully clear of moving traffic before conditions become unmanageable. Avoid stopping in a travel lane.
If you cannot reach a safe location, contact emergency assistance and follow local instructions. Your position relative to traffic matters as much as the weather outside.
What If You Get a Flat Tire in the Snow?
Do not make roadside tire replacement the automatic choice. Traffic, ice, poor visibility and an unstable surface can make changing a wheel dangerous.
- Slow smoothly and reach the safest available stopping place.
- Switch on appropriate warning lights and assess your surroundings.
- Call roadside assistance and describe the road, visibility and exact location.
- Tell the dispatcher whether you have a usable spare and wheel-lock key.
- Follow responder instructions about where occupants should wait.
Do not crawl beneath the car, jack it on snow or soft ground, or stand beside fast-moving traffic to inspect a tire. If the location presents immediate danger, contact emergency services.
Storms can delay roadside help, and service availability depends on local conditions and plan terms. Do not assume a membership guarantees an immediate response.
What to Do If You Become Stranded
Call for help, share your location and explain any medical needs. Staying with the vehicle is generally safer than walking into a snowstorm, unless the vehicle’s location creates an immediate danger.
Put on warm layers early and use blankets. Avoid exhausting yourself by repeatedly pushing the car or shoveling heavy snow.
Using the Engine for Heat
The National Weather Service’s emergency guidance suggests running the engine for about 10 minutes per hour, keeping the exhaust clear and opening a window slightly.
These precautions do not guarantee protection from carbon monoxide. Snow can block the exhaust again, and fumes may enter through leaks or surrounding conditions. Do not sleep with a combustion engine running. If you suspect exposure, seek fresh air and emergency help.
Hybrids may start their engines automatically while switched on. EVs require a plan for remaining charge and heat, even though a battery-electric vehicle has no tailpipe exhaust.
If the Wheels Spin but the Car Will Not Move
Stop prolonged spinning. It can dig the tires deeper and create additional problems.
If conditions are safe, clear snow around the tires and use suitable traction material. Follow the manufacturer’s instructions for snow modes or temporary traction-control settings. Do not use an improvised tow strap or an unsuitable attachment point.
If recovery would expose you to traffic or extreme weather, wait for qualified help.
Frequently Asked Questions
Is it okay to drive while it is snowing?
Sometimes, but snowfall alone does not answer the question. Check visibility, ice, wind, road maintenance and official advice. Postpone nonessential travel when conditions are dangerous.
What is the worst car to drive in snow?
A vehicle with unsuitable or worn tires, poor visibility or unresolved faults is a poor choice regardless of brand. Low clearance and performance-oriented summer tires can add limitations. Evaluate the actual vehicle and conditions.
Is a heavier car safer in snow?
Weight alone does not guarantee safety. It affects vehicle behavior, but traction, tires, speed and handling remain critical. Do not add unsecured weight as a winter-driving shortcut.
What wind speed can flip a car?
There is no universal threshold. Vehicle height and shape, gust direction, speed, terrain and road conditions all matter. High-profile vehicles and trailers can be particularly vulnerable. Follow wind-related travel restrictions instead of relying on a single number.
What color car is safest in snow?
Do not choose a snowstorm travel plan around paint color. Clear working lights, appropriate lighting use, visibility, speed and road conditions are more useful considerations.
Should I buy winter wipers before every storm?
No. Check whether your existing blades clear the glass properly and remain suitable for the conditions. Replace damaged or ineffective blades; dedicated winter designs are useful for some drivers but are not automatically required.
Will AAA bring fuel or jump-start the car during a snowstorm?
Those services may be available under your membership, but conditions, access and local operations affect response. Confirm the request and expected assistance rather than assuming immediate arrival.
See AAA fuel delivery and AAA jump-start service.

Make the Decision Before You Reach the Storm
Check the route, tires, visibility, energy reserve and supplies before leaving. Resolve known vehicle problems and keep an alternative plan if conditions worsen.
Postponing a trip can be the most effective safety decision you make. Preparation gives you more options; it does not remove the limits imposed by ice, wind and poor visibility.
