Winter Driving Hazards: What You Need to Know Before You Hit the Road This Season

By LaSalle County Emergency Management Agency

As winter approaches, our county begins preparing for the challenges that snow, ice, and extreme cold can bring. While our highway department and sheriff’s office both play critical roles in keeping residents safe, every driver also has a personal responsibility to be ready for winter travel. Whether you’re commuting to work, heading out for holiday travel, or taking a long-distance road trip, winter conditions can change rapidly — and preparation can make all the difference.

Below are key winter driving hazards we see each year, steps you can take before traveling, and guidance on what to do if you become stranded.

Common Winter Driving Hazards

❄️ Snow and Ice on Roadways

Snowfall can reduce visibility and traction, while ice — especially black ice — can be nearly invisible. Bridges, overpasses, and shaded roadways freeze first and thaw last. Many winter crashes occur when drivers don’t realize how slick the road has become until it’s too late.

🌬️ Reduced Visibility

Blowing and drifting snow can quickly cover road markings or obscure other vehicles. Whiteout conditions may develop suddenly during strong wind events or lake-effect snow bands.

🧊 Freezing Rain

Freezing rain creates a glaze of ice on roads, signs, and power lines. Even four-wheel-drive vehicles struggle to maintain traction on ice. When freezing rain is forecast, consider altering or delaying travel if possible.

🚘 Cold Weather Car Trouble

Cold temperatures strain vehicle batteries, reduce tire pressure, and thicken engine fluids — all of which can lead to breakdowns at the worst possible time.

Preparing for Winter Road Trips

1. Check the Weather Before You Go

Always review the forecast along your entire route, not just your destination. Monitor alerts from the National Weather Service and be aware of winter storm watches, warnings, and advisories. If conditions look hazardous, delay travel until conditions improve.

2. Prepare Your Vehicle

A well-maintained vehicle is essential for safe winter travel. Before winter sets in, make sure to:

• Inspect your tires for tread depth and proper inflation

• Ensure your battery is in good condition

• Keep at least half a tank of fuel

• Check your wiper blades and fill the windshield washer reservoir with winter-grade fluid

• Confirm your defroster and heater are working properly

• Carry tire chains if recommended for your travel in the region you are visiting

3. Pack a Winter Emergency Kit

Your vehicle should be stocked with supplies in case conditions deteriorate or you become stranded. Consider including:

• Blanket or sleeping bag

• Extra warm clothing, gloves, and hats

• Ice scraper and snow brush

• Jumper cables

• Flashlight with extra batteries

• First aid kit

• Sand, kitty litter, or traction mats

• Small shovel

• Non-perishable snacks and bottled water

• Portable phone charger

• Reflective triangles or flares

4. Plan Your Route

Let someone know where you are going, when you’re leaving, and when you expect to arrive. Stick to main roads that are more likely to be plowed and treated.

5. Drive Smart

• Slow down — speed should match conditions

• Increase following distance to 8–10 seconds

• Avoid sudden braking or sharp steering

• Use low beams in heavy snow

• Never use cruise control in winter conditions

What to Do if You Become Stranded

Even with the best preparation, winter storms can still cause road closures, collisions, or immobilized vehicles. If you find yourself stranded:

🚗 Stay With Your Vehicle

Your vehicle provides shelter and makes it easier for responders to locate you. Only leave if you can clearly see a nearby building and conditions are safe.

📞 Call for Help

Dial 911 if you are in immediate danger. Otherwise, notify roadside assistance, local law enforcement, or family members. Provide your location, direction of travel, and vehicle description.

🧣 Conserve Heat and Fuel

Run your engine for short intervals — about 10 minutes every hour — to stay warm. Keep a window cracked to prevent carbon monoxide buildup, and make sure your exhaust pipe is clear of snow.

🔦 Stay Visible

Turn on hazard lights and utilize reflective roadside triangles to warn approaching vehicles to your vehicle being stranded .

❄️ Stay Hydrated and Warm

Layer clothing, use blankets, and move your arms and legs periodically to maintain circulation.

🚧 Avoid Overexertion

Shoveling heavy snow in extreme cold can lead to exhaustion, injury, or cardiac events. Clear only what you need for safety — such as clearing around the tailpipe — and rest frequently.

Final Thoughts

Winter driving requires patience, preparation, and awareness. By taking a few simple steps now, you can reduce your risk and ensure a safer journey for you and your family. Our county agencies will continue doing everything we can to keep roads safe, but it takes all of us working together to get through the winter season safely.
