Winter Roads Bring Hazards—But Do You Know the Real Risks?

As temperatures drop and roads turn slick, many drivers may feel confident they know how to handle winter conditions. But how well do you understand the facts behind safe cold-weather driving? With winter storms and icy mornings already settling in across much of the country, now is the time to separate myth from truth.

To help drivers prepare, we’re sharing three common statements about winter driving. Test your knowledge—then read on to see what experts say.

Statement 1: There’s no real benefit to warming up the engine by idling before setting out.
True. While many drivers believe idling helps their car “warm up,” this advice is outdated. According to the U.S. Department of Energy, modern vehicles no longer require extended idling to start. Older cars with carburetors required a warm-up to function properly. But today’s engines are fuel-injected and electronically controlled. In fact, prolonged idling can waste fuel, increase emissions, and damage engine components over time. Experts recommend letting your engine idle for just 30 seconds before gently driving off.

Statement 2: If you have good winter tires, your braking distance remains virtually the same regardless of the road conditions.
False. Even the best winter tires can’t defy the laws of physics. According to Transport Canada and the National Safety Council, winter tires are designed to grip cold, icy, and snowy roads better than all-season tires—but they don’t eliminate danger. Braking distances on ice or packed snow can be up to 20 times longer than on dry roads. That means leaving extra space between your car and the vehicle ahead, especially when roads are slick, is a must.

Statement 3: Putting heavy objects in the trunk of your vehicle helps maintain better traction on slippery roads.
False. This was once common advice when rear-wheel-drive cars were more prevalent. Adding weight over the rear axle improved traction. But today, most passenger vehicles are front- or all-wheel drive, where rear weight doesn’t help and can actually affect balance and handling. Instead of throwing in sandbags or other heavy items, focus on tire condition and proper inflation. Ensure your vehicle’s weight is evenly distributed and that your traction control system is working properly.

As winters become less predictable due to climate shifts, understanding proper cold-weather driving techniques is more important than ever. Sudden temperature swings, freezing rain, and snow squalls can create dangerous conditions within minutes.

“Winter driving requires more than just good tires,” says Michelle Anderson, a certified driving instructor in Michigan. “It’s about planning, reducing your speed, and staying alert. Many crashes can be avoided if drivers respect winter’s challenges.”

Before the next snowfall, take a few steps to prepare. Make sure your vehicle is winter-ready with a battery check, proper tire pressure, windshield washer fluid that won’t freeze, and a working heater and defroster. And don’t forget your emergency kit: blankets, gloves, a flashlight, a small shovel, and non-perishable snacks can make all the difference if you get stranded.

Most importantly, slow down. No matter how experienced you are, driving too fast in winter conditions is never worth the risk.
