The clocks have been set back to winter, there is frost on the lawn nearly every morning, and it’s only a matter of days before we wake up and see that first snowfall. You’ll know it when it happens; it’s when you hear the screaming and laughter of the neighborhood kids as they dive into their first snowball fight, signaling that winter is officially here. Every year we celebrate the change of seasons, and it seems that every year we need to relearn how to drive in the snow. Without fail, the first storm sends a car or two off the road.
It seems that it takes a fender bender to wake drivers up, refreshing their memories to, “Oh yeah, it’s snowing, I need to slow down.” Have you ever noticed that the majority of these “victims” are driving 4-wheel or all-wheel drive vehicles? Fact: 4-wheel or all-wheel drive does not mean you are invincible.
In reality, 4x4 does nothing for winter driving other than to get the vehicle moving. If you are stuck in a drift, or you need to get up your driveway before you snow blow, 4x4 can help. Once you are underway, it does nothing. In fact, most all-wheel drive systems disengage once slippage stops, or when the vehicle reaches a certain rate of speed. Once the vehicle is underway, it’s your tires and your driving habits that keep you on the road.
Quality tread, deep and wide enough to grab the snow and throw it away is what gives you traction in snow. Also, tires made of proper winter rubber that is designed to grip the road in low temperatures helps to keep you on the road. The rubber of summer tires is too brittle to adhere to cold, slippery surfaces, proving down right dangerous in winter conditions.
However, nothing helps more with the challenges of winter driving than just slowing down. Whether you are driving with rear wheel, front wheel, 4x4, or all-wheel drive, the vehicle’s ability to stop is determined by its weight in relation to its brakes, not by how the wheels are driven.
Basic physics: an object in motion wants to stay in motion, especially if it’s on ice and snow. In the best of conditions, a heavy full size SUV with extra weight and momentum will take longer to stop than a small car. In winter conditions, the stopping distance is even longer, with an even higher risk of slipping. Of course if it’s icy, even the best studded tires may not help. If you are going too fast for conditions, you will crash. Slow down, and at least you have a chance of avoiding a problem. I for one can’t wait to drive in the snow again. This will be my first winter with an all-wheel drive vehicle, the Toyota RAV4. Even though I won’t be invincible, I still look forward to enjoying the artificial safety and security of a vehicle with higher clearance and all-wheel drive. Regardless, I will slow down when the snow flies. You should too!
