Whether you venture to the ski slopes once in a blue moon or spend six months of every year in snowy climes, we’ve assembled a few crucial points to remember while braving snow-covered roads. Follow these tips, and you might even look forward to cold weather driving.
Slow, Turn, Go!
Dynamically speaking, a car can only do three things: accelerate, turn and brake. While it’s possible to combine those commands from the behind the wheel, vehicles are far easier to control when those actions are performed separately. Let’s say you’re approaching a sharp bend on a snowy road: first, gently apply the brakes in advance of the turn. After taking your foot off the brake, coast through the corner while turning the wheel. Only after you’ve exited the turn and straightened the steering wheel, gently accelerate. “As easy as that sounds intellectually, it’s really hard for most people to put into practice,” says Jessica Guffey, Principal of the Accredited Driving School.
Limit Your Speed, and Think Ahead
Excessive speed is the single biggest reason people lose control in the snow, and slowing down will give you enough wiggle room to correct your course in case your vehicle loses control. “It takes 4 to 10 times longer to stop in ice and snow,” explains Guffey. “Adjust your speed to the conditions,” she adds, “but also remember that going too slow can be just as problematic as going too fast.”
If You Start to Slide…
… don’t panic! A proper response will ensure that car control is regained. If the vehicle oversteers (i.e., the back end swings out), accelerate lightly in order to transfer weight to the rear and increase traction. It may feel counterintuitive to press the gas pedal while a car is sliding, but that action can straighten out the tail-happy yawing motion. Conversely, if the car understeers (i.e., slides forward without turning), straightening the steering and gently touching the brakes will shift more weight over the front wheels and enable the tires to “bite” again. As with all winter driving maneuvers, using a gentle hand and not stabbing the gas, brake or steering wheel is the most effective way to recover from a slide.
Race drivers swear by smoothness when it comes to driving technique, and that practice becomes even more important in wintry conditions. “Pretend you’ve got a cup of coffee on the dashboard,” advises Chuck Good, Principal / Instructor of Accredited Driving School. “If you make sudden or abrupt movements, you’ll go from grip to no grip very quickly.” On the other hand, “[smooth inputs] will help you sense the limits of your tire’s grip before your car starts to slide.”
Becoming familiar with your car’s handling dynamics will prepare you for the unexpected. When the going gets slippery, does your car understeer (plow forward), oversteer (fishtail) or drift sideways? Weight distribution, suspension and drivetrain setups (like front-, rear- or all-wheel drive) affects how your car reacts to adverse conditions. If you can’t attend a driving school and learn about vehicle dynamics from the pros, carefully explore your car’s limits in a safe area like an abandoned parking lot. Once your sense memory develops, you’ll be better prepared to handle a slide when it arrives unannounced.
Electronic aids like anti-lock brakes and traction control have done wonders for vehicle safety, but icy conditions can render those features useless. Once a tire loses its mechanical grip on a slick surface, all the high-tech gizmos in the world won’t stop that vehicle from spinning out of control. Avoid the inescapable laws of physics by keeping your speed reasonable and maintaining a safe distance from cars and objects around you.
A reliably running car can help avoid a world of complications in inclement weather. Make sure your tire pressure hasn’t dipped with the drop in ambient temperature, and your vehicle will be easier to control as a result. Install winter wiper blades in order to maximize visibility, and test your battery to make sure it can handle the challenges of cold weather cranking. Take care of your car, and it will take care of you.
