The key to safe driving in snow is being smooth with the steering wheel, accelerator, and brakes. Jerky movements with the controls easily unstick tires that have a tenuous grip on the slippery road, so every turn of the wheel, push of the brakes, and movement of the throttle must be deliberate, gentle, and gradual.
The slipperier it gets, the farther down the road you should look—and think. Anticipate what you'll need to do next. Slow way down for turns. Allow double the stopping distance when the road is wet, triple on snow, and even more on ice. Driving carefully and safely takes extra concentration.
If you feel your car beginning to skid, always, always, look where you want to go—not where the car is heading at that precise moment. Let your peripheral vision take care of whatever you're trying to avoid.
Dont hit the breaks!
For a front-wheel skid—where the front tires lose grip and the car turns in a wider arc than you expect—ease off the gas. In a beat or two, the front tires should regain traction. Then aim where you want to go as your traction returns.
For a rear-wheel skid—where the rear tires lose traction and you feel yourself beginning to spin out—quickly turn the steering wheel in the same direction that the rear is sliding. If, say, the rear is swinging to the left, turn the wheel to the left. Ease off the accelerator and stay off the brakes. As the rear wheels regain traction, steer back in the original direction.
