When you're following another car, you have to adjust your following distance depending on the conditions. And on a perfect day, it's four seconds behind. On a rainy day, four seconds behind. But if you're driving on icy roads, you need about seven to eight seconds between cars, because the worse the conditions are, the more stopping distance your vehicle requires. And what that means is when the back end of the car in front of you passes a stationary object, you start counting. And if the front end of your car reaches the same object before you count to seven, you're too close and you need to open up more space because you need more stopping distance on icy roads.
