When does the two-second rule apply while driving in fast traffic?

Explanation: In good dry conditions, you should leave a two-second gap between your vehicle and the one ahead. When the weather is bad, you'll have to keep a greater distance, because it will take you longer to stop. In wet weather it will take up to twice the distance; in icy weather this could increase to ten times as far.
