While driving behind a vehicle on a road that is slippery and wet, what time gap should you leave between their car and yours?
Three seconds
Four seconds
Two seconds
Explanation: You should apply the four-second rule when it's wet, frosty or when you are towing a trailer. The four-second rule means that you leave four seconds between you and the vehicle in front. It gives you more time to react and more time to stop.
