When should you use the two-second rule?

Explanation: Use the two-second rule when conditions are good and you're driving on roads carrying faster-moving traffic. Choose a fixed reference point, and when the vehicle ahead passes that point say to yourself 'Only a fool breaks the two-second rule.' If you reach the object before you finish saying this, you're too close and you need to drop back and check again.
