When should you use the ‘two-second rule’?

Explanation: To check whether you've left a safe gap between your vehicle and the one ahead, choose a fixed reference point such as a bridge, sign or tree. When the vehicle in front passes the object, 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.
