Show answer & explanation

Correct answer: A. By using a fixed point and applying the two second rule.

A driver can judge a safe distance from the vehicle in front by using the two second rule. This is measured by picking a fixed point. As the vehicle in front passes it, begin saying "only a fool breaks the two second rule". If you pass the fixed point before you have finished the phrase, then your vehicle is too close, safely slow and increase your distance from the vehicle in front.
