What is the purpose of the "two-second rule" when following another vehicle?

The purpose of the "two-second rule" when following another vehicle is to maintain a safe following distance. This rule is designed to help drivers avoid collisions by ensuring they have enough time to react if the vehicle in front suddenly stops or slows down. By staying at least two seconds behind the vehicle ahead, you give yourself a buffer of time to assess the situation and make necessary adjustments to your speed. This practice takes into consideration visibility, road conditions, and vehicle speed, ultimately enhancing overall safety on the road.

The other choices do not align with the main intent of this driving principle. For example, rapid acceleration, aggressive driving, and judging the speed of another vehicle are not the focus of the two-second rule; instead, the rule emphasizes caution and safety by promoting a responsible distance that allows for proper reaction time.
