What is the purpose of the "two-second rule" in driving?

Answer: B — To maintain a safe following distance from the vehicle ahead

The purpose of the "two-second rule" in driving is to maintain a safe following distance from the vehicle ahead. This rule is a guideline that helps drivers gauge an appropriate amount of space between their vehicle and the one in front, reducing the risk of rear-end collisions. By waiting a full two seconds from the moment the vehicle ahead passes a fixed object, such as a sign or tree, the driver can better ensure that they have enough time to react in the event of sudden stops or emergencies. This practice is especially important under varying weather conditions, heavier traffic, or when driving at higher speeds, as it allows for adequate reaction time to avoid accidents and enhances overall road safety.
