What is the purpose of the 3-second rule?

To determine the maximum speed allowed To maintain a safe following distance in traffic To time how long a green light lasts To assess how quickly to stop in an emergency

Correct Answer:

To maintain a safe following distance in traffic

Explanation:

The purpose of the 3-second rule is to maintain a safe following distance while driving in traffic. This rule helps drivers gauge the distance between their vehicle and the one in front of them to ensure they have ample time to react in case the vehicle ahead suddenly stops or slows down. By counting seconds from when the rear of the vehicle in front passes a fixed point until your vehicle reaches that same point, you can assess if you are a safe distance away. This practice reduces the risk of rear-end collisions and promotes safer driving behaviors, especially in varying traffic conditions.
