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

Answer: B — To maintain a safe following distance

The purpose of the "two-second rule" is to maintain a safe following distance between your vehicle and the one in front of you. This rule encourages drivers to keep a distance that allows for safe stopping and reaction times. By counting two seconds from the time the vehicle ahead passes a fixed point, such as a sign or tree, a driver can gauge if they are following too closely. If the driver reaches the fixed point before the count of two seconds is complete, it indicates that they are too close and should increase their following distance. This practice contributes significantly to road safety by reducing the likelihood of rear-end collisions, particularly in situations where sudden stops are necessary.
