What is the purpose of the two-second rule?

• A. To allow time for distractions
• B. To maintain a safe following distance between vehicles
• C. To measure speed when overtaking
• D. To decide when to change lanes

Answer: (B)

The two-second rule is an important guideline for maintaining a safe following distance between vehicles. This rule helps drivers ensure they have enough time to react if the vehicle in front of them suddenly stops or encounters an emergency. By providing a clear and measurable distance, drivers can gauge how far behind they should be to minimize the risk of rear-end collisions.

To apply the two-second rule, a driver should select a fixed point on the road, such as a sign or a tree, and count the seconds it takes for their vehicle to reach that point after the vehicle ahead passes it. If they reach the point in less than two seconds, they are following too closely and should increase the distance.

Establishing a safe space between vehicles allows for better reaction times and contributes to overall road safety, making it a fundamental aspect of defensive driving practices.
