What is the recommended following distance under normal driving conditions?

• A. At least 1 second behind the vehicle in front
• B. At least 2 seconds behind the vehicle in front
• C. At least 3 seconds behind the vehicle in front
• D. At least 5 seconds behind the vehicle in front

Answer: (C)

The recommended following distance under normal driving conditions is at least 3 seconds behind the vehicle in front. This recommendation is based on the need for a safe buffer that allows drivers to react in various scenarios, including sudden stops by the vehicle ahead, changes in traffic flow, and adverse weather conditions. A 3-second gap provides enough time for a driver to comprehend a situation and apply the brakes if necessary. This distance accounts not only for the speed of the vehicles but also for the stopping distance required under normal conditions. As speed increases, the distance traveled in that time frame also increases, necessitating a longer following distance to maintain effective control and safety. In contrast, shorter distances like 1 or 2 seconds may not provide sufficient reaction time, especially in unexpected situations. A following distance of 5 seconds is excessive for normal driving conditions and may lead to unnecessary congestion in moderate traffic scenarios. Thus, the 3-second rule strikes an optimum balance between safety and practicality on the road.
