How many seconds should a vehicle follow another vehicle at night for safe stopping distances?

• A. 4 seconds
• B. 5 seconds
• C. 6 seconds
• D. 7 seconds

Answer: (C)

The recommended safe following distance at night is typically around 6 seconds. This extended distance is crucial because visibility is reduced at night, which can affect reaction times and the ability to see potential hazards. At higher speeds, the stopping distance increases, meaning a greater following distance allows for more time to react to unexpected situations, such as sudden stops by the vehicle ahead or obstacles in the roadway. In contrast, shorter following distances may not provide adequate time to stop safely under these reduced visibility conditions, increasing the risk of collisions. The 6-second rule ensures that the driver has a buffer to gauge the distance required for braking effectively, enhancing overall safety.
