What is the recommended following distance behind another vehicle?

1. At least one second

2. At least two seconds

3. At least three seconds

4. At least four seconds

The correct answer is: At least two seconds

The recommended following distance behind another vehicle is at least two seconds. This practice allows for a safe buffer between vehicles, which is especially important for reacting to sudden stops or emergencies. The two-second rule provides enough time to assess the road ahead and adapt to changing traffic conditions, enhancing overall road safety. To measure this distance, one can observe a stationary object on the side of the road when the vehicle in front passes it; if the driver reaches the same object before counting to two, it indicates that they are following too closely. Maintaining this distance helps in avoiding rear-end collisions and gives drivers adequate time to apply brakes or maneuver if necessary. Longer distances may be advisable under certain conditions, such as poor weather or heavy traffic, but two seconds is generally the standard recommended distance for safe driving in typical circumstances.
