When following a truck on a rural highway in rainy conditions, what is the minimum following distance required?

The correct answer emphasizes the importance of maintaining a safe following distance, especially when driving in challenging conditions such as rain. A following distance of at least 6 seconds is recommended in these circumstances to allow for adequate reaction time and to compensate for reduced traction on wet roads.

When following large vehicles like trucks, it is crucial to account for their longer stopping distances and potential obstructions they may encounter. The 6-second rule provides a buffer that allows drivers sufficient time to react in case the vehicle in front has to slow down or stop suddenly. In rainy conditions, road visibility and traction are compromised, making it even more important to give yourself more time to react. This practice aligns with defensive driving principles, ensuring safety for both the driver and others on the road.
