When following behind a commercial vehicle, how many seconds of following distance should be between you and the truck?

Maintaining a following distance of 4 seconds behind a commercial vehicle is crucial for several safety reasons. Commercial vehicles, such as trucks and buses, are significantly larger and heavier than passenger vehicles. This size difference means they require a longer distance to stop safely, especially in emergencies. A 4-second gap allows for increased reaction time and braking distance, providing a buffer in case the commercial vehicle suddenly stops or slows down.

Additionally, the 4-second rule helps ensure that the driver has a clear view of the road ahead. Following so closely behind a large truck can obstruct your line of sight, making it difficult to see traffic signals, obstacles, and road conditions. By maintaining a greater distance, you can better assess your surroundings and react appropriately.

This following distance also gives other road users the space they need to merge or change lanes safely without endangering the vehicles involved. Overall, prioritizing a longer following distance enhances safety for everyone on the road.
