What is the minimum following distance you should maintain behind a large truck?

Maintaining a minimum following distance of 4 seconds behind a large truck is considered best practice for several important reasons. Large trucks have larger blind spots, which can impede their ability to see passenger vehicles. Additionally, trucks require a longer distance to stop safely due to their size and weight. By maintaining a 4-second gap, drivers provide themselves with ample time to react to any sudden changes, such as the truck braking or an obstacle appearing in the road.

This distance also allows for better visibility, as it enables the driver to see around the truck, including any approaching vehicles or potential hazards. In situations where road conditions are wet or icy, extending this following distance beyond 4 seconds can further enhance safety.

Other options may not provide adequate space to react, especially given these factors. Therefore, maintaining a 4-second following distance is crucial for safe driving practices around large trucks.
