What is the recommended following distance for trucks on highways?

The recommended following distance for trucks on highways is four seconds or more under favorable conditions. This guideline allows truck drivers to have a safer stopping distance due to the larger size and weight of their vehicles compared to standard vehicles. A four-second following distance provides ample time for the driver to react to sudden changes in traffic conditions or emergencies ahead, reducing the likelihood of collisions.

In addition, maintaining a longer following distance is particularly crucial for trucks because they require more time and distance to stop safely than smaller vehicles. This becomes even more important when considering factors such as road conditions, weather, and load weight. By keeping a four-second gap or more, truck drivers can better ensure they have enough space and time to safely maneuver their vehicle, which is especially critical given the potential hazards of highway driving.
