What is the recommended distance to maintain between commercial motor vehicles traveling in the same direction on a highway?

The recommended distance to maintain between commercial motor vehicles traveling in the same direction on a highway is 60 metres (200 ft). This distance is advised to ensure safe following distances that allow sufficient time and space in case of sudden stops or emergencies.

Maintaining this distance provides a buffer that helps prevent collisions, especially considering the longer stopping distances required by larger vehicles due to their mass. Additionally, it helps drivers in the vehicles behind have adequate visibility of the road ahead, allowing for better decision-making while driving. Proper spacing is also crucial for fuel efficiency and overall road safety, as it decreases the likelihood of chain reaction accidents in dense traffic situations.

The other distances presented, though they may seem adequate, do not align with the established guidelines for maintaining a safe following distance in commercial transportation.
