Leaving a distance of 60 meters (200 feet) between your vehicle and other commercial vehicles on the highway is important for several reasons. This distance provides adequate space for safe maneuvering, especially if the vehicle in front needed to brake suddenly. Commercial vehicles are larger and typically take longer to stop than passenger vehicles, so maintaining this distance helps to ensure that there is enough reaction time to avoid collisions. Additionally, this safe following distance improves overall traffic flow and reduces the risk of congestion, as it allows for smoother transitions in speed among larger vehicles.

Maintaining a proper following distance is also essential for visibility. A greater distance allows you to better anticipate situations that may arise ahead, such as obstacles or sudden stops. Furthermore, this space helps protect against the effect of wind turbulence created by larger trucks, which can destabilize smaller vehicles if they are too close.

The other options represent distances that are either insufficient or excessive for maintaining safety on the highway. 30 meters may be too close, especially in traffic situations where rapid stops are possible. Distances significantly greater than 60 meters, such as 75 meters, while safe, may lead to unnecessary gaps that can disrupt the flow of traffic. Thus, 60 meters is the recommended safe distance that balances safety
