What does a solid white center line indicate in vehicle traffic lanes?

A solid white center line in vehicle traffic lanes serves to delineate the direction of traffic. It indicates that vehicles should stay to one side of the line, ensuring that traffic flows in an organized manner and helps prevent collisions. In an airfield context, this is crucial for maintaining safety as it guides drivers in navigating taxiways and other areas where directional traffic rules are essential.

The presence of this solid line helps reinforce the expectation of maintaining a specific direction of travel, which is vital in busy airfield environments where multiple vehicles may be operating near active runways and taxiways. Understanding this line's significance promotes safe driving practices, as it clearly informs drivers about the intended flow of traffic.
