What indicates vehicle traffic lanes on the airfield?

The use of solid white lines on the edges and a dashed white center line is standard practice for indicating vehicle traffic lanes on an airfield. The solid white lines signify the boundaries of the lane, guiding vehicles to remain within designated areas without crossing over into adjacent lanes. The dashed white center line allows for the possibility of changing lanes or passing, indicating to drivers where such maneuvers can be safely performed.

In airfield operations, clear delineation of traffic lanes is essential for maintaining safety and order among various types of vehicles, including maintenance trucks, security vehicles, and other ground support equipment. This visual guidance helps prevent collisions and ensures that vehicles navigate the airfield in a structured manner.

The other options do not serve this purpose: dashed yellow lines typically indicate caution areas or potential hazards, solid red lines may be used to indicate restricted areas, and blue painted arrows are often utilized to indicate parking spaces or specific directions but do not define traffic lanes. Thus, the solid white lines and dashed white center line are important for establishing clear traffic patterns and enhancing safety on the airfield.
