How are Vehicle Service Roads (VSRs) indicated on aprons?

Vehicle Service Roads (VSRs) on aprons are indicated by two solid white lines, with a single broken white center line. This marking system is crucial as it provides clear visual guidance for vehicle operators, ensuring that they maintain proper navigation and adhere to safety protocols while operating on airside surfaces.

The two solid white lines establish the boundaries of the VSR, indicating that vehicles should not cross these lines. The presence of the single broken white center line allows for a visual indication that traffic can move in both directions, providing flexibility for vehicles while still maintaining a safe separation from other areas. This dual line system is essential for the safe and efficient movement of vehicles on the apron, especially in busy airport environments, where maintaining defined paths is critical for avoiding accidents and ensuring operational effectiveness.
