When can a vehicle cross an illuminated Runway Stop Bar?

A vehicle should never cross an illuminated Runway Stop Bar, as this indicates that the runway is active and that there is a risk of collision with aircraft. The illuminated lights serve as a crucial safety measure to prevent vehicles from entering a runway inappropriately.

Crossing an illuminated Runway Stop Bar can compromise both vehicle and aircraft safety, making it imperative that operators respect this signage at all times. Awareness and adherence to these safety protocols help maintain orderly and secure operations on the airside of the airport, especially in high-traffic environments such as YVR.
