What is the acceptable action regarding illuminated red runway stop bars during runway inspections?

Illuminated red runway stop bars indicate that vehicle operators must stop and not proceed onto the runway. This is a critical safety measure designed to prevent conflict between vehicles and aircraft, ensuring that the runway is clear before allowing any access. During runway inspections, the red stop bars remain an essential signal to maintain an organized and safe airfield environment.

Crossing red stop bars, regardless of the circumstances, could lead to potential accidents, compromising the safety of aircraft operations. Therefore, it is never acceptable to cross illuminated red runway stop bars. Adhering to this rule is vital for the safety of all airport operations.
