Which vehicles can operate outside the Vehicle Standard Requirements (VSRs) on Apron 1?

Emergency and airport maintenance vehicles are permitted to operate outside the Vehicle Standard Requirements (VSRs) on Apron 1 because their primary function is to ensure the safety, security, and functionality of airport operations. These vehicles are essential for responding rapidly to emergencies, conducting repairs, and maintaining critical airport infrastructure. The nature of their work often requires flexibility regarding standard vehicle requirements, allowing them to navigate specific areas of the apron where other vehicles may not be authorized.

In contrast, private transport vehicles, visitor vehicles, and fuel delivery vehicles are typically subject to the VSRs to ensure compliance with safety and regulatory standards. These vehicles are not engaged in the immediate support of airport operations at the same level as emergency and maintenance vehicles, thus they must adhere to stricter operational guidelines.
