What should an operator always do before operating a vehicle on the airside?

Conducting a pre-operational safety check is crucial before operating a vehicle on the airside because it ensures the safety of both the operator and other personnel in the busy airport environment. This check typically includes inspecting the vehicle's brakes, lights, tires, and other critical systems to confirm that they are functioning properly. By identifying any mechanical issues beforehand, the operator helps prevent accidents or malfunctions that could lead to injuries or damage, thereby maintaining a safe operational environment.

While reviewing the vehicle's aesthetic condition may provide insight into the overall upkeep of the vehicle, it does not address its functional capability. Checking the fuel level is important for ensuring the vehicle can operate, but it is just one part of the overall safety assessment. Obtaining permission from a supervisor is also necessary in certain situations, but it does not replace the fundamental requirement of a safety check, which is integral to safe vehicle operation on the airside.
