What must all vehicles have before operating airside?

All vehicles operating airside are required to have a valid Airside Vehicle Operator Permit (AVOP) and functioning safety equipment. The AVOP ensures that the driver has received the necessary training and comprehension of airside operational procedures, regulations, and safety protocols. This is crucial for maintaining safety in a busy airport environment where various aircraft and vehicles are present.

Additionally, having functioning safety equipment on the vehicle is essential for the protection of both the operator and others in the vicinity. Equipment such as seatbelts, lights, and other safety measures must be in working order to comply with safety regulations and to ensure effective emergency response if needed.

While the other options mention elements related to safety and training, they do not encompass the specific and mandatory requirements for vehicles operating in airside areas at airports.
