Which of the following vehicles typically needs an ADP to operate airside?

Fuel trucks are required to have an Airside Driving Permit (ADP) because they operate in areas where aircraft are present and where strict safety regulations must be followed. These vehicles handle flammable materials and fuel, which pose significant safety risks in an airport environment. Proper training and certification through the ADP ensure that drivers are knowledgeable about the specific rules, safety protocols, and emergency procedures necessary for operating vehicles in these high-stakes areas.

In contrast, while rental cars, tour buses, and public transport buses may operate on airport property, they do not typically require an ADP for airside operation. These vehicles usually remain in designated areas where the risk of interaction with aircraft and fuel hazards is minimized, thus not subjecting drivers to the same comprehensive training requirements as vehicles handling hazardous materials like fuel trucks.
