Do not operate vehicles or equipment in the no-drive zone under the aircraft’s fuselage and wings. Loading/unloading of some containerized narrowbody aircraft may require vehicles or equipment to be operated between the inboard engine and fuselage; great care must be taken to avoid contact with the engine or fuselage.
Never back a vehicle toward an aircraft unless a marshaller is present and the view is clear. Be very careful near moving aircraft; they have the right-of-way.
