Upon demand by the inspectors all shipping papers, documents and records required to be kept by a person transporting fuel shall be produced for immediate inspection. The places where inspections may occur include, but are not limited to:
(5) A designated inspection site.
For purposes of this section, a "designated inspection site" means any state highway or waterway inspection station, weigh station, agricultural inspection station, mobile station, or other location designated by the director, either fixed or mobile.
