(1) Interest and penalties for delinquent payments of road use assessment fees payable pursuant to the provisions of ORS 818.225 and of single-trip nondivisible load permits shall be calculated in the same manner that interest and penalties are calculated under ORS 825.490 and 825.494.
(2) An audit conducted by the Department of Transportation pursuant to its authority under this chapter may include an examination of records of the carrier pertaining to the road use assessment fee imposed under ORS 818.225.
