Bill would increase fine for not using 4×4 on Waipio Valley Road

Waipio Valley Road descends 900 feet in less than a mile and has an average grade of 25 percent, though some areas are steeper. Rep. Mark Nakashima (D-Hamakua, Hilo) has introduced a House bill that would assess a $250 fine for using any vehicle other than a low-grade, four-wheel-drive vehicle to traverse the access road between the lookout and valley floor.
