Highway 19 was closed near Kolekole Bridge on Sunday after a naked man was struck by a pickup truck.
The man, identified in a police log as 35-year-old Ryan Laudan, was reportedly hitting vehicles traveling on the highway near Kolekole Beach Park moments before.
Police received reports of a “nude pedestrian in the middle of the highway” who was “hitting and kicking cars” at 7:11 p.m., according to a police spokeswoman.
Officers were en route when Laudan was hit by the truck.
The collision caused the highway to be closed for about 30 minutes, police said.
Laudan of Kalaoa was transported to Hilo Medical Center before being airlifted to Queen’s Medical Center in stable but serious condition.
His status was unclear Monday.
The spokeswoman said it’s not known why he was nude and in the highway or if he was camping at the park.
The incident is being treated as a negligent injury case.
