A driver of a fuel tanker died Friday after his truck crashed on Hawaii island.

The truck was traveling in the makai direction on Kawaihae Road when it ran off the highway and overturned between the 63-and 64-mile markers shortly after 2 p.m. Friday, police said.

Police said the driver was pinned inside the vehicle and died at the scene.

The cab of the truck separated from the frame of the vehicle and fuel was leaking from a broken pipe when firefighters arrived on scene, according to a Fire Department report.

About 1,900 gallons of diesel fuel spilled. A replacement tank transferred the remaining fuel from the overturned truck, police said. About 6,500 gallons of fuel was recovered.

Police withheld the identity of the driver pending positive identification and the notification of his family.

Both lanes of traffic were closed on Kawaihae Road for about 6 hours while the accident scene was cleared.
