A semi carrying a propane tank crashed south of Loon Lake on Saturday morning, requiring several nearby residents to shelter in place in case of an explosion, Washington State Patrol spokesman Jeff Sevigney said.

Around 10 a.m. on Sunset Bay Road, about a mile south of Loon Lake, a semi-truck driver failed to stop as two vehicles were turning, Sevigney said.

The truck swerved, clipping two cars, and rolled into a ditch, Sevigney said. The semi driver had minor injuries and occupants of the other involved cars reported no injuries, he said.

A “loaded” propane tank on the semi was leaking in the ditch, Sevigney said.

Highway 395 in the Sunset Bay area was shut down for several hours Saturday afternoon.
