State troopers and Mason County deputies responded to the scene, about one mile north of Shelton along Highway 3, at about 10:30 a.m. Tuesday after receiving a report that a car had rolled off the highway and down a steep bank onto the shore of Oakland Bay.
Two injured people, both men in their 20s or early 30s, were found at the accident scene, which would could only be reached by boat.
A preliminary investigation by the Washington State Patrol found that the two men were in the black Honda SUV when the driver attempted a U-turn on the highway. He accidentally backed off the embankment, slamming into the beach about 90 feet below, said WSP Trooper Russ Winger.
The male passenger used a cell phone to call 911 to report the accident.
The injured men were taken by boat to a more accessible area. The driver was airlifted to Harborview with serious injuries and the passenger was transported to Mason General in Shelton with non-life-threatening injuries.
