A two-car accident shut down Highway 525 for about one hour Monday and resulted in a Clinton man being sent to the hospital for minor injuries.

The accident occurred at about 5:15 p.m. near Useless Bay Road. Clinton resident Sean Humphrey, 28, was southbound in a 1990 Subaru Legacy and was slowing to make a left turn onto Newman Road when his vehicle was struck from behind.

The violent collision sent Humphrey’s car spinning and flipped the other vehicle, a 2011 Toyota RAV4 driven by Clinton resident John Bertrand, 52, onto its roof.

Humphrey said later the collision was a bit of a blur.

“I remember the glass shattering and spinning,” he said.

Humphrey suffered cuts to his face, and other motorists attended to Bertrand, helping him from the overturned vehicle.

“He looked to be OK,” Humphrey said.

Bertrand was taken to Whidbey General Hospital for minor injuries, according to Trooper Chris Merwin with the Washington State Patrol.

“He fell asleep at the wheel,” said Merwin, of Bertrand.

He was cited for “negligent driving in the second degree,” which is the standard charge for falling asleep while driving, Merwin said.

Drugs or alcohol are not suspected factors in the crash, he said.

The collision resulted in the closure of both lanes of traffic on Highway 525, detouring traffic along Double Bluff and Newman roads, for about one hour.

According to Merwin, both vehicles were totaled.
