A Clinton man was transported to Harborview Medical Center in Seattle Thursday after sustaining injuries in a two-car collision on South Whidbey.

A hospital official confirmed Daniel Hutchinson, 57, was in satisfactory condition Friday morning.

According to the Washington State Patrol, the accident occurred at about 4 p.m. Julio Fernandez, 18 and also of Clinton, was southbound on Highway 525 in a 1997 Infiniti sedan when his car veered off the right shoulder about 100 feet before the intersection at Bayview Center, the shopping complex that includes The Goose Grocer and a Valero gas station.

Fernandez’s vehicle struck Hutchinson’s, a 1990s Geo, which was in the intersection and preparing to merge onto the state route.

The cause of the accident was unclear Thursday and remained under investigation, Trooper Chris Merwin said.

“It was probably inattention,” he speculated. “Speed was definitely a factor.”

The impact was so hard that both vehicles came to rest on the east side of the intersection. Hutchinson was extracted by South Whidbey Fire/EMS and Whidbey General Hospital first responders, and then transported by ambulance to Harborview, Merwin said.

Fernandez was not hurt.

The state trooper said alcohol or drugs were not factors in the crash.

The collision resulted in both lanes of traffic being shut down for about 50 minutes. Motorists were detoured to Howard and Bayview roads.
