Two Bremerton residents were killed in a traffic collision with a logging truck early Wednesday morning, the Washington State Patrol reported.

The crash occurred around 5:20 a.m. on State Route 101 in Mason County, just north of Shelton.

Stephen J. Jacobson, 65, was fatally injured as was a female passenger who has not been named. Mr. Jacobson’s family has been notified.

The collision occurred when a Kenworth logging truck collided with a four-door passenger car being driven by Mr. Jacobson, a WSP memo stated. According to Trooper Chelsea Hodgson:

“The passenger car was traveling NB on SR 101. The semi was traveling SB. It appears the passenger car crossed over the center line into the path of the semi.”

The cause remains under investigation, police said.

The truck driver, 44-year-old Todd E. Dewey, was not injured in the crash.

Dewey is a commercial truck driver who has been featured in multiple seasons of the reality TV series “Ice Road Truckers” on the History channel.

Dewey did not immediately respond to a request for comment.

Neither drugs nor alcohol were involved, police said, and no arrests were made. The road was closed for approximately five hours following the crash.
