SNOHOMISH — An Everett woman suffered life-threatening injuries Thursday morning after her vehicle collided with a dump truck on Highway 9 outside of Snohomish.
Highway 9 just south of U.S. 2 was shut down for about three hours while state troopers investigated the crash and collected evidence.
The woman, 39, was in a Chevy Tahoe heading northbound when she reportedly rear-ended a white pickup, Washington State Patrol trooper Keith Leary said. Most of the vehicles there at the time had stopped or slowed because of traffic congestion.
The pickup was pushed into the back of a Volkswagen Jetta.
The impact of the initial collision sent the Tahoe into the path of an oncoming dump truck and trailer carrying a load of sand and gravel. The dump truck driver tried to avoid the collision, but jackknifed and struck the woman’s vehicle, Leary said.
The woman suffered serious head injuries, and medics rushed her to Providence Regional Medical Center Everett. A medical helicopter was unavailable because of weather conditions.
The dump truck driver, 47, of Arlington, was not injured. The other two drivers were taken to a local hospital with minor injuries.
The crash remained under investigation Thursday night, Leary said.
“We are still investigating why the driver did not see the cars ahead,” he said.
