Quincy, WA (June 9, 2026) – The Washington State Patrol is investigating a two-vehicle collision that left three people injured on Monday afternoon, June 8, at about one mile east of Quincy.
The crash occurred at 2:31 p.m. at the intersection of State Route 28 and Road O Northwest. Investigators said a 1989 Peterbilt 377 truck was traveling south on Road O NW when it approached SR 28, while a Subaru Outback was traveling eastbound on SR 28.
Officials said the truck driver failed to yield at a stop sign and entered the intersection, where it struck the Subaru. The impact pushed the Subaru into an irrigation ditch, while the truck came to rest on the eastbound shoulder of SR 28.
Three occupants of the Subaru were injured. The driver was taken by ambulance to Quincy Hospital. Two passengers were also transported for treatment, including one to Central Washington Hospital and another to Quincy Hospital. A fourth passenger in the Subaru was uninjured, and the truck driver was uninjured.
Authorities confirmed all occupants were wearing seatbelts, and no drugs or alcohol were involved. Troopers are actively investigating the circumstances of the crash. We extend our thoughts to the injured and wish them a swift recovery.
What Information Is Reviewed After an Intersection Truck Collision?
Intersection crashes involving commercial trucks are often reviewed by examining right-of-way rules, stop sign visibility, and driver awareness. Investigators may assess whether either driver had a clear line of sight before entering the intersection.
Speed, braking distance, and vehicle weight differences are also commonly considered, as larger trucks can take longer to stop once a hazard is identified. These factors can affect both impact force and crash severity.
Injury outcomes are often linked to seating position, vehicle type, and restraint use. Physical evidence such as skid marks, vehicle resting positions, and damage patterns can help reconstruct how the collision unfolded.
