TENINO, Thurston County, Wash., Oct. 9, 2026 — A two-vehicle crash shut down part of Old Highway 99 South at its intersection with SR-507 on Wednesday, October 7, according to the Thurston County Sheriff's Office. At least one person reported neck pain after an airbag deployed, authorities said.
The crash happened at the junction of Old Highway 99 South and SR-507, where deputies and South Thurston Fire & EMS responded to find a vehicle blocking the westbound lane. Crews worked to clear the roadway as traffic was affected in the area.
One patient was reported to be complaining of neck pain tied to airbag deployment during the crash.
The collision remains under review. We wish those injured a full recovery.
Airbag Deployment and Two-Vehicle Crashes: What the Numbers Show
According to the National Highway Traffic Safety Administration, 2,979 passenger-car occupants were killed in two-vehicle crashes involving a passenger car and a light truck in 2023. That figure reflects how often a mismatch in vehicle size and weight shapes the outcome when two vehicles collide, even in crashes where occupants survive with injuries like neck or back pain tied to airbag deployment.
Airbags are designed to reduce the risk of head and chest injuries during a sudden stop, but the force of deployment can itself cause strain injuries to the neck and upper body, especially in lower-speed intersection crashes. That is one reason emergency crews treat airbag-related complaints as something to evaluate on scene instead of dismissing as minor.
Intersections and junctions where a secondary road meets a state route, similar to where Old Highway 99 South meets SR-507, are common sites for two-vehicle crashes because of turning movements and crossing traffic patterns. National crash data consistently shows these junction points as a concentration area for collisions involving two vehicles.
Frequently Asked Questions
What should I do immediately after a car accident?
Move to a safe location if possible, call 911, and avoid moving anyone with a suspected neck or back injury until medical responders arrive. Exchange information with the other driver and document the scene if you're able.
Where do most traffic accidents happen?
A large share of crashes occur at or near intersections, where vehicles cross paths or change direction. Rural highway junctions and state route intersections see frequent collisions tied to turning and crossing traffic.
What injuries are most common in car accidents?
Neck and back strain, often linked to airbag deployment or sudden stops, are among the most frequently reported injuries, along with cuts, bruises, and head impacts. Some injuries, including whiplash, may not be immediately obvious and can take hours to appear.
What to Do After a Car Accident in Tenino, WA
Anyone involved in a crash in Tenino should seek a medical evaluation even if injuries seem minor at first, since strain injuries from airbag deployment or sudden impact can worsen over time. Get the responding agency's report number for your records and follow up with your insurer promptly.
If you were a passenger or witness, provide a statement to responding deputies while details are fresh. Keep copies of any medical paperwork and follow your provider's guidance on follow-up care, particularly for neck or back pain reported at the scene.
