A Federal Way woman is among two injured and one deceased in a car accident on Interstate 5 Wednesday morning.

According to Washington State Patrol, at approximately 2 a.m., a driver in a red 1998 Ford Expedition was heading southbound in a northbound HOV lane, approaching South Albro Place in Seattle. At the same time, a 29-year-old man from Seattle was driving a white 2013 Chevrolet Tri-Med ambulance in the HOV lane, correctly heading northbound, when the Ford struck the ambulance.

In the ambulance was a 40-year-old Federal Way woman and an 18-year-old man from Kent. The ambulance tried to swerve to avoid the Ford but the two collided. After the hit, the Ford came to a rest in the HOV lane while the ambulance stopped in the right shoulder.

The two Tri-Med employees and occupant of the ambulance were rushed the Harborview Medical Center while the driver of the Ford was pronounced deceased at the scene.

All lanes were blocked for four hours. Washington State Patrol is investigating the cause of the accident but believe the driver of the wrong way vehicle may have been impaired.

Just before the accident, Segeant Chong Yim of the Washington State Patrol saw the Ford travelling in the wrong direction and notified other troopers who tried to intercept the vehicle before the crash.

Troopers urge drivers to stay alert, look further ahead, always keep an escape route in mind in case you encounter a situation like this and drive sober.
