The passenger killed in Thursday’s fatal crash near Portland International Airport is identified as Jamie R. Pallviny-Brown, 43. Her family has been notified of her death.

The investigation reveals that she was in the passenger seat of a 1995 Ford Mustang convertible (photo) when it crashed into a Freightliner tractor with a box trailer. Evidence at the scene indicates the Mustang was traveling west on Northeast Cornfoot Road at a high rate of speed and collided with the broadside of the trailer, in front of the rear wheels, as it was pulling out of a driveway. The Mustang went under the trailer and came out the other side.

The passenger of the Mustang was pronounced dead at the scene and the driver of the Mustang, a 56-year old male, was transported to an area hospital with serious injuries. UPDATE: Passenger Killed in Crash Near PDX Identified (Photo)

Because the bottom of a truck is higher than the bumper of passenger vehicles, when there is a collision the smaller vehicle easily slides under the truck and the first point of impact is the windshield. Seatbelts, airbags, and car crumple zones do not function as intended in underride crashes —front, side, and rear — leaving passenger vehicle occupants vulnerable to life-threatening injuries.

Note: In order to raise awareness and preserve the memories of underride victims — precious ones gone too soon — I have been writing memorial posts on what appear to me to be underride crashes. I am not a crash reconstructionist, and I do not have all the facts on these crashes; but I think that underride should be investigated as a potential factor in truck crash injuries and deaths.
