On March 29th at approximately 1:58 am the Oregon State Police was dispatched to a head-on motor vehicle crash on Interstate 5 just north of Kruse Way, involving a semi-truck and passenger car. This location is within the city limits of Lake Oswego. Preliminary investigation revealed that a black 2015 Mazda M6, operated by Sydney Lopez MARTINEZ, age 25, of Cornelius, was traveling southbound on Interstate 5 in the northbound lanes of travel. As MARTINEZ continued southbound, a white 2015 Volvo semi-truck and trailer, operated by James CROPPER, age 66, of Gervais was traveling northbound in the middle lane of travel. CROPPER observed the Mazda’s headlights coming directly at his truck and swerved to the right in an attempt to avoid a collision. While executing this avoidance maneuver, CROPPER sideswiped a red 2015 Freightliner semi-truck and trailer, operated by Victor AMARO, age 29, of California, in the right lane of travel. The Mazda continued past the Volvo semi-truck in the middle lane and collided with its left rear dual tires on the trailer, causing the axel to shift. The Mazda then struck a white 2014 Freightliner semi-truck and trailer, operated by Dilpreet SINGH, age 30, of California, head-on. The Mazda and Freightliner and trailer came to rest on the grassy shoulder. The operator of the Mazda was transported by air ambulance to Oregon Health and Science University in critical condition. It was determined that alcohol was a contributing factor. CROPPER, AMARO and SINGH were uninjured in the collision.
