Portions of the video have been cut to help protect the privacy of those involved.*** The video indicates possible contributing factors including (1) slick road surfaces from rain earlier in the evening, (2) a possible overcorrection or loss of traction on the vehicle, (3) an abrupt move into the lane by another driver who continued to drive on (4) velocity of the vehicle faster than the cars around it (5) lack of attenuation at the sound wall barrier, though wall is significant set back from roadway (6) potential for “underride” when striking the rear of the DOT vehicle. (7) The Nissan Versa was tested for small overlap front crash protection starting in 2014; in that model year, it received a poor rating on that crash test. (8) The velocity and sharp angle at which it struck the truck and sound barrier. Per State Patrol: "DOT trucks were doing debris clean up southbound 35W at 50th St. DOT had emergency lights illuminated, and were on the right shoulder. Traffic was slowing, and merging left. The Nissan Versa overcorrects due to slowing traffic, loses control. Nissan goes back across slowed traffic. making impact with the DOT truck, and then the concrete sound wall. Injury type: Fatal"
