Where the Crash Happened: Northbound I-15 South of Hidden Valley Pkwy

How Vehicle Size Differences Affect Interstate Collisions
A box truck and a passenger SUV differ in weight, height, visibility, and braking characteristics. Those differences can influence the force of an impact and where each vehicle travels afterward, particularly on a multilane interstate.
In this crash, the box truck and Porsche ended up on opposite sides of I-15. Investigators can use the damage and final vehicle positions to determine how the contact occurred and whether either vehicle changed lanes or moved across the roadway after impact.
How This Crash Is Investigated
CHP investigators may document the damage to both vehicles, debris, tire marks, lane positions, and the locations where the truck and Porsche came to rest. The rear damage reported on the Porsche may help establish the direction and point of contact.
Driver statements and any available witness or vehicle data may be compared with the physical evidence. The dispatch log does not establish responsibility, and the completed investigation may provide details that were unavailable during the initial response.
