3 killed in multi-vehicle crash; NB I-15 closed for several hours in Box Elder County

SOUTH WILLARD, Utah — Three people died Monday following a crash involving multiple vehicles on northbound Interstate 15.

Sgt. Cam Roden with the Utah Highway Patrol said a prior incident occurred near milepost 357, causing traffic to slow down in the area. A semi-truck was approaching the slower traffic near milepost 352 and was not able to stop before hitting a red passenger car. The car was then pushed into a van, while the semi continued, rear-ending a second semi before crashing into a third semi.

“A lot of people were stopped out of their cars, trying to help. Unfortunately, some of them were beyond help,” said UHP Lt. Bryce Kohler.

The driver of the first semi and the driver of the red passenger car died of their injuries on scene. The passenger of the red car was taken to the hospital, where they later died from their injuries.
