Three semis were involved in a chain reaction accident on I-84 early Friday morning as black ice covered sections of the freeway. At approximately 3:15 a.m., near milepost 21, a red Peterbuilt semi truck pulling a tanker trailer jackknifed and then struck a Conway semi truck pulling a single trailer.
According to a report from the Utah Highway Patrol, both semis were near the emergency lane when a CRST semi pulling a box trailer lost control on the slick road and also jackknifed, hitting the tanker truck.
Four Tremonton ambulances were responded to the scene. The driver of the Conway truck, a 34-year-old male from Salt Lake City, was transported to Bear River Valley Hospital with facial and head injuries. He was later transferred to McKay-Dee Hospital in Ogden.
The 67-year-old female driver of the tanker suffered chest injuries and was also transported to BRV Hospital and then taken by ground ambulance to McKay-Dee. Her 59-year-old husband, who was in the sleeper at the time of the accident, was transported by helicopter from the Tremonton hospital with chest and back injuries.
A 49-year-old male in the sleeper of the CRST truck was also transferred from BRV Hospital to McKay-Dee with a back injury. The driver of that truck, a 52-year-old-male from Virginia, was treated and released.
About 45 minutes later, at 4 a.m., a black SUV from Washington came upon the scene at a speed too fast for conditions and slid into a Box Elder County Sheriff’s vehicle. The deputy was assisting the UHP with the accident and was not in the truck at the time. No one was injured in that accident, although both vehicles sustained excessive damage.
The outside lane was closed for approximately four hours while crews cleaned up the wreckage.
