The heaviest snowfall was in the Brigham City and Perry area, according to a report from the Utah Highway Patrol. Many drivers failed to slow down in the adverse conditions and a total of 29 vehicles, including three semi trucks, were involved in 10 different accidents between mm 361 and 362, northbound I-15. Four of those crashes resulted in injuries.
The first happened about 8:30 a.m., when a box semi and two passenger cars lost control and crashed near the 362 exit. Then a four-car crash occurred just south of the first, followed by a six-vehicle crash involving a tanker truck and pup trailer. The driver of a tan Honda Accord, a 29-year-old female for West Haven, in that crash had to be extricated and was taken to Brigham City Community Hospital in serious condition with multiple broken bones.
Several other two and three vehicle crashes were also reported, along with a jackknifed semi at mm 361.
Traffic was rerouted onto SR-89 through Perry the rest of the morning until noon.
Further up the freeway, near Tremonton, a southbound driver lost control of his vehicle, drifted into the median and then slid into the northbound side guard rail. The driver backed onto I-15, panicked in the oncoming traffic, again spun out of control into the median and hit the guardrail a second time.
In a snowy Sardine Canyon, troopers responded to two more crashes, one at 9:30 a.m., and the second at about 10:30 a.m.
