MERIDIAN -- Idaho State Police now say at least 44 vehicles were involved in a massive pileup Thursday on Interstate 84 west of Boise.
Officers say speed was a contributing factor in the crash, and have cited several drivers for traveling too fast for the conditions.
The situation unfolded as a wall of fog lowered visibility, causing a chain reaction of crashes that blocked the westbound lanes of I-84 in Meridian for nearly five hours. Ten victims were taken to area hospitals with various injuries. Amazingly, all survived.
Authorities have divided the massive crash into 12 separate accidents for investigation purposes.
The most serious involved a 2004 Kenworth logging truck that crashed into "many vehicles" as it tried to stop in the fog, according to state police.
One of the those vehicles was a 2011 Subaru Forester driven by a 52-year-old man from Meridian. Police say the man's SUV was pinned underneath the logging truck and dragged down the freeway.
Photos of the Subaru Forester showed it barely recognizable in the wake of the crash. Rescuers worked for more than an hour to free the man from inside the wreckage. He was rushed to Saint Alphonsus Regional Medical Center in Boise, and was listed in serious condition Friday morning.
Emergency responders who spoke to KTVB say they had never witnessed a crash like this before. They include veteran police officers and firefighters who described the scene as chaos.
The Idaho State Police were assisted by Nampa Fire Department, Meridian Fire Department, Ada County Paramedics, Canyon County Paramedics, Ada County Sheriff's Office and the Idaho Department of Transportation.
At one point, traffic on I-84 heading west was backed up for close to two miles.
