ROCKFORD (WIFR) -- It happened just before 4:30 p.m. Authorities with the Illinois State Police say traffic was heavy heading eastbound on I-90, when a semi truck failed to slow down, swerved into the left lane to try to avoid hitting cars and hit another semi. That's when the truck flipped and three vehicles caught fire.
"One of that saddle tanks on the passenger side of that truck tractor, came off, spilling diesel fuel. That saddle tanks hit into both of the vans that were directly in front of the semi that was struck; as a result the semi that rolled and the mini vans all became fully engulfed," explains MSgt. Edward Petrik with the Illinois State Police, District 15.
The driver of the semi that flipped was taken to the hospital with neck and back pain. The driver of the first semi truck and the nine adults in the two minivans, were not seriously injured.
