Two people were seriously injured following multiple crashes involving tractor-trailers early Friday morning in Saline County, Arkansas. The first crash occurred around 1:30 a.m. when a semitrailer overturned on Interstate 30 westbound, leading to a second 18-wheeler colliding with the overturned truck. Shortly after, another crash took place nearby when a tractor-trailer struck a pickup truck, pushing it into a separate semitrailer. An additional 18-wheeler then hit a semitrailer and overturned, leaving that driver injured.
