KINGSPORT, Tenn. (WJHL) — Three people were injured in a multi-vehicle pileup that shut down Interstate 81 North in Sullivan County on Thursday, according to the Tennessee Highway Patrol.

The crash happened around 2:30 p.m. just before Exit 66.

According to a preliminary crash report, the crash happened as traffic was slowed for an uninvolved tractor-trailer that was being towed away.

A Freightliner tractor-trailer was unable to slow down for the slowed traffic and struck four other vehicles: an International truck, a Ford Explorer, a Toyota Highlander, and a Dodge Caravan, according to the report. The Dodge Caravan was then forced into the rear of a Chevrolet Silverado.

A total of six vehicles were involved.

Two passengers in the Dodge Caravan, a two-year-old and one-year-old, and the driver of the Chevrolet Silverado were listed as injured in the report. The extent of their injuries is unclear.

Charges are pending against the driver of the Freightliner, according to the report.

The crash caused delays on I-81 North and on State Routes 75 and 126 near Blountville as traffic was diverted off the interstate.
