The accident took place near the 21-mile marker, close to the exit for State Road 59. One of the drivers, Enver Jasarevic, 36, St. Louis, was trapped inside his vehicle when officials arrived.
Indiana State Police Trooper Bill Bradbury told The Brazil Times Jasarevic moved his vehicle into the left lane heading eastbound on I-70 to pass another semi-truck driven by Mikhail Agababov, 61, Beaverton, Ore.
However, Bradbury said Jasarevic moved back into the right lane.
When he did, Bradbury said Agababov had applied his brakes, resulting in the collision.
Jasarevic suffered lacerations to his face and complained of pain in one of his legs, but refused medical treatment at the scene, according to Bradbury.
"When I arrived, it looked a lot worse than it was," Bradbury said.
He said weather may have been a contributing factor to the accident.
"There's nothing criminal here," Bradbury said. "It's just an accident."
Jasarevic was hauling automotive oil treatments while Agababov was hauling metal pieces for store racks.
The accident took place close to 10:30 a.m. Debris from the accident was scattered across the eastbound lane of I-70 as traffic was backed up into Vigo County.
Also responding to the accident included officials with the Clay County Sheriff's Department, Clay County Search and Rescue, TransCare and the Posey Township Volunteer Fire Department.
After closing the portion of I-70 to clear debris, Brazil City officials arranged for stoplights along United States 40 to be placed on flashing yellow for motorists traveling east and west trying to get around the interstate.
According to the accident report, the vehicle driven by Jasarevic was totaled.
In addition, there was an estimated $5,000 in damages to Abababov's vehicle.
