The Montana Highway Patrol responded to a series of crashes Sunday morning on I-90 between Lockwood and Hardin.
From just after 6 a.m. to just before 9 a.m., nine crashes were recorded on the Montana Highway Patrol's incident website for that area. Most of the crashes occurred in the eastbound lane.
The Montana Department of Transportation's website showed that stretch of road as covered in ice and black ice, with scattered snow and ice down to the Wyoming border.
Trooper Benjamin Kecskes of the Montana Highway Patrol responded to a semitrailer that had crashed and reportedly was on fire at about 6:45 a.m. There was no sign of an actual fire at the scene, Kecskes said.
"As I was responding to that, a second semi crashed in front of me," the trooper said. "While I was checking on the driver from the first semi crash, two passenger vehicles crashed into each other immediately next to us."
None of the three incidents resulted in injuries. But the second semitrailer blocked the passing lane and almost completely blocked the driving lane, Kecskes said.
Two other troopers were dispatched to help handle the multiple crashes, he said, along with two Yellowstone County sheriff's deputies and the Worden Fire Department.
"We had many slide-offs and there were several other rollovers and actual crashes in the area," Kecskes said. "The main cause appeared to be people driving too fast for the conditions."
By about 9 a.m., after some of the major blockage was cleared up, traffic flow began to return to normal, he said.
