Two drivers were injured Thursday night in a five-vehicle crash on westbound Interstate 70 in Boone County.
According to initial reporting, the crash happened at about 9:35 p.m. on June 11, 2026, near the 121-mile marker of westbound I-70. The report states that four vehicles were stopped in the right lane within a construction zone while traffic was heavily congested due to a lane closure.
A 2026 Peterbilt 589 tractor trailer approached from behind and failed to properly observe the slow traffic ahead. The front of the Peterbilt struck the rear of a 2010 Toyota FJ Cruiser, pushing that vehicle into the rear of a 2021 Chevrolet Silverado. The Silverado was then pushed into a 2026 Mercedes Sprinter, which was pushed into a 2025 Honda CR-V.
The Toyota and Chevrolet drivers suffered moderate injuries and were transported to a local hospital. The semi truck, Toyota, and Chevrolet were totaled, while the Mercedes Sprinter and Honda CR-V sustained moderate damage.
Large commercial vehicles require extra caution because they need more time and distance to slow down, especially when traffic is stopped or congested. In this crash, law enforcement reported that the semi approached from the rear and failed to properly observe the slow traffic ahead in a construction zone. That kind of failure can turn ordinary congestion into a serious chain-reaction crash.
Semi-truck drivers, along with all others, have a responsibility to drive in a way that matches the conditions around them. When a construction zone, lane closure, or heavy backup is ahead, that means reducing speed, increasing following distance, and staying alert for stopped traffic. Work zones already place drivers in a more vulnerable position, and when a semi fails to adjust to those conditions, the consequences can be severe for everyone in its path.
