A 59-year-old truck driver from Rio Rancho, New Mexico was killed Thursday afternoon when his tractor-trailer slammed into the back of another semi on Interstate 80 in Jefferson County, Pennsylvania, and his Rottweiler fled into the woods before being found safe the next morning. Michael Rougier, a U.S. Army veteran who served for a decade, was pronounced dead at the scene after being ejected from his truck cab during the collision.
The crash happened around 3:59 p.m. Thursday on I-80 East near mile marker 74.3 in Union Township, according to exploreJefferson. Rougier was driving a Freightliner tractor-trailer eastbound when it struck the rear of a Peterbilt tractor-trailer driven by 49-year-old Jagjit Singh of Carteret, New Jersey, which had slowed for traffic conditions ahead, per details in an accident report from Grossman Law Offices. Pennsylvania State Police confirmed Singh was not injured in the crash, the station's report notes.
Jefferson County Coroner Greg Furlong said Rougier was pronounced dead at 4:35 p.m. from blunt force trauma sustained in the crash, as reported by Connect FM. Pennsylvania State Police, Jefferson County EMS, and the Brookville and Corsica fire departments all assisted at the scene, the same account notes.
Search for Missing Rottweiler Ends in Reunion
Rougier had been traveling with his Rottweiler, Diesel, at the time of the wreck, and the dog fled into a wooded area near the crash scene. Furlong and Jefferson County official Jason Stiver searched the area afterward but could not locate the dog Thursday, prompting the coroner's office to ask residents and motorists near I-80 mile marker 74 to watch for Diesel, who family members described as friendly and approachable.
Diesel was found safe the morning after the crash, allowing officials to arrange his reunion with Rougier's family, according to Ground News. Furlong had said the coroner's office hoped to locate Diesel and reunite him with the family, a goal that was ultimately realized.
Highway Closure and a History of Trouble at This Stretch
The crash forced PennDOT to close Interstate 80 eastbound between Exit 73 at Route 949 in Corsica and Exit 78 at Route 36/28 in Brookville. The eastbound lanes remained closed for several hours during the investigation and cleanup, per exploreJefferson's reporting.
This is not the first fatal rear-end crash tied to sudden slowdowns at this stretch of highway. The same section of I-80 East near mile marker 74 in Union Township was the site of another fatal rear-end crash in May 2022, when a 24-year-old driver died after striking a dump truck moving at 5 mph near a construction zone slowdown, according to GantNews.
A Corridor Heavy With Freight Traffic
PennDOT planning documents for the nearby I-80 North Fork Bridges project indicate that this stretch of Interstate 80 in Jefferson County carries roughly 30,900 vehicles daily, with heavy commercial truck traffic making up 44 percent of total volume. Statewide, PennDOT crash data showed more than 7,500 heavy tractor-trailer collisions in Pennsylvania in 2022, resulting in 110 fatalities — at the time the highest five-year fatality total involving commercial trucks in the Commonwealth, according to figures relayed by PhillyLaw.
Even so, overall Pennsylvania traffic fatalities dropped to 1,047 in 2025, down from 1,127 in 2024, marking the lowest annual traffic death total recorded in state history, PennDOT reported in May. The state also enacted Paul Miller's Law in June 2024, making handheld cellphone use and text messaging while driving a ticketable primary offense aimed at curbing distracted driving.
It remains unclear whether active construction, an earlier incident, mechanical failure, or distraction played any role in Thursday's collision, and whether Pennsylvania State Police's crash reconstruction unit will recommend any charges. Before his years driving trucks, Rougier drew national attention in December 2013 in Rio Rancho, New Mexico, when he publicly spoke out on behalf of his ninth-grade son after a teacher made controversial remarks about the student wearing a Santa Claus costume, according to CBS News.
