What Happened
A construction trailer carrying liquid tar came loose from the vehicle towing it and was left sitting in the travel lane of southbound US-131 north of the Cadillac rest area on Friday night, Aug. 28, 2026, where it was struck by two southbound vehicles, according to the Michigan State Police Cadillac Post. State police released details of the crash on Monday, Aug. 31, as reported by WDIV-TV (ClickOnDetroit), UpNorthLive and ABC12.
The crash happened at approximately 9:40 p.m. in Clam Lake Township, Wexford County, in an active construction zone where US-131 had been reduced to a single lane. According to state police, a vehicle driven by a 50-year-old California man and a vehicle driven by a 25-year-old Oscoda man both struck the trailer. No injuries were reported. Police said the trailer was displaying an illegal Texas license plate and that its vehicle identification number was obstructed and damaged, which has complicated efforts to trace its owner.
The collision caused significant damage to the newly constructed section of highway, state police said, and the roadway was closed for several hours while the trailer and the damaged vehicles were cleared. Lt. Ashley Miller of the Michigan State Police said that leaving a piece of equipment in the travel lane of a roadway poses a serious risk to motorists, according to UpNorthLive. Police said the unknown vehicle towing the trailer failed to properly secure it, and the investigation into that vehicle is ongoing. State police also distributed a photograph of the detached trailer sitting on the highway.

The Investigation: What Happens Next
The central question for investigators is not how the two cars came to hit the trailer — a large, unlit piece of equipment sitting in the only open lane of a nighttime work zone is a hazard by any measure — but who left it there. State police have said the trailer’s Texas plate was illegal and its VIN was obstructed and damaged, which removes the two quickest ways to identify an owner. That leaves investigators to work through other avenues: manufacturer markings and serial numbers on the trailer’s components, the type and source of the tar it carried, and any contractor activity in the area that used equipment of that kind.
Because the crash occurred in a construction zone, investigators will likely also look at whether the trailer belonged to a contractor working on the US-131 project or to an unrelated hauler passing through. Traffic cameras, rest-area surveillance and dash-camera footage from vehicles that passed through the zone shortly before 9:40 p.m. could show the trailer still attached to its tow vehicle. State police are asking anyone with information to contact the Cadillac Post.
If the towing vehicle and its driver are identified, potential consequences could range from civil-infraction citations for an unsecured load and improper registration to more serious charges, depending on what investigators find. Michigan law requires loads and towed equipment to be secured so they cannot come loose on the roadway. The Michigan Department of Transportation, which oversees the US-131 reconstruction, will also be assessing the cost of repairing the newly built pavement.
The Legal Picture
Q1. Who is responsible when a detached trailer causes a crash?
In general, a driver who fails to properly secure a trailer or load can be held responsible for a crash it causes, and if the trailer was being used for a business, the company that owns or operates it may be responsible as well. The difficulty in this case is identifying that party at all. Our overview of commercial vehicle and truck accident claims in Michigan explains how responsibility is assessed when commercial equipment is involved.
Q2. What happens to the drivers who hit the trailer if the owner is never found?
Michigan’s no-fault system means each driver’s own insurer handles vehicle damage under collision coverage (if they carry it) and any injury-related benefits, regardless of whether the trailer’s owner is identified. Uninsured-motorist coverage, if a driver has it, can sometimes apply to crashes caused by an unidentified vehicle, though policy terms vary. Our explainer on Michigan no-fault insurance describes how those coverages fit together.
Q3. Do work-zone rules change anything?
Michigan imposes enhanced penalties for certain violations in active work zones, and construction contractors have obligations for traffic control and safety within those zones. Whether any of those rules are relevant here depends on who owned the trailer and why it was in the zone — facts that are still under investigation.
This section describes Michigan law in general terms only. Nothing here assumes that any identified or unidentified person in this crash was at fault, and nothing here is legal advice about any specific situation.
This Stretch of Road
US-131 is the principal north–south freeway through the western Lower Peninsula, running from the Indiana line through Grand Rapids and Big Rapids to Cadillac, where it continues north as a two-lane highway toward Manton, Kalkaska and Petoskey. The stretch north of the Cadillac rest area in Clam Lake Township sits at the transition between the freeway section and the rural highway that continues north, and it carries heavy seasonal traffic bound for northern Michigan’s lakes and resort towns.
The Michigan Department of Transportation has been reconstructing portions of US-131 in the Cadillac area during the 2026 season, with lane reductions and single-lane configurations in the work zones. Single-lane work zones leave no room for drivers to maneuver around an unexpected obstacle, particularly at night, which is why state police emphasized the danger of equipment left in the travel lane. The Cadillac rest area, just south of the crash site, is a common stopping point for travelers on the route.
If You Saw This Crash
The Michigan State Police Cadillac Post is asking anyone who saw a vehicle towing a liquid-tar construction trailer on US-131 near Cadillac on the evening of Friday, Aug. 28, or who has dash-camera footage from the southbound work zone before about 9:40 p.m., to contact the post at 231-779-6040. Investigators are particularly interested in identifying the vehicle that was towing the trailer.
