What Happened
A four-vehicle crash on Gratiot Avenue near 30 Mile Road in Lenox Township sent 10 people to area hospitals on Monday afternoon, Aug. 31, 2026, according to reporting by WDIV-TV (ClickOnDetroit) citing the Macomb County Sheriff’s Office. One of the injured was listed in critical condition.
The collision was reported at approximately 12:40 p.m. Deputies closed Gratiot Avenue in the area of the crash while emergency crews treated and transported the injured, and the road remained closed into Monday afternoon as investigators worked the scene, WDIV reported.
The Macomb County Sheriff’s Office Crash Team was activated to investigate the circumstances of the collision, according to WDIV. As of Monday evening, the sheriff’s office had not publicly released the types of vehicles involved, the ages of the people hurt, how the vehicles came together, or which hospitals received the injured. The sheriff’s office said additional information would be released as it became available.

The Investigation: What Happens Next
When a crash produces multiple serious injuries, the Macomb County Sheriff’s Office typically assigns its dedicated Crash Team rather than leaving the case with the responding road patrol deputies. That team’s work generally starts at the scene: documenting the final resting positions of the four vehicles, measuring skid and gouge marks, photographing the roadway, and collecting whatever physical evidence remains before the road can be reopened. The extended Monday-afternoon closure of Gratiot is consistent with that kind of scene processing.
The next phase usually moves indoors. Investigators commonly seek to download event data recorders from the vehicles involved, canvass nearby businesses along the Gratiot corridor for surveillance video, review any dash-camera footage from passing motorists, and interview the drivers and passengers once their medical condition allows. Toxicology results, if any are ordered, can take weeks to come back from the laboratory.
Because 10 people were hurt and one remains in critical condition, the case could be forwarded to the Macomb County Prosecutor’s Office for review once the investigation is complete. That is a routine step in serious-injury crashes and does not, by itself, indicate that any driver did anything wrong. No citations or charges had been announced as of this report, and the sheriff’s office has not described the sequence of events that led to the collision.
The Legal Picture
Q1. What insurance rules apply when four vehicles and 10 injured people are involved in a single Michigan crash?
Michigan is a no-fault state, which means each injured person’s own auto insurer (or, for passengers without their own policy, an insurer identified under Michigan’s priority rules) generally pays medical expenses and lost wages regardless of who caused the crash. In a multi-vehicle collision with many injured occupants, sorting out which policy is responsible for each person’s benefits can be one of the first practical hurdles. Our explainer on Michigan no-fault insurance walks through how those priority rules work.
Q2. Can an injured person pursue a claim beyond no-fault benefits?
Under Michigan law, a person who suffers a “serious impairment of body function” or permanent serious disfigurement may bring a claim against an at-fault driver for non-economic losses, and for excess economic losses beyond the no-fault caps. Whether that threshold is met depends on the medical evidence for each individual, not on the size of the crash.
Q3. Why does the vehicle type matter so much in a crash like this?
The sheriff’s office has not yet said what kinds of vehicles were involved. If a commercial vehicle turns out to have been part of the collision, federal motor carrier rules on driver hours, maintenance, and cargo securement can become part of the picture, along with the carrier’s insurance. Our overview of truck accident claims in Michigan explains how those cases differ from ordinary passenger-car collisions.

This Stretch of Road
Gratiot Avenue, carried as M-3 through much of Macomb County, is one of the county’s principal north–south arteries, running from Detroit’s east side through Roseville, Clinton Township, Chesterfield Township and New Baltimore before continuing north through Lenox Township toward Richmond. Near 30 Mile Road it passes through a mix of rural frontage, commercial parcels and the approaches to the village of New Haven and the city of Richmond, and it serves as the main connector between the county’s northern communities and the I-94 corridor.
Because it is a divided, multi-lane highway with a mix of high-speed through traffic and turning movements at side roads and driveways, the Gratiot corridor north of 26 Mile Road has been the site of a number of serious multi-vehicle crashes in recent years. A closure at 30 Mile Road on a weekday afternoon typically pushes traffic onto County Line Road, Church Road and the mile-road grid, and adds significant delay for drivers heading to and from Richmond and the New Haven area.
If You Saw This Crash
The Macomb County Sheriff’s Office Crash Team is handling this investigation. Anyone who witnessed the collision, who was traveling on Gratiot Avenue near 30 Mile Road around 12:40 p.m. Monday, or who may have dash-camera or business surveillance footage from that stretch of road is encouraged to contact the Macomb County Sheriff’s Office. Independent accounts and video are often the most useful pieces of evidence in reconstructing a multi-vehicle crash.
