A traffic fatality is under investigation on Interstate 96 in Livingston County, the Michigan State Police reported. 

The crash happened about 9:30 a.m. along westbound I-96 near Kensington Road/Exit 151 in Brighton Township. 

Troopers say a 19-year-old Detroit man was driving a 2023 Chevrolet Malibu westbound on I-96 and exceeding speeds of 100 miles per hour when he swerved into the middle lane and struck another vehicle. Both drivers then lost control and struck a third vehicle, which caused the Malibu to overturn and hit a construction traffic trailer, according to police. 

The driver of the Malibu was killed. A second driver involved in the crash suffered minor injuries. 

MSP says two other passengers — a 19-year-old Detroit man and a 19-year-old West Bloomfield man — were also in the Malibu. It is unclear if they were injured. 

An investigation is ongoing, but police believe speed was a factor in the crash. It is unknown if drugs or alcohol were factors in the crash, troopers said. 

All lanes of westbound I-96 are blocked starting at Milford Road in Oakland County, according to traffic reports from the Michigan Department of Transportation. The posted detour is southbound on Milford Road / Exit 155B, westbound on Grand River, northbound on Kensington Road, then back to westbound I-96.
