Four people were killed and 17 injured in a massive traffic accident along Interstate 96 near Webberville, Michigan — about 70 miles west of Detroit — late Saturday night.

Police said the deadly pileup happened just before midnight when a semi truck with a trailer approached stopped traffic on the freeway but was unable to stop in time. The truck went through several vehicles in the left lane.

The impact caused the truck and several of the vehicles to catch fire, police said.

Officials said about 15 vehicles were involved, including the truck.

The highway will remain closed in both directions until the investigation is complete and the debris is cleared.

Officials said traffic was stopped on I-96 for a short time before the crash so utility crews could work on power lines. Troopers were on their way to reopen the highway when the accident occurred.
