Authorities in rural Michigan say a pickup truck ran a stop sign and collided with a van carrying members of a local Amish community, resulting in at least six fatalities.

The crash happened Tuesday afternoon in Gilford Township, about 100 miles north of Detroit. According to the sheriff’s office, 13 people were involved — 10 of them in the van. Several passengers from both vehicles were ejected during the collision.

Seven people were transported to the hospital, though their conditions have not yet been released. The Amish passengers had been traveling with a hired driver, a common practice since Amish communities typically do not operate motor vehicles.

In a separate incident the same day in western Michigan, state police reported that a 4-month-old girl died after a crash involving an Amish buggy and a pickup truck. Other children and adults in the buggy were injured, including a 2-year-old boy in critical condition.

Police urged drivers to use extra caution in areas where horse-and-buggy travel is common.

Amish communities are primarily located in Ohio, Pennsylvania, and Indiana, but Michigan is also home to a significant population.
