GRAND RAPIDS, Mich. (WOOD) — Authorities in Michigan are urging drivers in the Upper Peninsula to stay vigilant to avoid collisions with moose.

The Michigan Department of Natural Resources reports that since 2021, there have been 60 incidents where moose have been fatally struck by vehicles in the U.P. These accidents predominantly occur during the summer and autumn, with the highest frequency in September and October, according to a DNR report.

One notable incident involved a female moose with twin calves, which was killed by a vehicle on U.S. 141 in Iron County, an area known for frequent moose sightings. Officials express concern that the death of the mother moose likely means her calves will struggle to survive without her.
