Police have charged a University of Maine student in a hit-and-run collision involving a car and a horse-drawn buggy in northern Maine. Troopers said Tuesday that they had charged Brandon Clark, 20, of Fort Fairfield with leaving the scene of an accident, driving to endanger, failure to maintain control, and failure to use caution when passing an animal. Department of Public Safety spokesman Steve McCausland said Clark’s car struck the southbound buggy on Route 1A in Easton Monday afternoon. The buggy was pushed to the side of the road and destroyed. A 16-year-old boy operating the buggy was thrown off, but neither he nor the horse was injured.
