Deer-vehicle collisions are especially common in fall and winter, resulting in over 150 deaths and tens of thousands of injuries annually in the US. Michigan is among the top 10 states for such accidents due to growing deer populations and urban development displacing deer habitats. Drivers should be vigilant in early morning and evening when deer are most active, slow down if deer are spotted, brake firmly if a collision is unavoidable, and always wear a seatbelt in case of impact.
