Most deer-vehicle accidents (DVAs) occur during the months of October, November and December. Another peak occurs in May and June as one-year old deer are dispersing to new areas. However, DVAs can happen at any time of year. Deer are crepuscular, meaning that they are active at dawn and dusk. Thus, it is not surprising that most accidents involving deer happen between the hours of 5 to 10 p.m. and 5 to 8 a.m. While not all deer-vehicle collisions can be prevented, there are steps that drivers can take to avoid an accident.
