During deer season, which generally runs from October through December, there is a dramatic increase in the movement of the deer population. Many of these deer find their way onto highways and into suburban neighborhoods. As a result, more deer-vehicle collisions occur in this period than at any other time of year.
According to the Insurance Institute for Highway Safety from 1975 to the mid-2000s there was a general upward trend in deaths from collisions with animals. However, this trend has leveled off in the past few years. There were 211 deaths from collisions with animals in 2017, these deaths occurred most often during July-September.
According to State Farm, between July 1, 2018 and June 30, 2019 one out of every 116 drivers had an insurance claim from hitting an animal. These claims were most likely in West Virginia, with one in 38 people making an insurance claim based on this kind of accident. In Hawaii, the odds are 1 in 731, making it the lowest risk state for animal collisions.
