As days shorten and the breeding season for deer approaches, the chance of encountering deer on roadways increases significantly. Deer-vehicle accidents can be minimized by practicing defensive driving. Nearly 50 percent of all vehicle accidents involving white-tailed deer occur between October and December, according to Patrick Mayer of the DNR Division of Fish & Wildlife. Knowing the following information and practicing defensive driving will help reduce your chances of becoming a deer-vehicle collision statistic. Deer are most active between sunset and sunrise, deer travel in groups, be careful in areas where you have seen a deer before, if you see a deer slow down, use caution near hills or blind turns, never swerve to avoid a deer and pay attention to deer crossing signs.
