Many drivers know that they need to watch for deer on the roadways during the late fall. What isn't as well known is that drivers need to be watchful during this time of year as well. Deer-vehicle collisions increase during the spring fawning period, late-May to early-July (June peak). This is due, in part, to does driving away their prior year's young before giving birth to this year's fawns. These young deer relocate to unfamiliar areas and are not yet familiar with the intricacies of crossing roads. Additionally, does are frequently involved in spring accidents due to their loss of agility in later stages of pregnancy.
The Illinois Department of Natural Resources recommends that drivers be aware of locations (segments of roadway) where deer are seen regularly. As they approach these areas, motorists should slow down, and be extra vigilant for deer attempting to cross roadways. Typically, if you see one deer... there will be more.
