State transportation and wildlife officials are warning Illinois drivers to watch for deer on the roads this fall, with peak mating season running through December.
The Illinois Department of Transportation and the Illinois Department of Natural Resources said deer are more active across the state during this period, increasing the chance of a collision at any time of day.
"Deer are on the move throughout the state, increasing your chances of encountering one at any time," Illinois Transportation Secretary Gia Biagi said. "Stay alert, even during routine trips and your daily commute. Following a few simple recommendations and rules can help you avoid a trip to the body shop – or worse."
Safety tips from IDOT and IDNR
The agencies' past safety guidance, according to IDOT's website, includes:
- Be aware of your surroundings, especially in areas with deer crossing signs.
- Scan the sides of the road for eye shine — the reflection of headlights in the deer's eyes.
- Slow down if you see a deer, because they travel in groups and more are likely nearby.
- Prepare for the unexpected, as a deer may stop in the middle of the road or double back.
- If a collision is unavoidable, don't veer. Try to glance your vehicle off the deer and avoid swerving into the opposite lanes or off the road.
IDOT says that if you hit a deer, you should pull off to the shoulder, turn on your hazard lights and call 911 to report the crash.
Background
According to IDOT data reported by WREX, Illinois recorded 14,436 crashes involving deer in 2024. Of those, 13,733 caused property or vehicle damage, 693 caused injuries and five were fatal. About 42% of deer crashes that year happened in October, November and December, with November the highest-risk month, accounting for 21% of all deer crashes, the station reported.
IDOT and IDNR have long noted that most deer crashes occur in rural areas and at twilight or nighttime, and that deer activity rises during the fall mating season.
