Fall in Illinois brings high school football, changing leaves, and deer mating season. The Illinois Department of Transportation and the Illinois Department of Natural Resources are advising drivers to stay alert for deer, particularly at dawn and dusk through December.

"While your natural instinct is to steer quickly out of the way when you see a deer, remember to not veer suddenly because you could lose control of your vehicle and swerve into another lane or off the road," stated Illinois Transportation Secretary Omer Osman. "Always prepare for the unexpected. A deer might stop in the middle of the road or double back. They also frequently travel in groups so when you see one there likely are others nearby."

In 2022, there were 14,524 crashes involving deer in Illinois. Among these incidents, 13,892 resulted in property or vehicle damage, while 629 led to injuries. Four crashes were fatal.

Although collisions with deer can occur year-round, October through December is a particularly risky period. Last year saw over 40% of such accidents during these months, with November being especially hazardous. More than 70% happened in rural areas during twilight or nighttime.

Drivers are encouraged to follow safe driving tips during this season: remain aware of surroundings near deer crossing signs; scan roadsides for eye shine from headlights reflecting off deer's eyes; slow down if a deer is spotted and anticipate more may follow; prepare for sudden stops by deer on roads; avoid swerving if a collision seems unavoidable.

Deer can appear unexpectedly even in surprising environments. It's important to stay vigilant and cautious where they commonly travel.

The top ten counties for deer-related crashes last year included Cook (542), Madison (396), McHenry (351), Lake (350), Will (344), Peoria (323), Fulton (313), Kane (286), Sangamon (282), and Macoupin (271).

"Deer are a part of the Illinois landscape, and drivers should be mindful of their presence," said Natalie Phelps Finnie, Director of the Illinois Department of Natural Resources. "Drive cautiously this time of year, especially at dawn and dusk when deer are particularly active for the fall mating season."

If involved in an accident with a deer, drivers should pull over safely to the shoulder, activate hazard lights, and call 911 without exiting their vehicle to check on injured animals.
