The traffic-heavy counties of Cook and Madison led the state for the number of crashes, with 428 apiece. The counties with the most accidents after Cook and Madison are: Will (401 crashes); Sangamon (394); Fulton (350); Peoria (340); Lake (324); Kane (319); Rock Island (290) and Jackson (288).
IDOT offers the following tips to avoid deer collisions:
-
Reduce your speed near water, farm fields, and wooded areas; be prepared to stop.
-
Deer will often cross roads and double back; make sure deer have moved away from the road before proceeding.
-
If you see one deer, be aware that others may be close behind.
-
Alert other motorists to the presence of deer by tapping your brakes.
-
Don’t swerve into traffic or off the road if you see a deer; instead, slow to a stop.
