Yes they can. Motorists have an elevated duty of care towards those who share the roads with them. They have a responsibility to be careful with pedestrians or cyclists nearby. However, pedestrians have responsibilities too. For instance, pedestrians are expected to use crosswalks and wait for walk signals before proceeding.
We had a case once where our client jaywalked across the street and as a result, the insurance company found the client 50% responsible for the accident – and they weren’t wrong.
However, just because you’re partially at fault for an accident in Illinois, does not mean that you are barred from recovering. Illinois is a comparative negligence state which means that as long as you are not more than 50% at fault for an accident, you can still recover at least a portion of your damages.
