Illinois: accident reporting rules
When you must report a car accident to police or the state, the damage threshold, and the deadline.
| Report required if there is | Death, injury, or over $1,500 damage ($500 if a driver is uninsured) |
|---|---|
| Deadline | 10 days |
'Immediately' usually means calling police from the scene. A police report does not always satisfy a separate DMV report. Your insurer also needs prompt notice under your policy.
