Crash Reports

IDOT uses motor vehicle crash information for a number of critical services including, crash data analyses, safety program design, and roadway engineering design with the ultimate goal of preventing fatalities or injuries on Illinois roadways. Illinois statute (625 ILCS 5/11-408) requires that crash reports be submitted to the Department "...within 10 days after investigation of the motor vehicle accident." In addition to crash reporting, IDOT collects and compiles data for the Traffic and Pedestrian Stop Study.

Motorists

Under a recent change to Illinois Statute, completion of the Illinois Motorist Report is no longer a requirement. Based on Public Act 102-0560, a motorist involved in a motor vehicle crash will not need to fill out an SR1B Illinois Motorist Report and send it to the Illinois Department of Transportation. However, pursuant to State Rules, any employee involved in a crash in a state vehicle, is STILL required to file this report with IDOT’s Bureau of Data Collection, please send a request for a copy of the Illinois Motorist Report to DOT.CrashForms@illinois.gov
