Local records
Find the correct custodian
Chicago publishes a traffic-crash dataset, but a dataset is not a complete incident file. Reports, video, roadway, transit, maintenance, medical, and witness records should be tracked separately.
Preserve photographs, video, reports, vehicle details, and witness information.
Log insurance communications and avoid guessing about speed, fault, or injuries.
02
Records and physical evidence
Crash and incident reports
Original scene and vehicle files
Medical and expense records
Insurance correspondence
Vehicle repairs, downloads, nearby video, witness memory, and roadway conditions can change. Preserve first; avoid destructive inspection or unsupported fault statements.
03
People, organizations, and insurance
Drivers, passengers, vehicle owners, employers, police agencies, road authorities, repairers, insurers, camera owners, and medical providers may each hold a different part of the record.
Identify liability, collision, comprehensive, medical-payments or personal-injury-protection, uninsured/underinsured, health, disability, and employer-related coverage without assuming each applies.
04
Questions for an Injury Law Firm
Which people, companies, vehicles, or public bodies may hold evidence?
What deadlines and insurance rules apply in the relevant state?
