Notes:
1 The category of "Unknown" represents all values that were invalid entries, values recorded as "unknown,"
or when no values were entered for the field.
2 Effective January 1, 2009, the legal reporting threshold for traffic crashes involving only property damage increased from $500 to $1,500 when all drivers are insured. However, if any driver does not have insurance, the threshold remains $500 (Illinois Traffic Crash Report SR 1050: Instruction manual, p.6).
