In the latest statistics released April 2019, the Illinois Department of Transportation reported that the statewide number of auto accident fatalities rose 8 percent for the second year in a row, while miles driven rose less than 2 percent. The nationwide rise in fatal crashes has been linked to higher highway speed limits, and this is somewhat borne out by Illinois statistics. Controlled-access, interstate-type highways saw a 16% jump in fatalities from 2015 to 2016, while state routes saw a 32% leap.
However, the rise in fatalities was offset by a significant reduction in A-injury accidents, defined as an incapacitating injury such as severe cuts, broken bones, head injuries, and internal injuries. While the total number of fatalities rose from 998 to 1,078, an increase of 8 percent, the total number of A-injuries dropped from 10,078 to 9.060, a decline of 10 percent.
In Cook County alone, there were 255 fatal accidents and 3,170 A-injury accidents. Will County saw 42 fatal crashes and 427 A-injury crashes in 2016.
