Fatal crashes on I-80 in Illinois
Every fatal crash NHTSA coded to Interstate 80 in Illinois, 2020 to 2024, with the year, the county and what the record says about each. Fatal crashes only, and a count, not a rate: the federal record has no traffic volume for a road.

Where on I-80: by county, 2020 to 2024
The counties the crashes were coded to, alphabetical. A road’s count in a county depends on how many miles of it run there and how busy they are; the page does not rank the counties. Each name opens the county page with its own rate.
What the record says about those crashes, 2020 to 2024
Every figure is a count of the 66 fatal crashes NHTSA coded to I-80 in Illinois over five years, from the fields FARS records. Nothing is estimated or inferred.

Road type is FARS FUNC_SYS for the crash, which can differ from the route’s class where a crash was coded on a frontage road or ramp; speeding is any vehicle coded SPEEDREL 2 to 5; drinking is any driver coded DRINKING = 1 (police-reported, not a blood-alcohol test).
How this is counted
- The road is the designation FARS wrote. Each crash in NHTSA’s Fatality Analysis Reporting System names the trafficway it was on (
TWAY_ID) and, at an intersection, a second one (TWAY_ID2). NHTSA standardises the route designation (I-45,US-59,SR-6) and the police often add a local name after it (I-45/NORTH FWY) or a ramp or frontage word. The page counts every crash whose designation is I-80, once, whatever followed it. Nothing else is matched: a crash coded only to a local street name is not here even if that street is this road. - Same number, another state, another road. I-80 in Illinois is counted within Illinois only. Where the route continues into a neighbouring state it has its own page there, and a State Route number means nothing outside its state.
- Only roads with ten or more fatal crashes over 2020 to 2024 have a page. Fewer is too few to say anything, and the county page already lists the most-named roads in each county as the police wrote them.
- No rate, no rank. The Illinois page lists every numbered road in route order with its count and nothing else. Roads with more lanes, more miles or more traffic record more fatal crashes; the record cannot separate those from the road’s design.
