Fatal crashes on I-40 in Arizona
Every fatal crash NHTSA coded to Interstate 40, also written as Noncard, Purple Heart Trl, in Arizona, 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.

138fatal crashes over five years · 164 deaths
Over 2020 to 2024, NHTSA recorded 138 fatal crashes on I-40 in Arizona, in which 164 people died. That is 2% of the 5,558 fatal crashes recorded in Arizona in those years, about 28 a year. 4 of the 138 were coded to a ramp, frontage or service road of I-40 rather than the main lanes. In 2024, the latest year, 33 were recorded.

Where on I-40: 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 138 fatal crashes NHTSA coded to I-40 in Arizona 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-40, 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-40 in Arizona is counted within Arizona 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 Arizona 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.
