Historical data: truck crashes in Idaho since the 1990s
Combines the FMCSA crash file (all reported truck crashes, real coverage from about 1990) with NHTSA FARS (fatal crashes involving a large truck, 1982–2024).
| Decade | Truck crashes / yr | Change | Fatal crashes / yr (FARS) |
|---|---|---|---|
| 1990s | 360 | — | 26.9 |

| 2010s | 652 | -13% | 29.2 |

Reported truck crashes averaged 360 a year in the 1990s and 724 a year in the 2020s. Reporting practices changed over time, so part of any change can come from reporting. NHTSA counts 42.8 fatal large-truck crashes a year in 2016–19 and 41.4 a year in 2020–24.
