The road is a scale of fatal crashes per 100,000 residents in 2024, 0 to 40. The yellow post is Tennessee; the white posts are the United States.

Per 100,000
1,093 fatal crashes ÷ 7,251,291 residents × 100,000 = 15.1
Five-year
5,874 crashes (2020 to 2024) ÷ 35,362,068 resident-years × 100,000 = 16.6
Per 100M miles
1,093 fatal crashes ÷ 78,904 million vehicle-miles (2024) × 100 = 1.4
Same year
United States: 36,297 ÷ 340,003,797 = 10.7

Road type is FARS FUNC_SYS; speeding is any vehicle coded SPEEDREL 2 to 5; drinking is any driver coded DRINKING = 1 (police-reported, not a blood-alcohol test). Road names are the trafficway strings as the police coded them, counted as written, so the same road can appear under two spellings.

Counties in Tennessee

Alphabetical, with each county’s 2024 fatal crashes and rate per 100,000. The site does not rank them: a small county’s rate swings on one crash.

How this is counted

  • Fatal crashes are rows in NHTSA’s Fatality Analysis Reporting System (FARS) file FARS2024NationalCSV.zip, accident.csv, one row per crash on a public road in which someone died within 30 days. Deaths are the FATALS field. Counties are the FARS STATE and COUNTY codes joined to Census FIPS codes.
  • Population is the Census Bureau’s July 1 estimate for the same year, county totals, Vintage 2025. Rate per 100,000 = crashes ÷ population × 100,000.
  • Vehicle-miles are FHWA Highway Statistics table VM-2, total annual travel by state. Rate per 100 million vehicle-miles = crashes ÷ miles × 100,000,000, the form the federal safety rule uses (23 CFR 490.207). FHWA publishes no county vehicle-miles, so county pages have no per-mile rate.
  • The five-year average is total crashes over the years with both inputs ÷ total population over those years × 100,000, the rolling form in 23 CFR 490.207.
  • What it cannot say. FARS has no injury-only or property-damage crashes, no congestion, and nothing about any one driver, trip or road’s risk. A crash is counted where it happened, not where the people lived. Rates are not ranked here; comparing two places means comparing both sets of inputs.
