Crash severity

5.5

Share of reported crashes that were fatal: 5.5 per 1,000, 2021-2025

n=44 · window 2021-2025

well above possibly well above the state rate

95% range: 4.0–7.4
2.3%

Suspected-serious share of the source-defined reported-crash injury universe, 2021-2025

n=187 · window 2021-2025

near broadly near the state share

95% range: 2.0%–2.7%

Keep in view: The share of reported crashes that were fatal does not measure a county's danger, a traveler's risk, or the cause of any crash.

Fatal-crash timing

35.1%

Share of FARS fatal crashes that were night, 2021-2024

n=13 · window 2021-2024

below somewhat below the state share

95% range: 21.8%–51.2%
29.7%

Share of FARS fatal crashes that were weekend, 2021-2024

n=11 · window 2021-2024

near broadly near the state share

95% range: 17.5%–45.8%
27.0%

Share of FARS fatal crashes that were impaired involved, 2021-2024

n=10 · window 2021-2024

below somewhat below the state share

95% range: 15.4%–43.0%

Keep in view: These time and involvement shares describe fatal crashes in FARS and do not measure an individual's risk or establish why a crash occurred.

Population context

259.8

Annual reported crashes per 10,000 residents (2024 ACS population), 2025

n=1689 · window 2025

above above the state rate

245.4

Five-year annualized reported crashes per 10,000 residents (2024 ACS population), 2021-2025

n=7978 · window 2021-2025

above somewhat above the state rate

95% range: 240.0–250.8

Keep in view: Crashes per resident use population as context, not miles traveled, and do not measure an individual resident's driving risk.

Truck-crash context

0.92

Truck-crash share relative to overall reported-crash share, 2021-2023

n=94 · window 2021-2023

near broadly near the state level

95% range: 0.75–1.13

Keep in view: This location quotient compares shares of reported crashes and does not measure truck-driver fault, carrier safety, or roadway danger.
