FARS data are based on police crash reports and other sources; the drunk-driving measure is based on the highest BAC of any driver in the crash. Latest data year: 2024. Figures are aggregates from NHTSA's Fatality Analysis Reporting System; no individual crash is identified.
NHTSA's FARS file lists 19 people killed in 17 fatal crashes in Alpine County, California, between 2015 and 2024, fewer than three of them in 2024.
With 1,099 residents, that is 169.4 deaths per 100,000 people a year over the ten years, about 16.8 times the California rate of 10.1 and above the national rate of 11.8. The rate rests on very few deaths and can double or halve with a single crash; through traffic on a route that passes a small population raises it further.
Counts this small move a lot from year to year, so the page shows ten-year totals and five-year bins rather than single years; 2005–2014 had 18 deaths.
Of the factors FARS records, the one that stands furthest above the state share here is motorcyclists: 47.4% against 14.1% for California.
56% of the county's fatal crashes happened between noon to 6pm, and Sunday was the most common day (35%).
Trend since 1975
Ten-year total up 6% (18 in 2005–2014, 19 in 2015–2024). The shaded band is the ten-year window used for rates and shares. County codes are matched to today's Census county list; a few historic code changes are merged.

| Crashes on rural roads | 100% | 30% | 43% |

Factors
"Alcohol" counts crashes where police reported at least one driver as drinking (FARS DR_DRINK), not the BAC-based alcohol-impaired measure NHTSA publishes separately. "Speeding" counts crashes with a driver coded as racing, exceeding the limit or too fast for conditions. Details in the methodology. Factor pages: alcohol, speeding, pedestrians, motorcycles, unrestrained occupants.
