Where the State Highway 178 numbers come from

Counted from NHTSA's Fatality Analysis Reporting System, 2024 Annual Report File: every fatal crash whose road NHTSA filed as State Highway 178 in California (filed under 6 spellings, such as "SR-178", "SR-178 24TH ST", "SR-178 E RIDGECREST BLVD", "SR-178 GOLDEN STATE"). Ramps, frontage and service roads are left out. Where two routes share a road, NHTSA files each crash under one of them, so a shared stretch counts on one route only. A fatal crash is one in which someone died within 30 days. Totals in state and news reports for a road usually differ: they include ramps and frontage roads, or count from preliminary reports.
