Where the State Highway 138 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 138 in California (filed under 13 spellings, such as "SR- 138", "SR- 138 PALMDALE BLVD", "SR-138", "SR-138 47TH ST"). 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.
