Where the I-10 numbers come from

Counted from NHTSA's Fatality Analysis Reporting System, 2024 Annual Report File: every fatal crash whose road NHTSA filed as I-10 in California (filed under 27 spellings, such as "I 10 HOT LANE", "I-10", "I-10 SAN BERNARDINO FREEWAY", "I-10 SAN BERNARDINO FWY"). 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.
