The Clock Behind the Crash: America's Most Dangerous Hours on the Road
Data reflects 38,988 of the 39,254 total traffic fatalities recorded in NHTSA's Fatality Analysis Reporting System in 2024. The remaining 266 fatalities could not be assigned to a specific hour due to unknown or unrecorded crash times and are excluded from this table. Fatality counts represent persons killed in fatal crashes occurring within each one-hour window regardless of crash type, road type, or contributing behavior. Percentages reflect each hour's share of the 38,988 fatalities where crash time was known.
