Road pages for New Hampshire

Every numbered road in New Hampshire with 15 or more fatal crashes from 2022 to 2024, each with its crashes by year, county, hour and weekday.

Where the New Hampshire numbers come from

Every figure on this page is counted from NHTSA's Fatality Analysis Reporting System, the federal census of fatal crashes on US public roads, 2024 Annual Report File. A fatal crash is one in which someone died within 30 days. Road names are normalised ("I35 FRONTAGE" and "I-35" are the same road; frontage roads and ramps are left out of road counts). Fields NHTSA coded as unknown show as "Not reported"; a share is only given over 20 crashes, otherwise "Not enough data". The full method.
