What the Data Shows

Over the 2015-2023 reporting window, Delaware recorded 1,161 total road fatalities across 3 counties, with 135 deaths logged in 2023. The state's fatality rate stands at 13.1 per 100,000 residents and 1.4 per 100 million vehicle miles traveled, placing it at rank #24 of 51 US states when ordered from highest to lowest fatality rate. Against the national benchmark of 12.2 per 100K, Delaware is 7.3% above average, a gap that matters for insurers, policymakers, and drivers calibrating risk.

Cause breakdowns from NHTSA FARS show alcohol-impaired crashes accounting for 25.3% of Delaware's fatalities (294 deaths), speeding for 27.0% (314 deaths), and pedestrian incidents for 22.7% (263 deaths). The single largest contributing factor is nighttime, involved in 616 of the state's road deaths. Because these categories overlap, a nighttime fatal crash may also involve alcohol and speeding, the percentages are not additive but do reveal where enforcement and infrastructure investment can most reduce future deaths.

The trend signal is equally important: Delaware's annual fatality count is decreasing, changing -16.7% across the reporting period. Annual deaths moved from 131 in 2015 to 135 in 2023. Rural roads account for 468 deaths versus 689 on urban roads, a pattern that typically reflects longer emergency-response distances and higher travel speeds outside metro areas. Readers should treat this as descriptive data, not a ranking of driver quality, and always cross-reference the underlying FARS release for year-specific context.
