Correction — September 18, 2026: The earlier danger ranking relied on monitoring coverage and severity labels that do not measure injury outcomes or exposure. The ranking has been withdrawn. The original URL and publication record are retained.
The replacement federal fatal-crash report covers 17 mapped corridors and publishes its data and limitations. Counts describe a burden of deaths; they are not a validated danger score.
| County | Fatal crashes | People killed |
|---|---|---|
| Nassau | 1148 | 1222 |
| Suffolk | 1951 | 2080 |
County totals cover all qualifying roads in each county. They must not be presented as the sum of only the 17 featured corridors.
How to read these records
The figures cover 2010–2024, not 2026. The downloaded 2024 files were labeled preliminary when retrieved on September 17, 2026. A fatal crash and a person killed are different units: a single crash can kill more than one person.
NHTSA’s Fatality Analysis Reporting System records qualifying fatal traffic crashes. It does not provide a census of every injury, breakdown or lane closure. Our tables count distinct year-and-case identifiers and retain the reported fatalities.
The full road report and downloadable data explain county limits, road assignment and missing coordinates. These are historical counts, without a denominator for miles driven, trips or traffic volume. They cannot establish the safest route or the chance of a crash on a particular trip.
For present conditions, check 511NY and posted restrictions. Historical counts do not establish whether a road is open now.
