Correction — September 18, 2026: The previous headline claimed this road led Long Island in fatal crashes without a valid comparative dataset. We withdraw that ranking and replace it with the federal record. The original URL and publication record are retained.
| Corridor, Nassau and Suffolk portions | Fatal crashes | People killed |
|---|---|---|
| Southern State Parkway | 140 | 169 |
The historical record establishes a serious public safety burden. It does not establish a cause for each crash, the performance of a specific ramp, or the risk of a journey today. Those questions need case-level investigation and appropriate road and traffic data.
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.
