Road names as recorded by police and normalised to common Long Island names.
When and where
- Of the 16 crashes with a recorded time, 5 happened between 8 p.m. and 6 a.m., 7 between 4 and 8 p.m., 2 between 10 a.m. and 4 p.m., and 2 between 6 and 10 a.m.
- 44% happened in darkness.
- 0 of the 16 deaths were on expressways or parkways; 16 were on arterials and local streets.
- In at least 2 crashes, a driver had a reported blood-alcohol concentration of .08 or higher. This counts known test results only; NHTSA's official alcohol estimates, which impute untested drivers, are higher.
Who owns the roads where they happened (2015–2024)
FARS has recorded the owner of the roadway since 2015. Of the 14 fatal crashes in Hampton Bays since then:
- Town roads 7 (50%)
- State highways 5 (36%)
- County roads 2 (14%)
Ownership matters in New York because claims against a county, town, city or village generally require a notice of claim within 90 days (General Municipal Law § 50-e), while claims against the State are brought in the Court of Claims under Court of Claims Act § 10. This is general information, not legal advice.
Rate: 7 traffic deaths per 100,000 residents per year, against 9.1 for Suffolk County. This is a resident-based rate, not a measure of how risky the roads are to drive: crashes are counted where they happen, not where the people involved live, so a small community crossed by a major highway shows a high rate.

All reported crashes in the Town of Southampton, 2021–2024
New York's crash file codes each crash to a town, city or village — never to a hamlet — so the finest official count that covers Hampton Bays is for the Town of Southampton, which contains it. Police reported 9,585 crashes there from 2021 through 2024 — about 6.6 a day. 2,049 (21.4%) injured someone and 31 were fatal. [D]

Move to safety and call 911 immediately, then document the scene with photos and exchange insurance and contact information with everyone involved.

New York is a no-fault state, so your own PIP coverage pays initial medical costs regardless of fault, and you have just 30 days to file the NF-2 application.

The Sunrise Highway Exit 64–65 area, where East-End-bound traffic transitions toward the Hamptons.
