Road names as recorded by police and normalised to common Long Island names.
When and where
- Of the 15 crashes with a recorded time, 8 happened between 8 p.m. and 6 a.m., 3 between 4 and 8 p.m., 3 between 10 a.m. and 4 p.m., and 1 between 6 and 10 a.m.
- 60% happened in darkness.
- 0 of the 16 deaths were on expressways or parkways; 16 were on arterials and local streets.
- 1 crash killed more than one person.
- In at least 1 crash, 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 11 fatal crashes in Mastic since then:
- Town roads 8 (73%)
- State highways 2 (18%)
- City or village streets 1 (9%)
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: 6.9 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 Brookhaven, 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 Mastic is for the Town of Brookhaven, which contains it. Police reported 44,155 crashes there from 2021 through 2024 — about 30.2 a day. 11,428 (25.9%) injured someone and 172 were fatal. [D]

Counts are crashes, not people. The municipality is entered by the reporting police agency, and coding is less consistent for small villages, so compare places with care.

Notable facts about Mastic
- The National Park Service's own directions to the William Floyd Estate route visitors off the William Floyd Parkway from either Long Island Expressway Exit 68 or Sunrise Highway Exit 58S.[3]
- The Old Mastic House, ancestral home of Declaration of Independence signer William Floyd, was built by Nicoll Floyd after the family had acquired 4,400 acres by 1718.[2]
- The National Park Service's own address for the William Floyd Estate — 245 Park Drive — places the historic 'Old Mastic House' in present-day Mastic Beach, not Mastic.[3]
History
The hamlet takes its historic identity in large part from the Floyd family estate, whose main house is still called the Old Mastic House. The National Park Service, which now administers the property as part of Fire Island National Seashore, states that "[a]n active supporter of the American Revolution, William Floyd was one of four New Yorkers to sign the Declaration of Independence," and that the Floyd family "grew their enterprise as affluent merchants and landowners in the town of Brookhaven, New York, as early as the 17th century."[2] By 1718 the family had acquired 4,400 acres "on which Nicoll Floyd built the family's ancestral home, the Old Mastic House, and ran a prosperous Northern plantation which was passed down to William Floyd and later generations."[2] The property was eventually donated to the National Park Service; the Park Service's own visitor directions place the estate's entrance at 245 Park Drive, in present-day Mastic Beach, NY 11951, reflecting how the hamlet boundaries in this area have shifted since the Floyd era.[3]
How the roads got here
William Floyd Parkway, County Road 46, is the hamlet's principal north–south route; a New York State memorial-bridge listing documents the road crossing NY 27 (Sunrise Highway) at a bridge in the neighboring hamlet of Brookhaven, and the National Park Service directs visitors to the William Floyd Estate via "Exit 68 from the Long Island Expressway (I-495) or Exit 58S from Sunrise Highway (NY-27E) onto the William Floyd Parkway (Route 46)."[5][3]
The state's own touring-route description of NY 27A (Montauk Highway) ends that designation at the "Oakdale Exit (NY 27)" in the Town of Islip, well west of Mastic; this fact book therefore cannot confirm Montauk Highway through Mastic as a state route from this source, and its current ownership was not otherwise verified.[6]
Government, courts and policing
Mastic has no government of its own; it is an unincorporated hamlet of the Town of Brookhaven. The Suffolk County Police Department's Seventh Precinct, whose own page describes its territory as "the eastern most sections of the Town of Brookhaven to the Riverhead and Southampton Town lines," is the department's precinct for this part of Brookhaven, although its page does not name Mastic specifically.[1]
Civil claims against the Town of Brookhaven over a defective or dangerous street, highway, bridge, culvert or crosswalk are governed by Town of Brookhaven Code Chapter 84, "Notice of Defective or Dangerous Conditions," adopted June 16, 1987 (Local Law No. 7-1987) and most recently amended March 10, 2016. Section 84-1 provides that "[n]o civil action shall be commenced against the Town of Brookhaven or the Superintendent of Highways for damages or injuries to persons or property sustained by reason of the defective, out-of-repair, unsafe, dangerous or obstructed condition of any highway, street, bridge, culvert, or crosswalk or pedestrian walkway open to the public" unless written notice was first given to the Town Clerk or Superintendent of Highways.[4]
Higher-level civil and criminal matters from Brookhaven hamlets are handled within the Suffolk County court system, whose 10th Judicial District administrative offices are at 400 Carleton Avenue, Central Islip.[7]

Frequently Asked Questions
What should I do after a car accident in Mastic, NY?
Move to safety and call 911 immediately, then document the scene with photos and exchange insurance and contact information with everyone involved. File a police report with SCPD and notify your insurer promptly. 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.
Which roads are most dangerous in Mastic?
Montauk Highway and William Floyd Parkway carry the heaviest traffic through Mastic and account for most of the reported crashes we track. The William Floyd Parkway corridor, a high-speed north-south arterial with signalized cross streets. Commercial driveways, signalized intersections, and turning movements along these corridors drive the local crash mix.
