What Happened

Marco F. Pineda, 36, of Easthampton was arrested Friday night after driving while intoxicated and fleeing the scene of a two-vehicle collision in Water Mill, according to police. Officers responded to reports of the crash around 8 p.m. at the intersection of Montauk Highway and Proprietors Road, where they discovered one of the vehicles involved had already fled the scene eastbound.

No injuries were reported in the initial collision, police say. However, the incident quickly escalated into a multi-jurisdictional pursuit when the fleeing driver continued operating his vehicle while impaired. The crash occurred at one of Water Mill’s busiest intersections, where Proprietors Road meets the heavily traveled Montauk Highway corridor.

A patrol officer in neighboring Sagaponack observed a vehicle failing to maintain its lane shortly after the initial crash report, according to authorities. The officer initiated a traffic stop on the erratic driver, leading to Pineda’s arrest. During the stop, the officer determined that Pineda was intoxicated and connected him to the earlier hit-and-run collision in Water Mill.

Police took Pineda to headquarters following his arrest, where he was held overnight for morning arraignment at Southampton Town Justice Court. The charges against him include driving while intoxicated, leaving the scene of an accident with property damage, and several additional traffic violations, authorities report. The specific nature of the additional traffic violations was not immediately disclosed by police.

The incident began when two vehicles collided at the intersection of Montauk Highway and Proprietors Road around 8 p.m. Friday. While one driver remained at the scene as required by law, Pineda allegedly fled eastbound on Montauk Highway, according to the police investigation. The collision caused property damage to both vehicles, though the extent of the damage was not specified in the initial police report.

The quick apprehension came as a result of coordinated police work between Water Mill and Sagaponack departments. The Sagaponack patrol officer’s observation of the lane departure violations proved crucial in identifying and stopping the suspect vehicle. This type of inter-departmental cooperation is common in the East End, where municipal boundaries are close and officers frequently assist neighboring jurisdictions.

Location & Road Context

The crash occurred at the intersection of Montauk Highway and Proprietors Road in Water Mill, a critical junction in the hamlet’s transportation network. Montauk Highway serves as the primary east-west arterial road through the Hamptons, carrying significant traffic volumes especially during weekend periods when seasonal residents and visitors travel to and from the area.

Proprietors Road intersects Montauk Highway in the heart of Water Mill’s commercial district, near several restaurants, shops, and residential developments. The intersection experiences heavy traffic during peak hours and weekend periods, making it a location where drivers must exercise particular caution. The eastbound direction that Pineda allegedly fled leads toward Bridgehampton and eventually Montauk Point, passing through several other Hampton communities where police maintain regular patrols.

Pineda faces multiple charges stemming from the Friday night incident, with the most serious being the DWI charge. In New York State, a first-offense DWI carries potential penalties including license suspension, fines, and possible jail time. The leaving the scene charge adds additional legal complications, as New York law requires drivers to remain at accident scenes and exchange information, regardless of fault determination.

The case proceeded to Southampton Town Justice Court for morning arraignment following Pineda’s overnight detention at police headquarters. The arraignment would typically involve formal reading of charges, entry of a plea, and determination of bail or release conditions. The additional traffic violations mentioned by police likely relate to the lane departure behaviors observed by the Sagaponack officer, though specific details of these charges were not immediately available from court records.

Broader Impact

This incident highlights the effectiveness of coordinated police patrols across East End communities, where the close proximity of municipal boundaries allows for rapid cross-jurisdictional responses. The quick apprehension of Pineda demonstrates how erratic driving behaviors often lead to the detection of more serious offenses, as the initial traffic stop for lane violations revealed both the intoxication and connection to the hit-and-run crash. The Friday night timing of the incident also reflects patterns commonly seen in DWI enforcement, when social activities and alcohol consumption typically increase throughout the Hamptons region.

Frequently Asked Questions

What should I do if I'm in a car accident Montauk Highway in Water Mill?

Call 911 immediately if anyone is injured or if the vehicles can't be moved safely off the roadway. Stay at the scene — leaving the scene of an accident with injuries is a crime under New York Vehicle and Traffic Law §600. Exchange license, registration, and insurance information with every other driver involved. Take photographs of every vehicle, the position of the vehicles before they're moved, all license plates, the road surface, traffic signs, and any visible injuries. Get the names and phone numbers of every witness — police often won't capture bystander witnesses on their own. Seek medical attention within 24 hours even if you feel fine; soft-tissue injuries and concussions can take a day or two to present, and a delayed medical visit weakens an injury claim. SCPD covers the five western towns of Suffolk County. The five East End towns (Southampton, East Hampton, Riverhead, Southold, Shelter Island) have their own town/village police forces. New York State Police Troop L responds to accidents on state highways including I-495 (LIE), Sunrise Highway (NY-27), Sagtikos Parkway, and Heckscher State Parkway.

How long do I have to file a no-fault claim in New York?

Thirty days. New York Insurance Law §5102 requires you to file a Personal Injury Protection (PIP/no-fault) application with the insurer of the vehicle you were in (or, if you were a pedestrian or cyclist, with the insurer of the striking vehicle) within 30 days of the accident. Missing the 30-day deadline can void your no-fault benefits — that's up to $50,000 in medical bills and 80% of lost wages (capped at $2,000/month) per injured person. The form is the NF-2 application; your insurance carrier provides it on request. New York no-fault is a true PIP system: it pays regardless of who caused the crash.

How long do I have to sue after a Long Island car accident?

Three years from the date of the accident for personal injury claims under CPLR §214(5). Wrongful death claims have a two-year deadline under EPTL §5-4.1. If a government entity is involved (a county vehicle, a road defect on a state highway, a defective traffic signal, a county bus), you must file a Notice of Claim within 90 days under General Municipal Law §50-e — that's a non-negotiable jurisdictional deadline, and missing it usually bars the claim entirely. Property-damage-only claims have the same three-year clock. The clock starts on the day of the accident, not the day you discover the full extent of an injury.

How do I get a copy of the police accident report?

If Suffolk County Police Department (SCPD) responded to the scene, the report is filed under an MV-104A form. In New York State, you can request a copy through the DMV at https://dmv.ny.gov/vehicle-safety/get-copy-accident-report (roughly $7 online, $10 by mail) once the responding agency has uploaded it to the state system, which usually takes 5-10 business days. NCPD and SCPD also have their own direct-request processes through the precinct that responded. If you weren't injured but the property damage exceeded $1,000, New York VTL §605 requires you (the driver) to file your own MV-104 report with the DMV within 10 days regardless of whether police responded.
