What Happened

A pedestrian was airlifted to a hospital with serious injuries following a crash on the A140 at Stuston, near Diss, Tuesday morning, according to Suffolk Police. Emergency services were called to the scene shortly before 8:00 a.m. on March 31, 2026, after reports of the collision involving the pedestrian.

The pedestrian sustained serious injuries in the crash and required immediate medical attention, a Suffolk Police spokesperson confirmed. Due to the severity of the injuries, emergency medical personnel made the decision to airlift the victim to Addenbrooke’s Hospital in Cambridge for specialized treatment. The decision to use air transport typically indicates the critical nature of the injuries sustained and the need for rapid access to trauma care facilities.

The collision prompted an immediate emergency response from multiple agencies, with first responders arriving at the Stuston location on the A140 shortly after the 8:00 a.m. call. The crash site is located near the market town of Diss, in an area that sees regular commuter and commercial traffic during morning hours. Details about the specific circumstances that led to the pedestrian being in the roadway at the time of the collision have not been released by authorities.

Suffolk Police confirmed that the incident involved a vehicle striking the pedestrian, though specific details about the type of vehicle involved, the direction of travel, or the identity of the driver have not been made available. The spokesperson indicated that the pedestrian’s condition remains serious following their transport to Addenbrooke’s Hospital, which serves as a major trauma center for the region.

The crash has resulted in significant traffic disruptions throughout the area, with authorities implementing comprehensive road closures to facilitate the emergency response and subsequent investigation. The A140 remains completely blocked at Stuston, creating major delays for commuters and commercial traffic attempting to navigate through the corridor during peak morning hours.

Road closures have been established along the A140/A143 roundabout, a key intersection that typically handles substantial traffic volumes throughout the day. Additionally, the junction with the B1077 has been closed to vehicular traffic as part of the emergency response protocol. These closures have effectively isolated the crash scene while allowing emergency personnel to work safely and conduct their preliminary investigation.

Suffolk Police have advised motorists to avoid the entire area, emphasizing that the route will remain closed for an extended period. The duration of the closure appears to be tied to both the ongoing investigation into the circumstances of the crash and the complexity of the scene processing that follows serious injury collisions involving pedestrians.

Location & Road Context

The A140 at Stuston represents a significant transportation corridor in Suffolk County, connecting communities near the Norfolk border and serving as a vital link for both local and regional traffic. The roadway carries substantial volumes of commuter traffic during morning and evening hours, with the Stuston area being particularly busy due to its proximity to Diss and the surrounding rural communities that depend on the route for access to employment centers and services.

The section of the A140 where the crash occurred is characterized by its role as a primary north-south route through this part of Suffolk, with the nearby A143 roundabout serving as a major junction point for traffic traveling between different regions. The B1077 junction adds another layer of complexity to traffic patterns in the area, as it provides connectivity to smaller communities and rural areas that rely on the A140 as their primary access to the broader road network.

Suffolk Police have not released information regarding potential charges or the status of any driver involved in the collision. The investigation into the circumstances surrounding the pedestrian crash remains active, with authorities likely focusing on factors such as visibility conditions, speed, and the specific location where the pedestrian was struck. The extended road closure suggests that investigators are conducting a thorough examination of the crash scene, including measurements, photographic documentation, and evidence collection that will be crucial to understanding how the incident occurred.

The serious nature of the pedestrian’s injuries indicates that the investigation will likely be comprehensive, with police examining all aspects of the collision to determine contributing factors and potential liability. Such investigations typically involve accident reconstruction specialists and detailed analysis of vehicle damage, road conditions, and witness statements when available.

Frequently Asked Questions

What should I do if I'm in a car accident in Suffolk County?

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.
