What Happened
A Mastic man is dead after his Ducati motorcycle collided with a sport utility vehicle at a Shirley intersection Sunday evening, according to Long Island Life & Politics. The 44-year-old was pronounced dead at Stony Brook University Hospital following the crash, which occurred at approximately 7:20 p.m. at the intersection of Clyde Road and Hounslow Road.
According to Long Island Life & Politics, the motorcyclist was operating his Ducati westbound on Clyde Road when he failed to stop at a stop sign and rode directly into the intersection. His motorcycle struck the driver’s side door of a 2023 Kia SUV that was traveling southbound on Hounslow Road at the time of the collision. The impact was significant enough to prompt the impoundment of both vehicles for safety checks, a standard procedure in crashes involving fatalities.
The motorcyclist was transported from the scene to Stony Brook University Hospital, where he was later pronounced dead. He was 44 years old and resided in Mastic. The driver of the Kia SUV, a 38-year-old Shirley man, was also injured in the collision, though his injuries were described as minor. He was transported to NYU Langone Hospital-Suffolk, located in Patchogue, where he received treatment. As of the time of reporting, no charges have been publicly announced against either party.
As Long Island Life & Politics reports, the Suffolk County Police Seventh Squad has taken the lead on the investigation. Detectives from that unit are asking anyone who may have witnessed the crash or who has information relevant to the circumstances of the collision to come forward. The Seventh Squad can be reached directly at 631-852-8752. Both vehicles involved — the Ducati motorcycle and the 2023 Kia SUV — were impounded in the immediate aftermath of the crash to allow investigators to conduct thorough safety checks, a routine step in fatal collision investigations.
The crash unfolded in the early evening on a Sunday, a time of day and week when recreational motorcycle use on Long Island’s surface roads tends to peak. The specific cause cited in the available account is the motorcyclist’s failure to observe the stop sign controlling westbound traffic on Clyde Road. Whether speed, visibility conditions, mechanical failure, or other contributing factors played a role remains part of the active investigation being conducted by Seventh Squad detectives.
Location & Road Context
The collision took place at the intersection of Clyde Road and Hounslow Road in Shirley, a hamlet in the Town of Brookhaven in Suffolk County. Clyde Road runs roughly east-west through the area, while Hounslow Road runs north-south — a standard T-style or four-way intersection configuration where stop sign compliance for cross-traffic is the primary means of controlling vehicle flow. Intersections of this type on lower-volume residential and semi-residential roads in Shirley and surrounding hamlets can present elevated risk when drivers fail to yield, particularly for motorcyclists traveling at higher speeds who may have limited crash protection compared to enclosed vehicle occupants.
Shirley has been the scene of multiple serious traffic accidents in recent days. A Shirley woman was struck by a car on Dawn Drive and seriously injured on June 20, 2026, just two days before this fatal crash. A separate pedestrian was hit by a car in Shirley on the same date. The cluster of incidents underscores ongoing concerns about road safety on surface streets throughout this part of Suffolk County.
