What Happened
A 29-year-old Smithtown man was seriously injured Monday evening after his motorcycle collided with an SUV making a left turn on Middle Country Road in St. James, according to the Suffolk County Police Department. The crash occurred at approximately 7:05 p.m. on Monday, May 18, 2026, at the intersection of Middle Country Road and Southern Boulevard.
According to Patch, police identified the motorcyclist as Daniel Youngelman, 29, of Smithtown. Youngelman was operating a 2016 KTM motorcycle traveling eastbound on Middle Country Road at the time of the crash. The motorcycle collided with a 2014 Honda Pilot that was in the process of making a left turn from the westbound lanes of Middle Country Road onto Southern Boulevard. The turning maneuver placed the Honda Pilot directly in the path of the oncoming eastbound motorcycle, resulting in the collision.
As Patch reported, Youngelman was transported to Stony Brook University Hospital for treatment of serious injuries following the crash. The driver of the Honda Pilot was identified as Annette Rousselle, 66, of Centereach. Rousselle was also taken to Stony Brook University Hospital, though her injuries were described as minor, according to police. Both individuals were treated at the same facility, which serves as the region’s premier Level I trauma center.
Following standard procedure in injury crashes of this nature, both the 2016 KTM motorcycle and the 2014 Honda Pilot were impounded by authorities for safety checks, police said. Such impoundments allow investigators to examine the mechanical condition of each vehicle and determine whether any equipment failures may have contributed to the crash. At this time, no information about vehicle defects has been released by police.
The crash drew the attention of Suffolk County Police Department’s Fourth Squad detectives, who are leading the investigation. Detectives are actively seeking anyone who may have witnessed the collision or has information relevant to the case. The Fourth Squad can be reached directly at 631-854-8452, per the department’s request.
Location & Road Context
The crash took place at the intersection of Middle Country Road and Southern Boulevard in St. James, a hamlet within the Town of Smithtown in Suffolk County. Middle Country Road is a heavily traveled east-west arterial corridor that runs through the heart of Long Island’s North Shore communities, including Smithtown, St. James, and beyond. The road carries significant commuter and commercial traffic, and its intersections — including the one at Southern Boulevard — involve frequent turning movements that can create conflict points between through traffic and turning vehicles, particularly during the evening hours when visibility may be reduced.
This stretch of Middle Country Road has at least one other recorded incident in our database, underscoring the ongoing safety challenges at intersections along this busy corridor. Left-turn collisions involving motorcycles are among the most common and serious crash types on Long Island’s arterial roads, as motorcycles traveling at speed in through lanes can be difficult for turning drivers to judge accurately.
Investigation & Legal Proceedings
The investigation into the Monday evening crash remains active and is being conducted by Fourth Squad detectives from the Suffolk County Police Department, according to Patch. No charges have been announced at this time, and police have not publicly released a determination of fault. The impoundment of both vehicles for safety checks suggests that investigators are taking a thorough approach to establishing the exact circumstances of the collision before drawing any conclusions.
Anyone who witnessed the crash or has information that could assist detectives is urged to contact the Fourth Squad at 631-854-8452. Tips can also typically be submitted anonymously. As the investigation progresses, additional details — including whether any traffic violations or charges will be filed — may be released by the Suffolk County Police Department.
Broader Impact
Left-turn crashes involving motorcycles represent a disproportionate share of serious motorcycle injuries and fatalities across New York State. In this type of collision — where an oncoming motorcyclist is struck by a vehicle executing a left turn across their lane — the motorcyclist typically bears the full force of impact with little protection. Youngelman’s serious injuries and transport to Stony Brook University Hospital, the region’s only Level I trauma center, reflect the life-threatening nature these collisions can carry, and serve as a stark reminder of the vulnerability of motorcyclists at busy intersections like the one at Middle Country Road and Southern Boulevard in St. James.
