Incident location, Long Island
What Happened
A four-year-old child was rushed to a local hospital in critical condition after a single-car crash on the Southern State Parkway westbound near Exit 20 in the early afternoon of Tuesday, June 17, 2026, according to a report by Long Island Life & Politics.
At approximately 2:00 p.m., New York State Police troopers responded to the westbound lanes of the Southern State Parkway near Exit 20, the Grand Avenue exit. Upon arrival, troopers observed a 2006 Nissan Sentra that had veered off the roadway and struck trees. Both the vehicle’s operator and the young child were found entrapped inside the car, requiring emergency personnel to extract them from the wreck, per the Long Island Life & Politics report.
Once both occupants were removed from the vehicle, the four-year-old child was transported to a local hospital in critical condition. The report does not specify which hospital received the child, nor does it detail the nature or extent of the injuries sustained. The driver’s condition following the crash was also not disclosed in the initial reporting.
As emergency responders worked the scene, westbound lanes on the Southern State Parkway were closed from approximately 2:00 p.m. through 6:00 p.m. — a four-hour shutdown that affected afternoon traffic along one of Long Island’s busiest parkway corridors. No additional vehicles were involved in the incident; this was a single-car crash in which the Nissan Sentra left the traveled portion of the roadway and came to rest against trees lining the parkway. The cause of the crash had not been publicly established at the time of initial reporting, and the investigation was described as ongoing by state police.
The New York State Police are actively seeking information from anyone who may have witnessed the collision or the moments leading up to it. Witnesses are urged to contact NYSP at (631) 756-3300 with any relevant details. No arrests or charges had been announced as of the time of reporting.
Location & Road Context
The crash took place on the Southern State Parkway westbound near Exit 20, which connects to Grand Avenue in the vicinity of Hempstead. The Southern State Parkway is a heavily traveled east-west artery running across Nassau and into Suffolk County, connecting communities across the south shore of Long Island and serving as a primary commuter and recreational route for millions of residents.
The stretch near Exit 20 is no stranger to serious incidents. Our database at Long Island Traffic shows 633 recorded incidents on the Southern State Parkway, and the days immediately surrounding this crash generated a cluster of related reports — including multiple entries from June 17 and June 18, 2026, referencing what appear to be the same collision: a moderate incident closing westbound lanes near Hempstead, an accident investigation that closed lanes the same afternoon, and a follow-up report on the critically injured child dated June 18. The density of incidents in that 24-hour window underscores the ongoing danger posed by this corridor, particularly in the Nassau County midsection near the Grand Avenue interchange.
Investigation & Legal Proceedings
As of the time of the initial report published by Long Island Life & Politics, the investigation into this crash remains ongoing. No cause for the departure from the roadway has been officially announced, and no charges or arrests have been reported in connection with the incident. New York State Police are handling the investigation and have made a public appeal for witnesses to come forward. Anyone with information about the crash — including those who may have observed the Nissan Sentra in the moments before impact — is asked to call the New York State Police at (631) 756-3300.
Broader Impact
Single-car crashes involving the departure of a vehicle from the roadway and collision with fixed objects — such as the trees struck in this incident — represent one of the deadliest categories of accidents on Long Island. When a young child is transported in a vehicle that leaves the road at highway speed, the outcomes can be catastrophic even when child safety seats are properly used. The critical condition of this four-year-old highlights why New York State law mandates that children under four years of age be secured in a federally approved child restraint system, and that children between four and eight years old who are under 100 pounds be buckled into a booster seat — requirements enforced under New York Vehicle and Traffic Law § 1229-c. Whether the child in this crash was properly restrained has not been disclosed by investigators.
