Incident location, Long Island
What Happened
A 78-year-old woman is fighting for her life in critical condition after an intoxicated driver plowed into her as she crossed a street in Oceanside on Thursday afternoon, Nassau County police said. Newsday reported that at 4:41 p.m., the woman was walking in a crosswalk at the intersection of Long Beach Road and Weidner Avenue when she was struck by a 2004 Chevrolet Express Van.
Emergency responders transported the victim — whose name has not been released — to a local hospital, where she remains in critical condition, according to Nassau County police. The severity of her injuries reflects the force of the collision, which occurred in what should have been a legally protected space for pedestrians: a marked crosswalk at a signaled intersection.
Following the crash, Nassau County police conducted an investigation and determined that the driver of the van, Niall Duignan, 24, of Oceanside, was intoxicated at the time of the collision. Newsday reports that officers arrested Duignan without incident at the scene. He was charged with driving while intoxicated and second-degree vehicular assault.
Duignan is scheduled to be arraigned on Friday, June 20, 2026, at First District Court in Hempstead, according to Nassau County police and reporting by Newsday.
Location & Road Context
The crash took place at the intersection of Long Beach Road and Weidner Avenue in Oceanside, a heavily traveled south Nassau community. Long Beach Road is a major north-south commercial and residential corridor in the Oceanside area, carrying significant local vehicle and pedestrian traffic throughout the day. Intersections along this stretch regularly see foot traffic from nearby residences, businesses, and transit stops, making crosswalk safety at these junctions a persistent concern.
Oceanside has been the location of multiple serious DWI-related incidents in recent months. An Oceanside woman was indicted in a fatal wrong-way DWI crash on the Southern State Parkway earlier this spring, underscoring a troubling pattern of impaired driving incidents connected to this community.
Investigation & Legal Proceedings
Nassau County police determined through their post-crash investigation that Duignan was intoxicated at the time he struck the pedestrian. He was arrested without incident and charged with two counts: driving while intoxicated (DWI) under New York Vehicle and Traffic Law, and second-degree vehicular assault, a charge that reflects the serious physical injury suffered by the victim as a result of the alleged impaired driving.
Duignan is scheduled to appear at First District Court in Hempstead on Friday for his arraignment, at which point he will formally hear the charges against him and enter a plea. Long Island Traffic will update this report as his case proceeds through Nassau County’s criminal court system.
What This DWI Charge Means
Under New York Vehicle and Traffic Law §1192, there are several tiers of impaired driving offenses. A DWAI (Driving While Ability Impaired) charge applies when a driver’s ability is impaired by alcohol but their blood alcohol content (BAC) falls below the legal limit of 0.08% — it is a traffic infraction, not a crime, for a first offense. A standard DWI charge requires a BAC of 0.08% or higher and is a misdemeanor for a first offense, carrying penalties that can include fines of up to $1,000, a minimum six-month license revocation, a mandatory ignition interlock device, and up to one year in jail. An Aggravated DWI applies when a driver’s BAC reaches 0.18% or higher, and carries steeper fines and longer license revocation periods. Repeat offenders face felony charges, significantly higher fines, and mandatory minimum jail terms.
In this case, Duignan also faces second-degree vehicular assault under New York Penal Law §120.03, a Class E felony, which applies when a driver causes serious physical injury to another person while driving while intoxicated. This charge significantly escalates the potential consequences compared to a standalone DWI misdemeanor, including a possible prison sentence of up to four years and the collateral consequences of a felony conviction. Drivers who refuse to submit to a chemical test in New York also face automatic one-year license revocation and a civil fine of $500, regardless of whether they are ultimately convicted of any underlying DWI charge — consequences imposed independently by the DMV.
The combination of DWI and vehicular assault charges signals that prosecutors view the injuries to the 78-year-old victim as meeting the legal threshold of “serious physical injury,” a designation that carries its own legal weight and elevates the case from a misdemeanor DWI into felony territory.
Case Status & Updates
It is important to note that an arrest and criminal charge constitute an accusation — Niall Duignan is presumed innocent until proven guilty in a court of law. The charges filed by Nassau County police reflect the findings of the initial investigation and do not constitute a finding of guilt.
Duignan’s case is expected to be formally initiated at First District Court in Hempstead at his Friday arraignment, after which it will proceed through Nassau County’s criminal court system. Depending on how the case develops, it could ultimately be resolved through a plea agreement or proceed to trial.
Long Island Traffic tracks DWI cases through the courts and will update this report with arraignment outcomes, any changes to charges, plea agreements, and sentencing as they become part of the public record. Readers with information about this incident are encouraged to contact Nassau County police.
Broader Impact
This crash is a stark reminder of the vulnerability of older pedestrians at crosswalk intersections. Pedestrians aged 65 and older are disproportionately represented in pedestrian fatality and serious-injury statistics nationwide, and a collision involving a commercial van — the 2004 Chevrolet Express is a full-size cargo and passenger van — at even moderate speeds can produce catastrophic results for a person on foot, particularly in or near a crosswalk where a pedestrian has the legal right of way. The second-degree vehicular assault charge reflects exactly that reality in this case.
