A car accident on Long Island can send your life in two directions at once, toward recovery and toward a legal process most people are completely unprepared for.
Whether your crash happened on the Long Island Expressway in Suffolk County or on Hempstead Turnpike in Nassau County, the court system, the insurance rules, and the documentation requirements are different from New York City, and the county where your accident occurred determines where your case will be filed.
Nassau County cases are handled at Nassau County Supreme Court in Mineola. Suffolk County cases are handled at Suffolk County Supreme Court in Riverhead.
Getting that distinction right from the start, and making sure the police report from Nassau County PD or Suffolk County PD accurately reflects what happened, can shape the entire outcome of your claim.

Long Island Car Accident Laws and Court Process
Car accident cases on Long Island are governed by New York State law, but where your case is filed depends entirely on which county the crash occurred in.
Nassau County cases are filed in Nassau County Supreme Court, located at 100 Supreme Court Drive in Mineola. Suffolk County cases are filed in Suffolk County Supreme Court, located at 1 Court Street in Riverhead.
These are separate civil court systems with their own dockets, timelines, and procedural rules, and filing in the wrong venue can create delays that hurt your case.
New York is a pure comparative negligence state, which means your compensation can be reduced based on your share of fault in the accident.
Insurance companies on Long Island are experienced at using this rule to lower payouts, which is why the accident report generated by Nassau County PD or Suffolk County PD matters as much as it does. If the report contains inaccurate information about how the crash happened or who was involved, correcting that record early is critical.
Long Island personal injury cases also move through a discovery process that includes exchanging medical records, accident reconstruction evidence, and witness statements before any trial or settlement conference.
The timeline from filing to resolution can vary significantly depending on the county, the court’s docket, and the complexity of the injuries involved. Having an attorney who understands how Nassau and Suffolk County courts operate gives your case a structural advantage from the first day a claim is filed.
Dangerous Roads on Long Island
Long Island’s road network carries some of the heaviest traffic volume in New York State, and certain corridors account for a disproportionate share of serious collisions every year. Understanding where crashes happen most frequently matters not just for safety but for building a credible claim, because road conditions, signal timing, and highway design can all become relevant factors in establishing liability.
Nassau County
| Road | Primary Risk |
| Hempstead Turnpike | Intersection conflicts, heavy commercial traffic |
| Sunrise Highway | Grade-level crossings, busy commercial corridors |
| Merrick Road | Rear-end and left-turn accidents |
| Old Country Road | High-volume surface road, frequent stop-and-go conflicts |
| Northern State Parkway | Speed-related crashes during peak commuting hours |
Suffolk County
| Road | Primary Risk |
| Long Island Expressway (I-495) | Multi-vehicle and fatal collisions, Exits 40 to 60 |
| Sunrise Highway (continuing east) | Same risks as Nassau, high commercial volume |
| Jericho Turnpike | Rear-end and sideswipe crashes, heavy turning traffic |
| Montauk Highway | Seasonal traffic spikes, elevated accident rates |
| Nicolls Road | High-speed rural intersection collisions, limited lighting |
No-Fault and the Serious Injury Threshold
New York is a no-fault insurance state, which means that after a car accident on Long Island, your own insurance policy is the first place you turn for coverage of medical expenses and lost wages, regardless of who caused the crash.
To access those benefits, you must file a no-fault application with your insurance carrier within 30 days of the accident. Missing that window can result in a denial of benefits that is very difficult to reverse, even if your injuries are serious and well-documented.
No-fault coverage has limits, and it does not compensate you for pain and suffering. To pursue those damages in a lawsuit against the at-fault driver, your injuries must meet New York’s serious injury threshold under Insurance Law Section 5102(d).
Qualifying injuries include significant disfigurement, bone fracture, permanent limitation of a body organ or member, significant limitation of use of a body function or system, and injuries that prevent you from performing substantially all of your daily activities for at least 90 of the 180 days following the accident.
Insurance companies routinely challenge whether injuries meet this threshold, which is one of the primary reasons having an attorney involved early in the process matters.
If your Long Island accident involved a municipal vehicle, an MTA Long Island Bus, or a vehicle operated by a government agency, an additional deadline applies.
A Notice of Claim must typically be filed within 90 days of the accident before a lawsuit against a public entity can proceed.
Missing this deadline can permanently bar your claim against that defendant. If a LIRR crossing or railroad-related vehicle was involved in your crash, the claims process involves federal and state rules that require immediate attention.
Recent Car Accidents on Long Island
Long Island roads see serious crashes every week across both Nassau and Suffolk County. Here are some of the most significant recent accidents that highlight why having an attorney ready matters:
- Southern State Parkway, Hempstead — March 15, 2026: A six-car crash near Exit 17S killed two elderly people and injured several others. A 36-year-old Oceanside woman was arrested for DWI and faces homicide charges after allegedly losing control of her vehicle, crossing the median, and striking multiple cars traveling in the opposite direction. Two people in their 80s were pronounced dead at the scene.
- Northern State Parkway — April 27, 2026: Two people were seriously injured in a major two-vehicle collision on the Northern State Parkway. New York State Police launched an investigation into the circumstances of the crash on one of Long Island’s most heavily traveled corridors.
- Southern State Parkway — May 3, 2026: A three-vehicle crash caused significant property damage on the Southern State Parkway, part of an unusually active day for accidents on that corridor with multiple incidents reported within hours of each other.
- Port Washington to Americana Manhasset — May 13, 2026: A minor caused multiple vehicle crashes during a police pursuit from Port Washington to the Americana Manhasset mall in Nassau County. The juvenile was charged with attempted murder, grand larceny, reckless endangerment, and resisting arrest.
- Route 112, Coram — January 4, 2026: A woman was killed after a Jeep Wrangler ran into her vehicle on Route 112 in Suffolk County, sending her car into two additional vehicles. The driver of the Jeep was hospitalized in stable condition.
These accidents reflect a pattern that plays out on Long Island roads every week. Some involve drunk drivers. Some involve high-speed pursuits.
Some happen at intersections that have seen crashes before. What they share is that the victims and their families were left to navigate insurance companies, police reports, and legal deadlines at the worst possible moment.
If you or someone you know was injured in a Long Island car accident, do not wait to get legal advice. The sooner an attorney is involved, the better protected your claim will be.
What to Do After a Car Accident on Long Island
The steps you take in the first hours after a crash on Long Island have a direct impact on the strength of your claim. Here is what to do:
- Call 911 immediately. Even if the accident seems minor, a police response creates an official record of the crash. Do not leave the scene without a report being filed.
- Get the police report number. Before you leave the scene, ask the responding officer for the report number. Nassau County PD and Suffolk County PD each have their own reporting systems, and knowing which department responded helps your attorney obtain the full report quickly.
- Note the responding precinct or station. If possible, identify the precinct or police station handling the report. This matters because follow-up requests for accident documentation go directly to the reporting agency, and delays in obtaining that record can slow your claim.
- Seek medical care immediately. Even if you feel fine at the scene, get evaluated by a medical professional as soon as possible. Gaps in medical treatment are one of the first things insurance companies use to minimize or deny a claim.
- Preserve all evidence. Photograph the vehicles, the road, the intersection, any visible injuries, and any contributing factors such as obscured signs or road damage. Collect names and contact information from any witnesses before they leave the scene.
- Do not speak to any insurance company without an attorney. Insurance adjusters, including your own, are trained to limit payouts. Do not give a recorded statement, accept any settlement offer, or sign any documents before speaking with a lawyer.
- Call Michael J. Redenburg. The sooner an attorney is involved, the better protected your claim is from procedural mistakes, missed deadlines, and insurance company tactics designed to reduce what you recover.
Frequently Asked Questions
What court handles car accident cases on Long Island?
It depends on where your accident occurred. If your crash happened in Nassau County, your case will be filed in Nassau County Supreme Court at 100 Supreme Court Drive in Mineola. If it happened in Suffolk County, your case goes to Suffolk County Supreme Court at 1 Court Street in Riverhead. The county where the accident took place determines venue, and filing in the correct court from the start matters for your timeline and case management.
Does it matter whether my crash happened in Nassau or Suffolk County?
Yes, it matters significantly. Nassau and Suffolk County have separate court systems, separate police departments, and separate procedural timelines. The county also affects which judges and court rules apply to your case, how quickly discovery moves, and how settlement conferences are scheduled. An attorney familiar with both courts can navigate those differences on your behalf.
What if I was hit by a LIRR vehicle or injured at a railroad crossing on Long Island?
LIRR claims involve a combination of state and federal rules and are more procedurally complex than standard car accident claims. If a government-operated vehicle was involved, a Notice of Claim must typically be filed within 90 days of the accident. Missing that deadline can permanently eliminate your right to recover against that defendant. Contact an attorney immediately if a railroad or government vehicle was involved in your crash.
How long do I have to file a car accident lawsuit on Long Island?
In most cases, New York’s statute of limitations gives you three years from the date of the accident to file a personal injury lawsuit. However, if a government entity or municipal vehicle was involved, the timeline is much shorter. A Notice of Claim must be filed within 90 days, and the lawsuit itself must follow within one year and 90 days. Do not wait to get legal advice if a public entity may be a defendant in your case.
What is the serious injury threshold and how does it affect my Long Island case?
New York’s serious injury threshold under Insurance Law Section 5102(d) determines whether you can sue the at-fault driver for pain and suffering beyond your no-fault benefits. Qualifying injuries include bone fractures, significant disfigurement, permanent limitation of a body organ or member, significant limitation of use of a body function or system, and injuries that prevented you from performing your normal daily activities for at least 90 of the first 180 days after the accident. Insurance companies frequently challenge whether injuries meet this standard, and having medical documentation aligned with the legal definition from early in your treatment is critical.
Should I call a lawyer before giving a statement to my insurance company?
Yes, always. Your own insurance company is not on your side in the way you might expect. Adjusters are trained to ask questions designed to limit your recovery, and anything you say in a recorded statement can be used to reduce or deny your claim. Michael J. Redenburg offers a free personal consultation and can advise you on exactly what to say and what not to say before you speak to anyone from any insurance company.
