How to Handle a Car Accident on Long Island (Step-by-Step 2026 Guide)

Last reviewed May 15, 2026 by Dr. Dao Yuan Han, Data Editor & Lead Analyst, Long Island Traffic. PhD Mathematics · Differential Geometry · 10,000+ NY Open Data crash records analyzed. Informational only — not legal advice.

The first ten minutes after a Long Island car accident decide most of what follows. We know this because we have analyzed thousands of incident reports from 511NY, the New York State Police, the Nassau and Suffolk County Police Departments, and the public legal record. The drivers who recover fastest — medically, financially, and procedurally — are not the ones who know the most about New York Vehicle and Traffic Law. They are the ones who execute a calm, ordered sequence: stop, breathe, document, report, treat, file.

This guide is that sequence. It is built from our accident archive, our Know Your Rights legal library, and the structural analysis in our data-driven dangerous roads report. It is informational. For your specific situation, consult a licensed New York attorney.

At a Glance: The Long Island Crash Response Sequence

Within the First 10 Minutes — DO

• Stop your vehicle and turn on hazard lights
• Check yourself, then passengers, then the other vehicle’s occupants
• Call 911 — even for minor crashes
• Move to safety if vehicles are drivable; stay in the vehicle with seat belt on if not
• Photograph everything: damage, position, plates, licenses, insurance cards, witnesses

Within the First 10 Minutes — DON’T

• Apologize or admit fault, even reflexively
• Discuss what happened with the other driver beyond exchanging information
• Move vehicles before police arrive if the crash is anything more than minor
• Leave the scene — NY VTL §600 requires you to stop
• Refuse a medical evaluation because you “feel fine”

Within 10 Days

• File the MV-104 with NY DMV (required by VTL §605 if injury or > $1,000 damage)

Within 30 Days

• File the NF-2 No-Fault application with your own auto insurer (required by Insurance Law §5103)

Hard Rules

• Get to a doctor the same day or next morning
• Do not give a recorded statement to the other driver’s insurer
• Do not sign any release until your treatment reaches maximum medical improvement

Step 1: Stop, Breathe, Check for Injuries

Adrenaline floods your system the instant of impact. You will underestimate your injuries and overestimate your composure. Do this anyway:

1. Stop the vehicle. NY VTL §600 requires you to stop after any accident that causes property damage or injury. Leaving is a separate crime — see our hit-and-run rights guide.
2. Check yourself. Move your hands and feet. Notice any sharp pain, dizziness, neck stiffness.
3. Check passengers.
4. Check the other vehicle’s occupants if you can do so safely.

If anyone is unresponsive or visibly seriously injured, call 911 immediately and do not move them unless there is an active fire risk.

Step 2: Move to Safety — Or Stay Put

This decision varies by where you are on Long Island. The wrong decision kills people.

If You Are on a Parkway

On the Southern State, Northern State, Wantagh, Meadowbrook, or Sagtikos parkway:

• If the vehicles are drivable and the crash is minor, move to the shoulder or off the parkway at the next exit.
• If the vehicles are not drivable, stay inside the vehicle with your seat belt fastened. The data on secondary impacts — drivers who fail to see a stalled vehicle in time — is unambiguous. Standing outside a stalled car on a Long Island parkway is one of the most dangerous things a driver can do.

If You Are on the LIE or Sunrise Highway

Same rule. The LIE and Sunrise Highway have higher traffic volumes and faster closing speeds than the parkways. If your vehicle is drivable, move to the shoulder or an exit. If it is not, stay inside.

If You Are on an Arterial or Side Street

Move to the side of the road if possible. Turn on hazards. Set up flares or a reflective triangle if you have them.

Step 3: Call 911

Always. Even for minor crashes. The reasons:

• A police report creates a contemporaneous official record. Insurance disputes turn on this document. Without it, you and the other driver have competing memories.
• NY requires a report for any accident involving injury or more than $1,000 in damage — most Long Island crashes are above this threshold by the time both vehicles are evaluated.
• Police can call EMS for injuries you do not yet realize you have.

Long Island Jurisdiction Rules

Different agencies respond depending on the road:

Tell the dispatcher the road, direction of travel, and nearest exit or cross-street. Most parkway and expressway responses use mile-marker references, not addresses.

Step 4: Document Everything — Use Your Phone

The strongest evidence in any insurance dispute is the contemporaneous photograph. Take more pictures than you think you need.

What to Photograph

• Vehicle damage — all four sides of every vehicle involved, close-ups of impact points, plus wider shots showing relative position before vehicles are moved.
• The scene — skid marks, debris, traffic signals, signage, lane markings, weather, road surface conditions.
• The other driver(s) — license plate, driver’s license, insurance card. Photograph them; do not transcribe.
• Witnesses — names and phone numbers. A single independent witness can outweigh every photograph.
• Yourself, if injured. Visible injuries should be photographed at the scene and again every day for the first week. Soft-tissue injuries often present more visibly on day 2 or 3.

Useful Data to Record in Notes

• Time and date
• Exact location (road, direction, exit, mile marker)
• Speed estimate before impact
• Weather and road conditions
• Whether traffic signals were green, yellow, or red
• Whether the other driver appeared impaired

Step 5: Exchange Information — Carefully

You are required by NY law to exchange:

• Name and address
• Driver’s license number
• Vehicle registration
• Insurance carrier and policy number

You are NOT required to:

• Discuss fault
• Apologize
• Speculate about what happened
• Give a recorded statement

Statements at the scene — including casual ones like “I didn’t see you” or “I’m so sorry” — appear in claim files later and are extremely difficult to walk back. Stick to the required exchange and police interview. Save the analysis for your attorney.

Step 6: Choose the Right Hospital

For serious injuries, the choice of hospital matters for treatment quality and trauma-center designation. EMS will route you to the closest appropriate trauma center, but for non-life-threatening injuries you can request a specific hospital.

Long Island Trauma Centers

For pediatric trauma, Cohen Children’s Medical Center (New Hyde Park) and Stony Brook Children’s are the regional referrals.

Why Same-Day Treatment Matters

Two reasons same-day or next-morning medical evaluation matters, even for “minor” accidents:

1. NY Insurance Law §5103 requires injury treatment records to support a PIP claim. Without an early medical visit, the insurer has strong grounds to argue your injuries were not accident-related.
2. The 30-day no-fault filing clock starts immediately. Missing the medical timeline gives the insurer leverage even when your filing is on time.

Step 7: Notify Your Insurance Carrier

Call your own carrier — not the other driver’s — within 24 hours. Most policies require “prompt notice” and insurers interpret that strictly.

What to Say

• The basic facts: when, where, who was involved, what was hit.
• That you are filing a no-fault claim under PIP.

What NOT to Say

• Anything assigning fault.
• A recorded statement, unless you understand exactly what you are agreeing to.

The other driver’s insurer will often call and ask you for a recorded statement. You are under no obligation to give one. Decline politely. If you have an attorney, refer them to the attorney. If you do not, refer them to your own carrier.

Our Know Your Rights: Insurance Claims guide walks through the no-fault and liability process in depth. The companion editorial, How to File an Insurance Claim After a Long Island Car Accident, covers the paperwork sequence in detail.

Step 8: File the MV-104 with NY DMV — Within 10 Days

For any Long Island accident involving injury or property damage over $1,000, you must file form MV-104 with the NY DMV within 10 days. This is required by VTL §605. It is separate from the police report and separate from your insurance claim.

• File online at dmv.ny.gov or by mail
• The form is one page
• Failure to file can result in driver’s license suspension

Step 9: File the NF-2 No-Fault Application — Within 30 Days

This is the single most important deadline in the New York auto insurance system. You have 30 days from the date of the accident to file form NF-2 (Application for No-Fault Benefits) with your own auto insurance company.

What the NF-2 Covers

• Your demographic information
• A description of the accident
• A list of injuries
• Authorization for the insurer to obtain medical records
• A list of medical providers you have seen or plan to see
• Information about your employment, if you are claiming lost wages

How to Submit

• Use certified mail or the insurer’s official electronic portal so you have a date-stamped record.
• Keep a copy.
• If your insurer’s NF-2 form is unavailable, NY DFS provides a generic version every insurer must accept.

Penalty for Missing the Deadline

Insurers can — and do — deny claims for late filing under 11 NYCRR §65-1.1. There are extension provisions for “good cause,” but they are narrowly applied. Treat the 30-day deadline as absolute.

Step 10: Follow Treatment, Save Documentation, Decide About an Attorney

Follow the Treatment Plan

Gaps in treatment — particularly gaps of more than 30 days — give insurers leverage to argue you have recovered or your injuries were not serious. NY’s “serious injury threshold” (Insurance Law §5102(d)) is the standard your case will be measured against if you pursue a liability claim. Consistent treatment supports that threshold; gaps undermine it.

Save Everything

• Police report (request from State Police using form MV-198C if needed)
• MV-104 copy
• NF-2 copy
• Every medical record, bill, prescription receipt
• Every wage verification or lost-time document
• All photographs from the scene and over time
• All correspondence with insurers (email is preferred — it creates a paper trail)

When to Hire a Lawyer

You may not need one for a minor property-damage-only crash between two insured drivers. You probably do need one if:

• You have any injury beyond minor soft-tissue
• The other driver was uninsured (your UM/SUM coverage is in play)
• The crash involved a commercial vehicle, taxi, or rideshare
• The crash was a hit-and-run — see our hit-and-run rights guide
• The crash involved a pedestrian or cyclist — see our pedestrian rights guide
• The other vehicle was a truck — see our truck accidents rights guide
• The insurer denies or significantly underpays your no-fault claim

The standard NY personal injury fee structure is contingent — you pay only if you recover. Initial consultations are free.

Long Island Specifics That Catch People Off Guard

Parkway Accidents Are Usually State Police Jurisdiction

Nassau County PD and Suffolk County PD typically do not respond to the parkways or the LIE. To request a State Police accident report, use NY DMV form MV-198C.

No-Fault Claims Go to Your Own Carrier Even If You Were Not at Fault

This is the most counterintuitive feature of New York’s system. PIP medical bills and lost wages are paid by your own insurer regardless of fault. The at-fault driver’s insurer only enters the picture for property damage and (if you cross the serious-injury threshold) pain-and-suffering.

NY’s Minimum Liability Limit Has Not Been Updated Since 1974

The minimum is $25,000 / $50,000 — the same as it was 52 years ago. It is wildly insufficient for any serious Long Island accident. If you have not reviewed your own policy in the last few years, the most important coverage to increase is uninsured / underinsured motorist (UM/SUM).

Hit-and-Run Has Specific 24-Hour Rules

The physical-contact requirement for UM coverage in hit-and-run cases and the 24-hour police report deadline are easy to miss. Read our hit-and-run rights guide if this applies to you.

What NOT to Do — The Mistakes That Cost the Most

1. Apologizing or Admitting Fault at the Scene

Even reflexive apologies become evidence. Stick to the required information exchange.

2. Skipping Medical Evaluation Because “I Feel Fine”

The cost of skipping it is enormous. Adrenaline masks injuries for hours. Soft-tissue symptoms peak on day 2 or 3.

3. Giving a Recorded Statement to the Other Driver’s Insurer

You are not required to. Politely decline.

4. Posting About the Accident on Social Media

Insurers monitor public posts. A photo of you smiling at a barbecue 48 hours later becomes “evidence” of recovery in the claim file.

5. Accepting a Quick Settlement Before You Know the Full Extent of Your Injuries

Once you sign a release, the claim is closed. New injuries discovered later are not covered.

6. Missing the 30-Day NF-2 Deadline

This is the single most expensive paperwork mistake.

7. Missing the 10-Day MV-104 Deadline

The penalty (license suspension) is administrative but real.

8. Letting Treatment Gaps Open

Gaps of more than 30 days give insurers grounds to terminate benefits.

9. Treating Without Documenting the Crash Connection

Every medical visit should reference “motor vehicle accident on [date]” in the chief complaint. This is the link that keeps PIP paying.

10. Standing Outside Your Vehicle on a Parkway

The single most dangerous post-crash decision. If your vehicle is not drivable, stay inside with the seat belt on until first responders arrive — unless there is fire risk.

FAQ: Handling a Car Accident on Long Island

What if the other driver does not have insurance? Your own UM/SUM coverage applies. NY requires every auto policy to include uninsured motorist coverage at minimum $25,000 / $50,000. See our insurance claims rights guide.

What if I am the at-fault driver? PIP still pays your medical bills regardless of fault. You may also have collision coverage to repair your own vehicle. The at-fault designation matters most for the other driver’s liability claim against you.

Do I have to call the police for a fender-bender in a parking lot? NY law does not strictly require a police report for parking-lot incidents with no injury and minor damage. But filing the MV-104 within 10 days is still required if damage exceeds $1,000 — which most modern bumper repairs do.

What if the other driver leaves the scene? Hit-and-run. Call 911 immediately. Note the plate, vehicle description, and direction of travel. NY’s UM coverage applies in hit-and-run cases if there was physical contact between vehicles. Read our hit-and-run rights guide for the specific 24-hour reporting rules.

Can I refuse a breathalyzer or field sobriety test? You can, but NY has implied consent (VTL §1194) — refusal results in automatic license suspension and is admissible in court. If you have not been drinking, comply. If you have been, contact an attorney before saying anything else.

What if the airbags did not deploy? Airbags are calibrated to deploy at specific impact thresholds and angles. Non-deployment in a low-speed crash is normal. Non-deployment in a higher-speed crash where deployment was expected may be grounds for a product-liability claim — preserve the vehicle and consult an attorney.

How long does an insurance company have to process my claim? Under NY Insurance Law §5106, 30 days from receipt of all required verification. After 30 days, the claim becomes overdue and the insurer owes 2% per month interest on the overdue amount.

What is the “serious injury threshold” in New York? Insurance Law §5102(d) defines it: death, dismemberment, significant disfigurement, fracture, loss of a fetus, permanent loss of use, permanent consequential limitation, significant limitation of a body function or system, or the “90/180 rule” (an injury preventing usual daily activities for 90 of the 180 days following the accident). If your injuries meet this threshold, you can pursue a liability claim for pain and suffering. If not, you are limited to PIP.

Is there a deadline to file a lawsuit? For personal injury claims in NY, the statute of limitations is generally three years from the date of the accident (CPLR §214). For wrongful death, two years from the date of death (EPTL §5-4.1). Different deadlines apply to claims against municipalities.

What if my crash involved a Long Island Rail Road train or platform? Claims against the MTA / LIRR follow different procedures. You typically must file a Notice of Claim within 90 days. See Public Authorities Law §1276. Contact an attorney immediately.

Where can I get my police report? For State Police reports (parkways and LIE): NY DMV form MV-198C. For Nassau County PD: visit any precinct or the NCPD records bureau. For Suffolk County PD: the SCPD records bureau in Yaphank. Local village PDs handle their own records.

Should I see a chiropractor or an MD first? Both are valid PIP-eligible providers. An emergency department visit on the day of the crash creates the clearest documentation chain. Specialist follow-up (orthopedist, neurologist, chiropractor) within the first week supports the treatment timeline.

What if my insurance carrier sends me to an Independent Medical Examination (IME)? You are required to attend under your policy and 11 NYCRR §65-3.5. The IME doctor is paid by the insurer, so the exam is rarely truly “independent.” Missing one without good cause is grounds for benefit suspension. If you disagree with the IME conclusion, you can contest it through no-fault arbitration through the American Arbitration Association — covered in detail in our insurance claim editorial.
