How to Prove the 90/180-Day Rule in a New York Auto Accident Case

How to Prove the 90/180-Day Rule in a New York Auto Accident Case

On This Page

Why the 90/180-Day Rule Mattered in New York Crash Claims

Key Takeaways: Proving the 90/180-day rule required objective medical evidence showing a non-permanent injury prevented substantially all usual daily activities for at least 90 of the first 180 days post-crash. Strong claims relied on contemporaneous medical records, objective testing like goniometer range-of-motion measurements, and physician notes restricting specific tasks. Courts evaluated each serious injury category independently, so surviving on one category never guaranteed survival on the 90/180-day claim. As of May 27, 2026, this category was repealed from § 5102(d) as part of FY27 tort reform, applying to motor vehicle actions commenced on or after the effective date. Plaintiffs must now qualify under remaining categories such as fracture, significant disfigurement, or permanent/significant limitation of use. Anyone with pending or recent claims should continue documenting limitations and confirm how the repeal applies to their specific facts.

For years, the 90/180-day rule gave injured New Yorkers a path to sue at-fault drivers for pain and suffering. Under New York’s no-fault scheme, injured persons generally cannot recover non-economic damages unless the injury crosses a statutory threshold. The 90/180-day rule required that a medically determined injury of a non-permanent nature prevent performing substantially all material acts of usual and customary daily activities for at least 90 days within the first 180 days post-accident. Understanding how this category worked and what changed in 2026 is essential for Queens or NYC collision victims.

What the New York no-fault law serious injury threshold Requires

The threshold is defined by statute, not by how badly you feel. New York Insurance Law § 5102(d) sets out qualifying categories allowing injured NYC accident victims to step outside no-fault and sue for non-economic damages like pain and suffering. Meeting one category is enough, but each is evaluated independently. Review the full statutory text of New York Insurance Law 5102d through the State Senate.

Historically, the 90/180-day category appeared at the statute’s end. It covered medically determined injuries of non-permanent nature preventing substantially all material acts of usual and customary daily activities for at least 90 days during the 180 days immediately following the occurrence. This category was significant because it reached non-permanent injuries, potentially available to victims who did not suffer catastrophic or lasting harm. Because the statute required "non-permanent" injury, courts held that proof of purely permanent injury could not satisfy this category.

How Plaintiffs Proved the 90/180-Day Category

Proving this category required objective medical proof tied to daily-activity limitations. Once defendants met their initial burden, plaintiffs had to raise material issues of fact using objective, admissible medical proof. Courts looked for contemporaneous treatment records, physician findings, and credible evidence connecting the crash to genuine inability to function.

Evidence That Carried Weight

Strong claims relied on measurable, documented restrictions. Persuasive files typically included:

  • Contemporaneous medical records from days and weeks after the crash
  • Objective testing, such as goniometer range-of-motion measurements
  • Physician notes restricting work, lifting, driving, or household tasks
  • Clear, dated timelines showing limitations across at least 90 of the first 180 days

In one matter, a plaintiff’s expert used a goniometer to measure range of motion and found significant, permanent limitations, raising triable issues on other serious injury categories. That same proof did not automatically rescue the daily-activities claim.

Common Pitfalls That Sank Otherwise Valid Claims

Vague or conclusory statements often doomed the 90/180-day argument. In one decision, the court held that a plaintiff’s bill of particulars assertion of several days confined to bed and one month confined to home was insufficient to meet the burden under the 90/180-day disability category. Brief, undocumented confinement rarely satisfied the "substantially all" and "90 of 180 days" requirements, which courts read as curtailment of usual activities to a great extent rather than slight or merely uncomfortable limitation.

💡 Pro Tip: If a physician restricts your activities, ask that specific tasks you cannot perform and expected duration be written into your chart. Generic notes like "rest as needed" carry far less evidentiary weight.

A Recent Court Decision Shows the Stakes

A 2024 ruling illustrates how independently courts evaluate each serious injury category. The plaintiff’s shoulder and spine claims survived summary judgment, yet the daily-activities claim did not. The order granted defendants’ motion only as to plaintiff’s claims under the permanent loss of use and 90/180-day categories, and denied it in all other respects. Read the full published court order through the New York court reporter.

Surviving on one category does not guarantee survival on another. Though the treating physician’s report was sufficient to raise triable issues on right shoulder and lumbar spine injuries under other categories, the court separately granted dismissal of the 90/180-day claim. For deeper explanation of how these categories interact, see our overview of the serious injury threshold for NYC auto accidents.

The 2026 Repeal of the 90/180-Day Rule

A significant change took effect in 2026. As of May 27, 2026, the 90/180-day category was removed from § 5102(d). This elimination was part of a FY27 tort reform package applying prospectively to motor vehicle actions commenced on or after the effective date, with limited exceptions. Plaintiffs in covered cases must now qualify under remaining serious injury categories to pursue pain and suffering claims.

This does not mean older claims should be abandoned. Whether the repeal affects a particular case depends on timing, procedural posture, and fact-specific questions courts may interpret narrowly. Because the reform generally applies to actions commenced on or after its effective date, lawsuits already pending may continue under the prior standard. Anyone with pending or recent claims should keep documenting limitations and confirm how the change applies to their facts.

💡 Pro Tip: Statutory changes rarely answer every transitional question at once. If your lawsuit was already pending before the revision, the prior standard may still apply, so keep documenting your limitations.

Other Paths to Meeting the Threshold After the Change

With the 90/180-day rule gone, remaining § 5102(d) categories become primary routes to recovery. These include death, dismemberment, significant disfigurement, fracture, loss of fetus, permanent loss of use of a body organ, member, function or system, permanent consequential limitation of use of body organ or member, and significant limitation of use of body function or system. Many crash victims now focus proof on permanent and significant limitation categories.

Serious Injury Category General Focus of Proof
Fracture Imaging confirming a broken bone
Significant disfigurement Scarring or visible permanent change
Permanent loss of use Total, permanent loss of function
Permanent consequential limitation Lasting, measurable restriction
Significant limitation of use Meaningful, documented impairment

Objective medical evidence remains the foundation of any surviving category. Range-of-motion findings, diagnostic imaging, and consistent treatment records continue to drive outcomes. If hurt in Queens, a knowledgeable New York no-fault law serious injury threshold lawyer can evaluate which category best fits your injuries.

💡 Pro Tip: Gaps in treatment are one of the most common reasons insurers challenge serious injury claims. Consistent, documented care helps connect injuries to the crash.

How No-Fault Procedures Still Shape Your Case

Even outside the courtroom, the no-fault system affects your recovery and evidence trail. Basic economic loss under § 5102(a) is capped at $50,000 per person, covering: (1) all necessary expenses for medical, hospital, surgical, nursing, dental, ambulance, x-ray, prescription drug, and prosthetic services; psychiatric services, physical therapy, occupational therapy, and rehabilitation (when rendered pursuant to a referral); non-medical remedial care in accordance with a recognized religious method of healing; and any other professional health services; (2) loss of earnings from work up to $2,000 per month for up to three years from the date of the accident; and (3) other reasonable and necessary expenses up to $25 per day for up to one year from the date of the accident. Engaging with this system promptly helps build the medical record a lawsuit may later require.

No-fault disputes do not automatically defeat separate injury lawsuits. Under New York law, an arbitration award or court decision resolving a no-fault reimbursement dispute generally does not have collateral estoppel effect in a separate bodily injury lawsuit arising from the same accident. In practical terms, a no-fault denial generally will not, by itself, bar your tort claim, though outcomes remain fact-dependent.

Frequently Asked Questions

1. Does the 90/180-day rule still exist in New York?

Generally, no, for crashes governed by the revised statute. As of May 27, 2026, the 90/180-day category was removed from § 5102(d), generally applying to motor vehicle actions commenced on or after the effective date. Whether the change applies to specific older claims depends on timing and is best reviewed individually.

2. What counts as "substantially all" daily activities?

Courts required proof that injury prevented most usual and customary activities, not merely some. Brief confinement was generally not enough.

3. Can I still sue if my injuries are not permanent?

Possibly, but the analysis is harder without the 90/180-day category. You would generally need to meet another § 5102(d) category, typically requiring objective evidence of significant or permanent limitation.

4. Does a denied no-fault claim end my lawsuit?

Not automatically. Under New York law, no-fault reimbursement rulings are generally not given collateral estoppel effect in separate actions arising from the same occurrence.

5. How soon should I document my injuries?

As early as possible. Contemporaneous records created soon after the crash generally carry more weight than evaluations performed months later.

Protecting Your Right to Full Compensation

The serious injury threshold remains the gateway to recovering pain and suffering damages in New York auto cases, even after the 90/180-day rule’s repeal. Proving any qualifying category demands objective medical evidence, consistent treatment, and careful attention to evolving law. Because the 2026 changes are recent and courts interpret transitional questions narrowly, outcomes depend on specific case facts.
