US-New YorkWhat injuries meet the 'serious injury' threshold to sue in a car accident?
In New York, a 'serious injury' for car accident lawsuits includes death, dismemberment, significant disfigurement, fractures, loss of a fetus, permanent loss of use of a body organ or member, or a medically determined injury that prevents the injured person from performing substantially all of their usual activities for at least 90 days within 180 days of the accident.
What the Law Says
New York’s no-fault insurance system bars most personal injury lawsuits after car accidents—unless the injury meets the statutory 'serious injury' threshold defined in Insurance Law § 5102(d). This threshold is strict and narrowly interpreted.
To file a lawsuit for pain and suffering in New York after a car accident, your injury must qualify as 'serious' under the law—even if you have substantial medical bills or ongoing pain. The definition is not based on subjective experience but on objective, statutory categories.
The law lists eight specific types of injuries that automatically qualify. Some require permanence (e.g., dismemberment), while others depend on duration and documentation (e.g., inability to perform usual activities). Medical evidence—and often expert testimony—is required to prove eligibility.
Importantly, 'serious injury' is a legal term—not a medical diagnosis. A doctor may call an injury 'severe,' but unless it fits one of the statutory categories, it won’t meet the threshold for suing.
Statutory Text‘Serious injury’ means a personal injury which results in death; dismemberment; significant disfigurement; a fracture; loss of a fetus; permanent loss of use of a body organ, member, function or system; permanent consequential limitation of use of a body organ or member; significant limitation of use of a body function or system; or a medically determined injury or impairment of a non-permanent nature which prevents the injured person from performing substantially all of the material acts which constitute such person’s usual and customary daily activities for not less than ninety days during the one hundred eighty days immediately following the occurrence of the injury or impairment.

What Courts Have Said
New York courts consistently emphasize that plaintiffs bear the burden of proving a 'serious injury' by competent medical evidence—and that vague or conclusory statements are insufficient.
The Court held that MRI findings alone—without correlation to functional limitations or clinical examination—do not satisfy the 'significant limitation' standard under § 5102(d).
Established that 'permanent consequential limitation' requires proof of a meaningful, lasting impact on daily life—not just occasional discomfort or minor restrictions.
What to Do
Get prompt, detailed medical documentation—including diagnoses, imaging reports, treatment plans, and functional assessments.
Keep a daily log for 180 days tracking missed work, canceled obligations, and physical limitations (e.g., unable to lift, drive, or care for children).
Consult a New York auto injury attorney before settling with an insurer—they can assess whether your injury meets the serious injury threshold.
File any lawsuit within New York’s 3-year statute of limitations for personal injury (CPLR 214(5)), but act sooner—evidence and memories fade.
