Yes. Post-traumatic stress disorder is a recognized medical condition. It can develop after a car accident, and it is more common than most people realize.
A person can walk away from a collision with no broken bones and no visible injuries. They may still develop intrusive flashbacks. Severe anxiety while driving is common. So are sleep disruption, hypervigilance on the road, and emotional responses that interfere with daily life for months or years after the event.
PTSD after a car accident is not a sign of weakness. It is a diagnosable psychiatric condition with specific clinical criteria. Under New York law, it can be the basis of a personal injury claim against the driver who caused the accident. But recovering money for PTSD requires meeting a legal threshold that does not apply to physical injuries. Understanding that threshold matters.
How PTSD develops after a car accident
PTSD occurs when the brain's response to a traumatic event does not resolve on its own. After a serious car accident, it is normal to feel shaken, anxious, or on edge for days or even weeks. For most people, those reactions fade. For some, they do not. The anxiety persists. The flashbacks continue. Driving becomes difficult or impossible. Sleep is disrupted by nightmares about the accident. Everyday situations can become triggers. The sound of brakes, an intersection that resembles the accident scene, a car approaching from the side: each can set off intense fear or panic.
A PTSD diagnosis requires symptoms that last more than one month. They must also significantly impair daily life, work, or relationships.
A psychiatrist or psychologist makes the diagnosis through a clinical evaluation. They use the criteria in the DSM-5.
That evaluation looks at four symptom clusters. The first is intrusive re-experiencing of the event. The second is avoidance of reminders. The third is negative changes in mood and cognition. The fourth is heightened arousal and reactivity.
The serious injury threshold in New York
New York is a no-fault state. After a car accident, your own insurance pays your medical bills and lost wages up to the policy limits through Personal Injury Protection. It does not matter who caused the crash. To sue the other driver for pain and suffering, your injuries must meet the serious injury threshold under Insurance Law Section 5102(d).
Section 5102(d) lists several categories of serious injury. One is permanent loss of use of a body organ or member. Another is significant limitation of use of a body function or system. A third covers injuries that stop a person from doing most normal daily activities. That limitation must last at least 90 of the first 180 days after the accident.
PTSD can qualify under more than one serious injury category. If the condition is chronic, it may meet the significant limitation category. That category requires records showing long-term limits on your ability to function. A mental health professional must back the claim with specific clinical findings.
The medical evidence required for a PTSD claim
A PTSD claim requires more than saying you feel anxious after the crash. It requires a formal diagnosis from a psychiatrist or psychologist. That diagnosis must come from a clinical evaluation. The evaluation records your specific symptoms. It notes when they started and how long they have lasted. It captures how severe they are and how they affect your daily life.
The treating mental health professional should document the frequency and content of intrusive thoughts or flashbacks. They should record the specific situations the patient avoids, such as driving, certain roads, or riding as a passenger. Changes in sleep patterns matter. So do changes in mood or emotional state. Any impact on work, relationships, or daily activities should be noted as well. Standardized assessment tools like the PCL-5 (PTSD Checklist) or the CAPS-5 (Clinician-Administered PTSD Scale) provide objective measurements. Those measurements strengthen the claim.
If you are not seeing a mental health professional after the accident, start now. The medical record is the evidence your case is built on. A gap between the accident and your first mental health visit gives the defense an argument. They can claim your symptoms are not as severe as you say. They can also argue something other than the accident caused them.
PTSD alongside physical injuries
PTSD often develops alongside physical injuries from the same accident. Someone who suffered a fracture, a back injury, or a traumatic brain injury may also develop PTSD from the collision itself. When both conditions are present, the combined impact on a person's life is greater than either condition alone. A personal injury claim can reflect that combined impact in the damages sought.
PTSD can also make physical recovery harder. A person who is afraid to leave the house may miss physical therapy appointments. A person whose sleep is disrupted by nightmares may heal more slowly. The interaction between the psychological and physical conditions is part of the damages picture.
PTSD without physical injuries
A PTSD claim does not require physical injuries. Someone who survived a severe collision, witnessed a fatality, or faced a genuine threat to their life can develop PTSD without a single physical injury. The challenge is meeting the serious injury threshold. The defense will argue that a person who walked away without a scratch could not have been seriously affected.
A psychiatrist's diagnosis based on a clinical exam carries weight. Standardized test scores, treatment records, and records of daily limits all back it up. That combination is what pushes past doubt about the condition. The medical evidence has to show the injury is real.
What damages are available for PTSD from a car accident
If the serious injury threshold is met, several types of damages become available. Past and future mental health treatment costs can be recovered. Future care costs may be included too. Lost wages may be recovered if PTSD kept you from working. Pain and suffering covers emotional distress. It also covers the reduced quality of life PTSD can cause. Loss of enjoyment of life may apply if PTSD has limited activities you once enjoyed.
PTSD touches every part of daily life. A person who cannot drive, cannot sleep, or cannot ride in a car without panic has suffered real harm. Years of heightened anxiety after a crash are damages the medical evidence can quantify.
How Schwartzapfel Holbrook handles PTSD claims from car accidents
We look at every car accident case for both physical and psychological harm. When a client shows PTSD symptoms, we connect them with a mental health professional. That provider documents the diagnosis with clinical findings and standard assessments. Those records then support the serious injury threshold under Section 5102(d).
PTSD is an invisible injury. The defense will challenge it. The insurance company will minimize it. The medical evidence is what makes the case. Building that evidence early and thoroughly is how we approach every PTSD claim.
