Signs You May Be Suffering from Post-Traumatic Stress after a Car Accident

Legally Reviewed by Frank Marsalisi on August 31, 2026

If sudden panic behind the wheel, recurring nightmares about the crash, or a lingering sense that danger is still close by have followed your car accident, you may be dealing with post-traumatic stress disorder rather than ordinary shock that fades with time. Every year, there are over six million car crashes in the United States, and researchers who studied a group of collision survivors found that nearly 39 percent met the clinical criteria for post-traumatic stress disorder within months of the crash, according to a study published in The Journal of Nervous and Mental Disease. That makes motor vehicle collisions one of the most common causes of PTSD in the general population.

PTSD is a recognized anxiety disorder that can develop after a traumatic event involving a real or perceived threat of death or serious injury, and it can cause lifelong anguish, missed work, and strained relationships when it goes unaddressed. In Florida, an attorney may be able to help you pursue compensation for that mental anguish and any related lost wages, not just your physical injuries. If you are suffering from PTSD after a motor vehicle accident, Attorney Frank P. Marsalisi and our team at Marsalisi Law can review your personal injury case and help you understand what your claim may be worth.

What PTSD After a Car Accident Can Look Like

After a car accident, it is normal for your emotions to run high. Shock, fear, confusion, and anger are all common reactions in the days that follow. However, when those feelings intensify over time rather than fade, you may be experiencing something more persistent than ordinary stress. According to the National Institute of Mental Health, PTSD symptoms generally fall into four categories: re-experiencing the event, avoidance, negative changes in mood or thinking, and heightened arousal or reactivity. You may be dealing with PTSD if you are experiencing any of the following signs:

• Insomnia or frequent nightmares about the collision;
• Flashbacks or intrusive memories of the crash;
• Guilt, depression, or emotional numbness related to the accident;
• Anxiety about driving, riding in a car, or approaching the accident scene;
• Irritability or a heightened startle response;
• Avoiding people, places, or routes that remind you of the crash; and
• Withdrawing or feeling disconnected from family and friends.

Not everyone who develops these symptoms was in a catastrophic crash. Research on motor vehicle accident survivors has found that the strongest predictor of PTSD six months after a collision was the perception that your life was in danger during the event, based on a 2012 study on the topic. You may also face a higher likelihood of developing PTSD if you have a personal or family history of anxiety or depression, lacked a strong support system after the crash, had been through a traumatic event before the accident, or worked in a role, such as a first responder, that involves repeated exposure to trauma.

PTSD after a crash is commonly treated through a combination of psychotherapy and medication, and approaches such as cognitive behavioral therapy and exposure therapy have been shown to help many people process the trauma and reduce their symptoms over time. This is general public-health information, not a diagnosis, and only a licensed mental health professional can evaluate your specific symptoms.

Why Psychological Injury Is a Real and Compensable Harm

Florida law does not limit a car accident claim to broken bones, torn ligaments, or medical bills. Emotional distress and psychological conditions like PTSD are recognized categories of harm in a personal injury case, and a person who develops PTSD after a crash can potentially pursue compensation for that harm even when their physical injuries were relatively minor. Our firm has reviewed cases where the visible damage to a vehicle looked minor while the psychological toll on the person inside was significant and lasting, which is part of why we treat mental anguish as seriously as we treat a fracture or a herniated disc.

That said, psychological injury claims are inherently more subjective than a broken bone visible on an X-ray, which is exactly why documentation matters so much. Insurance companies routinely scrutinize claims for emotional distress more closely than claims for physical injury, and a claim that is not well supported can be undervalued or denied. Understanding how this type of harm gets proven, and what a full damages picture actually looks like, can help you protect the value of your claim from the start.

How PTSD Is Documented and Proven in a Car Accident Claim

Because psychological injury does not show up on an X-ray, the strength of this part of a claim depends heavily on consistent, well-documented treatment. Records of visits to a therapist, psychologist, or psychiatrist can provide concrete evidence of the emotional impact of the crash, and a formal diagnosis from a licensed mental health provider carries far more weight with an insurance adjuster or a jury than your own description of how you feel.

Several forms of evidence typically come together to support a PTSD or emotional distress claim after a car accident, including the following.

Common Sources of Documentation

Treatment records from a therapist or psychiatrist that describe your diagnosis, symptoms, and progress over time tend to carry the most weight. Prescriptions for anxiety, depression, or sleep disturbances can further show that a medical provider considered your symptoms serious enough to warrant treatment. Testimony from a qualified mental health professional can connect your symptoms directly to the crash rather than to some other cause in your life, and consistent follow-up appointments demonstrate that your symptoms are ongoing rather than a passing reaction.

Journal entries, missed workdays, and statements from family members who have observed the change in you can also corroborate what the clinical records show. Gaps in treatment, on the other hand, tend to work against a claim, since an insurer may argue that a lapse in care means the condition resolved on its own.

We often coordinate with our clients’ treating providers to make sure this evidence is organized and presented clearly, since a well-supported psychological injury claim looks very different from a handful of vague complaints. Our overview of psychological injuries in a personal injury case goes into more detail on how these claims are evaluated.

Economic and Non-Economic Damages in a Florida Car Accident Case

A personal injury claim in Florida is generally built around two categories of damages. Economic damages cover the costs you can calculate and document, such as medical bills, therapy expenses, prescription costs, and lost wages from time away from work. Non-economic damages, sometimes called general damages, cover harm that does not come with a receipt, including pain and suffering, emotional distress, loss of enjoyment of life, and the psychological toll of a diagnosis like PTSD.

Both categories matter, and treating them as connected rather than separate often produces a more complete claim. A claim that documents only medical bills and lost wages may understate what a crash actually cost someone who now struggles to drive, sleep, or feel safe in everyday situations. We build our clients’ claims to reflect both the financial impact of a collision and the harder to quantify toll it takes on daily life, and our breakdown of compensation after a Florida car accident explains how these categories typically fit together in a claim.

Timing matters here as well. Florida shortened its statute of limitations for most negligence claims, including car accident cases, from four years to two years for accidents occurring on or after March 24, 2023, under a 2023 change to state law. Crashes that happened before that date generally still fall under the older four-year window. Because the applicable deadline depends on when your accident occurred, it is worth confirming your specific timeline with an attorney rather than assuming which rule applies, since missing the deadline can potentially bar your claim entirely regardless of how strong the underlying evidence is.
