Brain Injury After a Rear-End Crash and Florida's Tort Threshold

Attorney Answer

A traumatic brain injury can clear Florida's threshold for suing beyond no-fault benefits — but the statute turns on permanence proved by medical evidence, not on the diagnosis on the discharge paperwork. The work of a brain-injury claim is medical documentation over time, and it starts earlier than most people realize.

Two separate tracks run after a Florida crash. The first is your own personal injury protection coverage, which pays regardless of fault: 80 percent of reasonable and necessary medical expenses and 60 percent of lost income, subject to a $10,000 limit. It carries a hard front-end condition. Fla. Stat. § 627.736(1)(a) provides: "Medical benefits. — Eighty percent of all reasonable expenses for medically necessary medical, surgical, X-ray, dental, and rehabilitative services, including prosthetic devices and medically necessary ambulance, hospital, and nursing services if the individual receives initial services and care pursuant to subparagraph 1. within 14 days after the motor vehicle accident." Miss the 14 days and PIP benefits are at risk regardless of how the crash happened.

The second track is a claim against the driver who hit you, and that is where the threshold lives. Section 627.737(2) limits when a person covered by no-fault benefits may sue for pain and suffering, and its operative clause provides that "a plaintiff may recover damages in tort for pain, suffering, mental anguish, and inconvenience because of bodily injury, sickness, or disease arising out of the ownership, maintenance, operation, or use of such motor vehicle only in the event that the injury or disease consists in whole or in part of: (a) Significant and permanent loss of an important bodily function. (b) Permanent injury within a reasonable degree of medical probability, other than scarring or disfigurement. (c) Significant and permanent scarring or disfigurement. (d) Death."

Read that carefully, because it explains what a brain-injury claim has to prove. A concussion that resolves in a few weeks may not clear it. Persistent cognitive, memory, balance, vision, mood or sleep deficits, documented by treating specialists and stated as permanent within a reasonable degree of medical probability, are what clear it. That opinion has to come from your doctors, in your records, over time — it is not something a lawyer or a page can supply.

The other half matters just as much: the threshold gates only pain-and-suffering damages. Economic losses — medical expenses beyond the PIP limit, future care, and lost earnings — are not gated by it. Even a claim that never clears the threshold can still be a real economic claim.

On fault, a rear-end collision usually starts in a favorable place. Fla. Stat. § 316.0895(1) provides: "The driver of a motor vehicle shall not follow another vehicle more closely than is reasonable and prudent, having due regard for the speed of such vehicles and the traffic upon, and the condition of, the highway." Florida also applies a long-standing judge-made presumption that the following driver was negligent — it is a presumption the rear driver can rebut, not an automatic result.

What you can do

1. If you have not been evaluated, do it now, and say clearly that you hit your head. Fla. Stat. § 627.736(1)(a) conditions PIP medical benefits on initial services and care within 14 days of the crash.

2. Follow through on referrals — neurology, neuropsychology, vision or vestibular therapy. Gaps in treatment become the defense argument that the injury resolved.

3. Open a PIP claim with your own insurer and keep the explanations of benefits as they arrive.

4. Keep a dated log of symptoms and of what you can no longer do at work or at home, and bring it to appointments.

5. Request the crash report from the responding agency, and keep photographs of both vehicles.

6. Ask a Florida lawyer what medical proof the § 627.737(2) threshold requires on facts like yours, and when in your treatment that opinion is usually obtained.

Most lawyers offer a brief initial call at no cost, and a few minutes on your specific facts with someone who can hear the whole story is worth more than any general guidance, including this page.

⏱ Time limits apply. Fla. Stat. § 95.11 sets the negligence deadline and the period depends on when your crash happened: two years under § 95.11(5)(a) for claims accruing on or after March 24, 2023, and the former four-year period for accidents before that date. The 14-day PIP treatment condition in § 627.736(1)(a) runs far sooner than either. Nothing here computes your date — have a Florida attorney check it against your facts.
