Florida's 51% rule: modified comparative negligence explained with Palm Beach County examples

Almost every injury claim in Florida includes an argument about the injured person’s own conduct. You were going a little fast. You looked at your phone. You were not in the crosswalk. Until 2023, those arguments could reduce what you recovered but could never wipe it out. Now they can. Understanding how Florida’s modified comparative negligence rule works is the clearest way to see why insurers fight so hard over percentages, and why small facts matter.

What changed in 2023, and what does “greater than 50 percent” mean?

HB 837, the 2023 tort reform law, added subsection (6) to Florida’s comparative fault statute, and the act applies it to negligence lawsuits filed after March 24, 2023. It says that in a negligence action, any party found greater than 50 percent at fault for his or her own harm may not recover any damages (Fla. Stat. § 768.81(6)). Before that, Florida used pure comparative negligence, where even a person 90 percent at fault could recover 10 percent of their damages.

The line falls just above the halfway mark. At 50 percent, you still recover half. At 51 percent, you recover nothing. That is why the change is commonly called the 51 percent rule.

Below the bar, your recovery is reduced by your share. If a jury finds your total damages and assigns you 20 percent of the fault, you collect 80 percent of that amount. At 35 percent, you collect 65 percent.

The rule does not apply to everything. Section 768.81(6) expressly excludes personal injury and wrongful death actions arising from medical negligence under chapter 766.

How would the rule play out in real Palm Beach County situations?

The examples below are illustrations of how arguments tend to go, not predictions. A jury hears the evidence and can land in very different places.

Situation	Arguments about the injured person’s fault	Why the percentage matters
A driver turning left from Okeechobee Boulevard onto Australian Avenue is hit by a car that ran a stale yellow light	The turning driver should have waited; the other driver says the light was still yellow	If the turning driver is found 40 percent at fault, recovery is reduced by 40 percent; at 55 percent, nothing
A pedestrian crosses Forest Hill Boulevard mid-block at night and is struck by a speeding driver	Pedestrians must yield outside crosswalks (Fla. Stat. § 316.130); the driver was going well over the limit	Speed and lighting evidence can keep the pedestrian’s share below 50 percent
A shopper slips on a spilled drink at a store near The Gardens Mall while reading a text	The spill was visible; the shopper was distracted	Video showing how long the spill was there can shift fault to the store
A driver not wearing a seat belt is rear-ended on I-95 near Palm Beach Lakes Boulevard	Failure to buckle up may be considered evidence of comparative negligence (Fla. Stat. § 316.614(10))	The defense must connect the missing belt to the injuries, not just point it out
A motorcyclist rides between lanes of stopped traffic on Southern Boulevard and is struck by a car changing lanes	Riding between lanes of traffic is prohibited in Florida (Fla. Stat. § 316.209(3))	The violation may weigh heavily, but the lane-changer’s failure to look still counts

Do the defendants also get their own percentages?

Yes. Florida apportions fault among everyone whose negligence contributed, and judgment is entered against each party based on its own share, not on joint and several liability (Fla. Stat. § 768.81(3)). In a three-car crash on the Turnpike, a jury might assign 10 percent to you, 60 percent to one driver and 30 percent to another. Each defendant pays only its share of the damages. If one of them has no insurance, the others do not cover that portion.

Defendants also try to put blame on people who are not in the lawsuit, sometimes called nonparties, such as a driver who caused the chain reaction and left. The statute allows that only if the defendant pleads it and then proves the nonparty’s fault at trial. Your own percentage is still compared with everyone else’s combined. So the 51 percent question is whether your share is greater than half of all the fault in the case, not whether you were more careless than any single defendant.

What evidence moves the percentages?

Fault percentages are not assigned by formula. They come from the evidence, and the evidence that tends to matter most is the kind that disappears first:

• dash-cam and nearby business video, which often shows lane position, signals and speed better than any witness
• vehicle event data recorder downloads, which capture speed and braking in the seconds before a crash
• signal timing records for intersections along corridors like Okeechobee Boulevard and Military Trail
• the investigating officer’s measurements and photographs
• independent witnesses, especially people who were not in any of the vehicles
• in a fall case, the store’s video, inspection logs and prior incident records

Statements matter too. A casual remark at the scene, such as “I didn’t see him,” or a recorded statement given to the other side’s insurer can be quoted back to assign you a larger share. It is fine to be honest. It is not wise to guess.

How does the rule affect settlement offers?

Insurers estimate fault before they make an offer. An adjuster who believes you are at or near 50 percent may offer very little, betting that the bar will apply at trial. Pushing the evidence in the other direction, even by a few percentage points, can change the value of a claim more than any other single factor. That is why much of the early work in a Palm Beach County injury case is gathering the proof that keeps the injured person’s share where it belongs.
