Rear-End Collision and the Seatbelt Defense

Maria is driving southbound on a four-lane road in Florida at 45 mph in the right lane. A delivery van driven by Omar, who is texting, fails to brake and rear-ends Maria's car at approximately 40 mph. Maria was not wearing her seatbelt. The impact throws her forward; she sustains a fractured wrist and a concussion. Her medical bills total $85,000, and she misses four months of work as a bartender, losing $22,000 in wages. Omar's insurer concedes liability for the collision but argues Maria's failure to wear a seatbelt contributed to her injuries and should reduce her recovery. At trial, Omar's biomechanical expert testifies that a seatbelt would have prevented the wrist fracture but would not have prevented the concussion. The jury finds Omar 100% at fault for the collision and assigns Maria 20% fault for her injuries. The jurisdiction follows a modified comparative fault regime.

1. Omar argues Maria's comparative fault should reduce her total recovery by 20%. Evaluate that argument under Florida law, including the seatbelt defense.

Florida recognizes a seatbelt defense under Fla. Stat. § 316.614(4)(b): failure to wear a seatbelt is admissible on the issue of comparative negligence but is not admissible on the issue of liability, and it does not go to the happening of the accident - only to the extent of injury. So the jury's 20% allocation must be confined to injury causation, not to the collision itself. The jury's finding that Omar was 100% at fault for the collision is consistent with that rule.

Under Florida's modified comparative fault statute (§ 768.81), a plaintiff's recovery is reduced by the percentage of fault attributable to the plaintiff, provided the plaintiff's fault is not greater than the defendant's. Here Maria's 20% is far below Omar's 80% (or 100% on liability), so she is not barred.

The reduction applies only to damages caused by the conduct the jury faulted - i.e., the wrist fracture. The concussion was unaffected by the seatbelt, so the 20% reduction should not apply to concussion-related damages. A properly instructed jury must apportion by injury, not by a blanket percentage on the total verdict.

2. Assume the jury returns special verdicts: $30,000 for the wrist fracture, $40,000 for the concussion, and $22,000 for lost wages. Compute Maria's recoverable damages and explain each step.

Step 1 - Separate the injury categories.

  • Wrist fracture: $30,000 (seatbelt-related).
  • Concussion: $40,000 (not seatbelt-related).
  • Lost wages: $22,000.

Step 2 - Apply comparative fault only to the seatbelt-caused injury.

  • Wrist: $30,000 × 80% = $24,000.
  • Concussion: $40,000 × 100% = $40,000.

Step 3 - Lost wages. Wages lost from the four-month absence are attributable to the accident, not to the seatbelt failure. Omar conceded liability for the collision. The 20% seatbelt reduction should not be applied to wage loss unless the evidence shows the seatbelt failure prolonged the absence. On these facts it does not, so the full $22,000 is recoverable.

Step 4 - Total. $24,000 + $40,000 + $22,000 = $86,000.

Caveat. If the court instead treats comparative fault as a single global percentage applied to the entire verdict, the result would be $92,000 × 80% = $73,600. The better view under § 316.614(4)(b) is injury-specific apportionment, which yields $86,000. Maria's counsel should object to a global instruction and request a special verdict form segregating the seatbelt-related injury.
