Rear-End Collision in Florida: Fault, Laws, and What to Do (2026)

# Rear-End Collision in Florida: What You Need to Know

> **KEY FACTS:**
> – The rear driver is **presumed at fault** in Florida
> – PIP covers only $10,000 — for serious injuries, you may pursue the at-fault driver’s insurance
> – Florida’s **51% fault bar** applies
> – Statute of limitations: **2 years PI** (reduced from 4), **4 years PD**

**Important:** Florida’s entire car accident framework changed in 2023 under HB 837. Rear-end collision claims now work very differently from before.

## Fault in Florida Rear-End Collisions

Florida law presumes the **rear driver is negligent** in a rear-end collision. This presumption is based on the duty to maintain a safe following distance.

The presumption is **rebuttable** with evidence that the lead driver:
– **Brake-checked** or stopped suddenly without reason
– Had **non-functioning brake lights**
– **Reversed** unexpectedly
– Made an **unsafe lane change** in front of the rear driver
– **Stopped in a travel lane** without cause

### The 51% Bar Changes Everything

Under Florida’s new **modified 51% comparative fault rule** (Fla. Stat. § 768.81, as amended by HB 837):

– At **50% or less** fault: recover damages reduced by your fault %
– At **51% or more** fault: recover **nothing**

Even in rear-end collisions, if the lead driver contributed significantly (e.g., brake-checking), fault could be split. This is a major shift from Florida’s pre-2023 pure comparative system where fault could never bar recovery.

## What to Do After a Rear-End Collision in Florida

1. **Check for injuries and call 911**
2. **Move to safety** if vehicles are drivable
3. **Exchange information** — the rear driver’s BI liability coverage is what you will pursue
4. **Document the scene** — photos, witness info, dashcam if available
5. **Get a police report** — especially valuable for fault determination
6. **Notify your insurer** — even with PIP covering only $10,000, your collision/UM coverage may apply
7. **Seek medical attention** — critical with PIP covering only $10,000 covering initial medical costs

## Common Injuries

– **Whiplash** — the hallmark rear-end injury, often delayed
– **Concussions and TBI**
– **Herniated discs and back injuries**
– **Neck and shoulder injuries**
– **Soft tissue damage**

**Because PIP only covers $10,000:** You no longer have automatic $10,000 medical coverage. Documenting injuries from day one is critical for pursuing the at-fault driver’s insurance.

## Insurance and Compensation

### How to File

– **If you were rear-ended:** File a third-party claim against the rear driver’s **bodily injury liability** insurance (PIP $10,000 + PDL $10,000 minimum)
– **If PIP was your old plan:** It no longer exists. You need to file against the at-fault driver
– **UM/UIM coverage:** Your critical safety net if the rear driver is uninsured

### Because PIP only covers $10,000, Medical Bills Are Your Responsibility Until Settled

Under the old system, PIP paid medical bills within 30 days. Now, you may need to use:
– Your health insurance
– MedPay (if you have it)
– Medical liens (provider agrees to wait for settlement)

## Frequently Asked Questions

### Is the rear driver always at fault in Florida?
The rear driver is **presumed** at fault, but this can be rebutted. Under the new 51% bar, if the lead driver contributed significantly, the rear driver may still recover partial damages — or the lead driver’s recovery may be barred.

### How does this work with PIP covering only $10,000?
You now file against the at-fault driver’s PIP and property damage liability coverage. There is PIP covers only $10,000 in medical expenses (at 80%) from your own policy (unless you have MedPay).

### How long do I have to file?
**2 years** for personal injury (reduced from 4 under HB 837). 4 years for property damage.
