Florida Statute 627.727: Uninsured Motorist Coverage Rules

Florida uninsured motorist coverage is a component of your auto policy that pays for your injuries when the driver who hit you has no liability insurance, too little insurance, or an insurer that has gone broke. Under Florida Statute 627.727, every auto policy that includes bodily injury liability must also include UM coverage at matching limits unless you reject it or reduce it in writing on a form the state has approved.¹ Because Florida has one of the highest rates of uninsured drivers in the country, this coverage is often the only realistic source of compensation after a serious crash.

What UM Coverage Actually Pays For

UM coverage pays for bodily injury, illness, or death when the at-fault driver cannot fully pay for your losses. The statute uses the phrase “legally entitled to recover damages,” which means you still have to prove the other driver was at fault, and any defense that driver could raise in court can be raised by your own UM insurer.

Florida law treats four situations as “uninsured”:

The at-fault driver had no liability insurance at all.
The at-fault driver had insurance, but the company became insolvent.
The at-fault driver was underinsured, meaning their liability limits are not enough to cover your damages.
A non-family member was driving an insured vehicle under a policy that specifically excluded liability coverage for that person.

The underinsured category is the one most Floridians actually run into. Minimum liability limits are low, medical bills are not, and the gap can be enormous.

How Much UM Coverage You Have By Default

Your insurer has to offer UM coverage at the same limits as your bodily injury liability coverage. If you carry $100,000/$300,000 in liability, the starting point for UM is $100,000/$300,000. You can buy less, or buy none, but only by signing the right form.

If the insurer never got a valid signed rejection or reduction, the law presumes you have full stacked UM coverage at your bodily injury liability limits. That presumption is conclusive: the insurer cannot argue around it, even if you never paid a premium at that level.¹ If you have ever wondered whether your UM coverage is what you think it is, this is the first thing to check with your carrier.

Stacked Versus Non-Stacked Coverage

Stacking is the default in Florida, and it is the more protective option. Stacked coverage lets you add together the UM limits on every vehicle listed on your policy for a single accident. Three cars with $100,000 in UM coverage each gives you access to $300,000 in total UM benefits. Stacked coverage also tends to follow you off the vehicle, protecting you as a pedestrian, a cyclist, or a passenger in someone else’s car.

Non-stacked coverage is cheaper but comes with real limits that depend on what you were doing at the moment of the crash:¹

In your own insured vehicle, you get only the UM limit for that vehicle.
In someone else’s vehicle, you can reach the highest single-vehicle UM limit on any policy where you are a named insured or an insured family member, but only as excess over the vehicle owner’s UM.
In a vehicle you own but did not insure for UM, you have no coverage at all. This trap catches people who own multiple vehicles and buy UM on only some of them.
As a pedestrian or cyclist, you can pick any single-vehicle UM limit from your policy.

Once you elect non-stacked coverage, that election carries forward through renewals and replacement policies. Changing back to stacked coverage requires an affirmative request and the higher premium that goes with it.²

How UM Payouts Are Calculated

Florida UM coverage is gap coverage. It pays the difference between your total damages and what is available from other sources, up to your UM limit. Those other sources include the at-fault driver’s liability insurance, workers’ compensation, personal injury protection, and any medical payments coverage on your own policy. The statute prohibits UM from duplicating those benefits.²

An example makes the math concrete. Say your damages total $200,000. The at-fault driver carries $50,000 in bodily injury liability. You carry $100,000 in UM. Your UM insurer gets credit for the full $50,000 in liability limits, leaving $150,000 in remaining damages. Your UM pays up to its $100,000 limit against that balance. You recover $150,000 total, and $50,000 of your loss goes uncompensated. That credit for the at-fault driver’s full policy limits applies even if you actually settled with that driver for less.

How to Reject or Reduce UM Coverage

Rejecting UM coverage or choosing limits lower than your liability limits requires a form approved by the Florida Office of Insurance Regulation. The form has to explain what UM coverage is and state that limits will match bodily injury liability limits unless you request otherwise. Its heading must appear in 12-point bold type and warn that you are giving up valuable coverage.¹

Once a named insured signs, the law conclusively presumes an informed decision on behalf of everyone insured under the policy. One signature binds the whole household. Choosing non-stacked coverage requires a separate approved form explaining the limitations that come with non-stacking, and it works the same way: one named insured’s signature is treated as an informed, knowing acceptance for everyone on the policy.

If the insurer cannot produce a properly signed form, the coverage defaults back to full stacked UM at the bodily injury liability limits, regardless of what the declarations page shows or what premium was charged.

Settling With an Underinsured Driver: the 30-Day Notice

Before you sign a release with an at-fault driver’s liability insurer for a settlement that will not fully cover your damages, you have to notify every UM insurer that covers you. The notice must go by certified or registered mail. Your UM insurer then has 30 days to respond.²

Within that window, the UM insurer can authorize the settlement, in which case you sign the release and pursue your UM claim separately. If the UM insurer wants to preserve its own right to go after the at-fault driver, it must pay you the amount of the liability settlement offer within the same 30 days. If it does nothing for 30 days, you are free to finalize the settlement without giving up your UM claim.

Signing a release with the liability insurer before doing this can wipe out your UM claim entirely. It is one of the most damaging mistakes an injured person can make, and it is easy to make without a lawyer walking you through the sequence.

Deadline to File a UM Lawsuit

You have five years to file a lawsuit for uninsured or underinsured motorist benefits in Florida. That is longer than the two-year deadline that now applies to general personal injury lawsuits after the 2023 change to Florida’s statute of limitations. The five-year UM deadline was not affected by that change. Even with the longer window, evidence fades and insurers get more room to dispute your injuries the longer you wait.

The Tort Threshold and Pain-and-Suffering Damages

Florida limits when you can recover non-economic damages such as pain and suffering after a car accident. Under Florida Statute 627.737, those damages are available only if your injuries include a permanent loss of an important bodily function, a permanent injury, significant and permanent scarring, or death.³

Because UM coverage pays only what you are “legally entitled to recover” from the uninsured driver, this threshold applies to the non-economic portion of your UM claim as well. Economic losses such as medical bills and lost income are recoverable regardless of the threshold.

What to Do After a Crash With an Uninsured Driver

A few steps protect your claim from day one:

Call law enforcement and get a written police report. It creates the official record of the crash and the other driver’s insurance status.
Photograph the vehicles, the scene, and any visible injuries. Get contact information from witnesses. If the other driver says they have no insurance, note it, but do not rely on their word.
Notify your own insurer quickly. Policies typically require prompt notice, and late notice can give the carrier grounds to deny the claim.
Get medical treatment and keep every record. UM claims turn on medical evidence more than any other kind of proof.

Read your policy’s dispute resolution clause early. Some Florida UM policies send disagreements to mandatory arbitration; others send them to court. Which forum you end up in depends on the language your insurer wrote, not on your preference after the fact.
