Florida Uninsured Motorist Statute: Coverage, Stacking, Deadlines

The Florida uninsured motorist statute, Section 627.727 of the Florida Statutes, requires every auto insurer that sells bodily injury liability coverage in the state to include uninsured motorist (UM) protection at matching limits unless the policyholder rejects it in writing on an approved form. The coverage pays when the driver who hit you carries no bodily injury insurance, carries too little to cover your damages, flees the scene, or has an insurance company that has gone insolvent. Given that roughly one in five Florida drivers has no bodily injury liability coverage at all, this statute quietly does more work than most policyholders realize until they file a claim.¹

What Insurers Must Offer and How You Can Reject

Whenever a Florida insurer issues a policy with bodily injury liability (BIL) limits, it must also provide UM coverage at those same limits. Carry $100,000/$300,000 in BIL, and you’re automatically entitled to $100,000/$300,000 in UM protection unless you affirmatively decline or select lower limits.²

You can reject UM coverage or pick lower limits, but only on a form approved by the Florida Office of Insurance Regulation. That form must carry a 12-point bold heading warning that you’re giving up valuable protection. Once you sign, the rejection binds every insured person under the policy and carries forward through renewals unless you later ask to add coverage back and pay the premium.²

Insurers must also send an annual reminder about your UM options with your premium statement, along with a way to request coverage. Receiving that notice, however, doesn’t count as a waiver. If your insurer can’t produce a valid signed rejection form, courts have found that UM coverage exists by operation of law at the full BIL limits.

What UM and UIM Coverage Pay For

UM coverage compensates you for medical bills, lost income, and pain and suffering when the at-fault driver has no bodily injury insurance. It fills a gap that Florida’s mandatory personal injury protection (PIP) can’t close on its own. PIP pays 80 percent of medical costs and 60 percent of lost wages up to $10,000 regardless of fault, but it doesn’t touch pain and suffering, and it runs out quickly in a serious crash.

Underinsured motorist (UIM) protection lives in the same statute. Under Section 627.727(3), a vehicle counts as “uninsured” when the at-fault driver’s liability limits are too low to cover your damages. If someone with $10,000 in BIL hits you and your injuries are worth $80,000, your own UIM coverage picks up the shortfall.²

Florida currently requires drivers to carry only PIP and property damage liability. Bodily injury liability is not mandatory, which is why so many drivers on Florida roads have none at all. The Insurance Research Council’s most recent data puts Florida’s uninsured motorist rate at 20.6 percent, seventh in the nation.¹ Legislative proposals to repeal PIP and require BIL have been introduced repeatedly but had not passed as of early 2026.

Hit-and-Run Drivers and Insolvent Insurers

The statute treats a hit-and-run driver as uninsured because there’s no identified policy to claim against. Florida policies typically require corroboration for phantom vehicle claims, such as physical contact with the unidentified vehicle or independent witness statements, to prevent fraud. Filing a police report immediately and gathering any available evidence strengthens your ability to trigger UM benefits.

UM coverage also protects you when the at-fault driver’s insurer goes broke. Under Section 627.727(4), that protection applies as long as the insurer becomes insolvent within four years of the accident. In that situation, the claim goes through the Florida Insurance Guaranty Association, which handles payments from insolvent carriers.²

Stacked and Non-Stacked Coverage

Stacking lets you combine UM limits across multiple vehicles on the same policy. Insure two cars at $50,000 in UM each, and stacked coverage gives you access to $100,000 in benefits after a single accident. Stacking is the default under Florida law. You get it unless you affirmatively accept a non-stacking alternative.

Under Section 627.727(8), insurers can offer non-stacked policies, but only with language approved by the Office of Insurance Regulation and only after informing you of what you’re giving up. Once you sign, the acceptance is presumed informed and binding, and it carries forward through renewals unless you request stacked coverage and pay the higher premium.³

Non-stacked coverage limits what you can collect depending on where you were when the accident happened:

In your own insured vehicle, you get the UM limit tied to that specific vehicle.
In someone else’s vehicle, you get the highest UM limit from any single vehicle on your policy, and that coverage is excess over the vehicle owner’s coverage.
As a pedestrian or cyclist, you can select the UM limit from any one vehicle on your policy.

Stacking costs more in premium because the insurer’s exposure is higher. Whether the extra cost makes sense depends on how many vehicles you own, how much you drive, and how strong your health coverage is.

Exclusions That Can Block a Claim

Even with UM coverage in place, certain situations can defeat a claim. The most consequential exclusion in non-stacked policies targets vehicles you own but didn’t insure under the policy. Under Section 627.727(8)(d), if you or a family member in your household is injured while riding in a vehicle you own but for which you didn’t purchase UM coverage, the policy won’t pay. This catches people who insure one car but not another, assuming their UM coverage follows them anywhere. Under a non-stacked policy, it doesn’t.²

Florida courts have also upheld the household vehicle exclusion, which denies UM benefits when the accident involves a vehicle covered under a different policy, even one from the same insurer. Some policies also exclude non-family passengers riding in the insured vehicle if they aren’t named on the policy. Rental cars and employer-provided vehicles create their own gaps: personal UM benefits may not apply unless your policy explicitly extends to non-owned vehicles. Check the policy language rather than assuming your coverage travels with you.

The Settlement Notice Rule That Kills UIM Claims

More UIM claims fall apart on this than on anything else in the statute. When the at-fault driver has some insurance but not enough, the natural move is to settle with their liability carrier and then pursue a UIM claim against your own insurer. Sign a release with the at-fault driver’s insurer without notifying your UIM carrier first, and you can destroy your own claim.

Section 627.727(6) requires you to send written notice of any proposed settlement to your UIM insurer by certified or registered mail before finalizing it. Your insurer then has 30 days to either authorize the settlement or preserve its subrogation rights by paying you the amount of the liability insurer’s offer itself. If your UIM insurer stays silent for 30 days, you can settle without prejudicing your UIM claim.³

Skip the notice, and your UIM insurer may argue that by releasing the at-fault driver, you eliminated its right to pursue that driver for reimbursement. Treat the 30-day notice as non-negotiable any time you’re settling with a liability insurer whose limits don’t fully cover your damages.

How Fault Affects What You Recover

To collect UM benefits, you must show you’re legally entitled to recover damages from the uninsured or underinsured driver. Fault still matters. Florida uses a modified comparative negligence system, and if you’re found more than 50 percent responsible for the accident, you cannot recover any damages at all.⁴

Below that threshold, your award gets reduced by your percentage of fault. Damages of $100,000 at 30 percent fault yield $70,000. Insurers routinely use this to push settlements down, so expect them to scrutinize the accident report and argue you share more blame than you think. Be careful about giving recorded statements before you understand how they’ll be used to assign fault percentages.

Deadline to File Suit

You have five years from the date of the accident to file a UM lawsuit in Florida. Florida shortened its general personal injury statute of limitations to two years in 2023, but that change applies to negligence claims against other drivers. A UM claim is a first-party contract claim against your own insurer, and the five-year limitations period for written contracts still applies. Waiting creates practical problems even when you have time on the clock. Witnesses move, medical records become harder to tie to the accident, and insurers gain leverage the longer the case sits.

When the Insurer Refuses to Pay Fairly

When your insurer denies a valid UM claim or offers far less than the damages justify, Florida Statutes Section 624.155 gives you a path to hold it accountable. The statute requires insurers to handle claims in good faith: fair investigation, reasonable response times, and real reasons for any denial or lowball offer. Mere negligence isn’t enough. The conduct must reflect deliberate or reckless disregard for your interests.⁵

Before suing for bad faith, you must file a civil remedy notice with the Florida Department of Financial Services on the department’s official form. The notice has to identify the statutory language the insurer violated, the facts behind the violation, the individuals involved, and any relevant policy language. Once filed, the insurer gets 60 days to pay the damages or correct the violation. If it does neither, you can proceed with a bad faith lawsuit.⁵

A successful bad faith claim can recover damages beyond your policy limits, along with attorney’s fees. The Florida Supreme Court established an important sequencing rule in Fridman v. Safeco Insurance Co. of Illinois: you must first get a jury to determine liability and the full extent of your damages in the underlying UM case before pursuing bad faith against the same insurer. That jury’s damages finding then binds the bad faith case, provided both sides had a chance to appeal any trial errors.⁶

If the dispute is over how much the claim is worth rather than bad faith, many UM policies include an arbitration clause. Arbitration resolves faster than litigation but typically limits your ability to recover extras like attorney’s fees. A straight breach of contract lawsuit remains an option when the insurer simply refuses to honor the policy terms.
