What Is Uninsured Motorist Coverage in Florida, and Do You Need It?

Uninsured motorist (UM) coverage, often paired with underinsured motorist (UIM) coverage, is the part of your auto policy that pays for your injuries and losses when the at-fault driver has no insurance at all, or doesn’t carry enough to cover what you’re owed. In Florida, UM/UIM coverage is optional, not mandatory. Insurance companies are required by law to offer it on every policy, and you have to reject it in writing on a state-approved form if you don’t want it.

That distinction matters more in Florida than in most states. Florida is one of the few states that doesn’t require drivers to carry bodily injury liability insurance, and multiple industry studies have put Florida among the states with the highest shares of uninsured and underinsured drivers in the country. Without UM/UIM coverage of your own, a crash caused by one of those drivers can leave you covering your own medical bills and lost wages out of pocket.

How Uninsured and Underinsured Motorist Coverage Works in Florida

UM and UIM coverage are usually bundled together on a single policy endorsement, but they cover two different situations. UM coverage steps in when the at-fault driver has no liability insurance whatsoever. UIM coverage steps in when the at-fault driver has some insurance, but their policy limits aren’t enough to pay for your medical bills, lost income, and pain and suffering.

Either way, the coverage works like a stand-in for the at-fault driver’s missing or insufficient insurance. You file the claim with your own insurance company, and your insurer pays out up to your UM/UIM policy limits, as if it were the at-fault driver’s insurer.

What Counts as “Uninsured” or “Underinsured” in Florida

Florida law and most policies treat several scenarios as triggering UM/UIM coverage:

• The at-fault driver has no bodily injury liability insurance at all.
• The at-fault driver has liability coverage, but the limits are too low to cover your damages.
• The at-fault driver fled the scene and can’t be identified, as in many hit-and-run accidents.
• The at-fault driver’s insurer denies coverage or becomes insolvent after the crash.

Why UM/UIM Coverage Is Optional in Florida (And Why That’s a Problem)

Florida’s mandatory minimum insurance requirements are narrower than most drivers realize. Every registered vehicle owner must carry at least $10,000 in Florida PIP insurance (Personal Injury Protection) and $10,000 in Property Damage Liability coverage. Bodily injury liability coverage, the kind that pays for another person’s injuries when you cause a crash, is not required for most private passenger vehicles. That’s a major reason UM/UIM coverage exists: a large number of Florida drivers are legally allowed to be on the road without any coverage for the injuries they cause to someone else.

Under Florida Statute 627.727, an insurer that sells bodily injury liability coverage must also offer UM coverage equal to those same bodily injury limits. If you want to reject UM coverage or choose lower limits, you have to do it in writing, on a form approved by the state, signed by the named insured. If the insurer can’t produce a valid, properly signed rejection form, Florida courts have held that UM coverage is reinstated by operation of law, at the same level as your bodily injury liability limits.

In practice, that means two things worth checking on your own policy: whether you actually have UM/UIM coverage, and if you rejected it at some point, whether you remember doing so and understood what you were giving up. Many drivers sign a rejection form years ago during a routine renewal and don’t realize the consequences until after a serious crash.

What Florida’s Mandatory Coverage Does and Doesn’t Pay For

It helps to see where PIP and property damage liability stop, and where UM/UIM is meant to pick up the slack.

Personal Injury Protection (PIP)

Your own $10,000 in PIP coverage pays a portion of your medical bills and lost wages after a crash, regardless of who caused it. But PIP has real limits: it typically covers only 80% of medical expenses and 60% of lost wages, up to the $10,000 cap, and it doesn’t compensate you for pain, suffering, or the full scope of a serious injury.

Property Damage Liability

The $10,000 in property damage liability a driver carries covers damage they cause to your vehicle or other property. It says nothing about your injuries.

The Gap UM/UIM Fills

Once your PIP benefits run out, and if the at-fault driver has no bodily injury liability coverage (or not enough), there’s no other source to pay for your pain and suffering, your remaining medical bills, or lost future income, unless you have UM/UIM coverage of your own.

Stacked vs. Non-Stacked UM Coverage

If you insure more than one vehicle on a policy, or have multiple policies in your household, Florida allows you to “stack” UM coverage, combining the per-vehicle limits into one larger available amount for a single claim. Stacked coverage costs more in premium, but it can make a significant difference after a catastrophic injury, where a single policy’s limits might not come close to covering the loss. Non-stacked coverage caps your UM benefit at a single vehicle’s limit, no matter how many vehicles you insure.

When UM/UIM Coverage Typically Comes Into Play

Some of the most common situations where UM/UIM claims arise include:

• A hit-and-run crash where the at-fault driver can’t be identified or located.
• A crash caused by a driver who was pulled over for no insurance at the scene.
• A crash with serious injuries where the at-fault driver’s bodily injury limits are far lower than the medical bills involved.
• Motorcycle crashes, where riders face a particularly high risk from uninsured drivers; it’s worth reviewing how motorcycle insurance in Florida handles UM coverage specifically, since riders often need it even more than passenger vehicle owners.

What to Do If You’re Hit by an Uninsured or Underinsured Driver

The steps you take right after the crash can affect whether a UM/UIM claim goes smoothly later:

1. Call the police and get a report. An official crash report documenting that the other driver had no insurance, or fled the scene, is key evidence for a UM/UIM claim.
2. Get medical care promptly. This protects your health and creates the medical documentation an insurer will expect. For a full breakdown of the right sequence of steps, see our guide on what to do after a car accident in Florida.
3. Notify your own insurer promptly. Most policies require timely notice of a potential UM/UIM claim, and delays can complicate the process.
4. Keep records of everything. Medical bills, lost wages, repair estimates, and correspondence with any insurer all matter.
5. Be careful what you sign or say. Statements to insurance adjusters, including your own, can be used to minimize a claim.

Filing a UM/UIM Claim: What to Expect

A UM/UIM claim is filed against your own insurance company, but that doesn’t make it simple. Your insurer still has a financial incentive to pay as little as possible, even though you’re a paying policyholder. Florida law requires insurers to handle UM/UIM claims in good faith, but disputes over the value of a claim, or over how severe an injury really is, are common.

Because a UM/UIM claim essentially asks your own insurer to evaluate a case the way a liability insurer would, having thorough documentation, a clear medical record, and, in many cases, legal representation can make a meaningful difference in the outcome. An attorney who regularly deals with Florida UM/UIM claims understands how insurers evaluate these cases internally and what it takes to support a fair settlement or pursue arbitration or litigation if a fair offer isn’t on the table.

Frequently Asked Questions

Is uninsured motorist coverage required in Florida?

No. Unlike PIP and property damage liability, UM/UIM coverage is optional in Florida. Insurers must offer it alongside bodily injury liability coverage, but you can reject it in writing on an approved form. If there’s no valid rejection on file, the law treats UM coverage as being in place at your bodily injury liability limits.

What’s the difference between uninsured and underinsured motorist coverage?

Uninsured motorist (UM) coverage applies when the at-fault driver has no liability insurance at all. Underinsured motorist (UIM) coverage applies when the at-fault driver has insurance, but the limits are too low to cover your damages. The two are typically combined into one UM/UIM policy endorsement.

Does uninsured motorist coverage apply to hit-and-run accidents in Florida?

Generally, yes. When the at-fault driver can’t be identified because they fled the scene, UM coverage typically treats the situation the same as a crash with an uninsured driver, provided the claim is reported and documented properly.

How do I know if I already have UM/UIM coverage on my policy?

Check your declarations page, or ask your insurance agent directly, for a line showing “Uninsured/Underinsured Motorist” coverage and limits. If you don’t see it listed, you may have signed a written rejection when you purchased or renewed the policy. Reviewing this before a crash happens, not after, gives you the clearest picture of your protection.

Sorting out UM/UIM coverage, especially after a serious crash with an uninsured or hit-and-run driver, often means going head-to-head with an insurance company over how much your claim is really worth.
