Florida Uninsured Motorist Coverage: UM, UIM, Hit-and-Run, and Next Steps
Florida uninsured motorist coverage can become important when the person who caused a crash has no bodily-injury liability insurance, does not have enough of it, leaves the scene, or another coverage problem prevents the available liability insurance from matching the injury loss.
This hub explains what UM and UIM are designed to address, how Florida policy selections can change the available coverage, what documents to check, how hit-and-run and underinsured claims fit in, and why settlement timing can matter.
General educational information only. Coverage depends on the policy, insured status, vehicles involved, accident facts, injuries, selections or rejections, and applicable Florida law.
Start with the policy record, not the label.
- Declarations pages for every potentially relevant auto policy.
- The UM/UIM selection or rejection form, if one exists.
- Policy endorsements showing stacked or nonstacked UM terms.
- The at-fault driver’s bodily-injury liability limits.
- Your claim numbers, denial or reservation letters, settlement offers, and releases.
- Household policies and the vehicle you occupied—or whether you were a pedestrian or bicyclist.
Quick answer
What does Florida uninsured motorist coverage do?
UM/UIM is generally bodily-injury coverage for an insured person who is legally entitled to recover damages from an uninsured or underinsured motorist. Florida’s consumer guidance describes UM as protection when the at-fault party has no bodily-injury liability coverage or does not have enough liability limits to cover the injury loss.
UM is not the same thing as PIP, collision, property-damage liability, or health insurance. PIP can address certain medical and wage-loss benefits regardless of fault; collision can address damage to an insured vehicle; UM/UIM focuses on qualifying bodily-injury damages connected to an uninsured or underinsured motorist.
Do not assume the policy has UM simply because it is a Florida auto policy. Section 627.727 generally requires UM to be provided with a policy that has bodily-injury liability coverage unless the named insured rejects UM in writing, and the statute also allows lower UM limits to be selected in specified circumstances.
Three questions come first
- Is the other driver uninsured, underinsured, unidentified, or affected by another liability-coverage problem?
- Which policy or policies may insure the injured person?
- What UM limits, rejection, lower-limit selection, or nonstacked limitation actually appear in the policy record?
What UM is — and is not
UM fills a bodily-injury insurance gap; it does not replace every other accident coverage.
UM / UIM
Addresses qualifying bodily-injury damages when the responsible motorist has no BI coverage, insufficient BI limits, or another situation treated as uninsured under the statute and policy.
PIP
Florida PIP can pay specified medical and wage-loss benefits without first deciding fault, subject to the statute, policy, treatment timing, benefit limits, and insured status.
Collision / property coverage
Vehicle repair or total-loss questions are generally handled through collision, property-damage liability, or another applicable property coverage—not through Florida UM bodily-injury coverage.
Policy check
Read the declarations page together with the UM selection or rejection record.
A declarations page may show a UM limit, but it may not answer every coverage question. The policy can also contain endorsements, named-insured definitions, resident-relative provisions, owned-vehicle limitations, exclusions, and a stacked or nonstacked UM selection.
Ask for the complete policy in force on the crash date, not only an insurance card. If the insurer says UM was rejected or lower limits were selected, ask for the applicable signed selection or rejection form and the declarations pages for the relevant policy term.
Also identify every potentially relevant household auto policy. UM analysis can depend on who is the named insured, who lives in the household, which vehicle was involved, whether the injured person was occupying a vehicle, and what selections were made.
Save these documents
- Declarations pages from the crash-date policy term.
- UM/UIM selection or rejection forms.
- Stacked or nonstacked endorsements.
- Policy definitions and coverage forms.
- Household policy declarations.
- The other driver’s BI declarations or limits disclosure, if available.
- Coverage-position, denial, or reservation-of-rights letters.
Uninsured vs underinsured
The other driver can be “underinsured” even when an insurance policy exists.
Section 627.727 treats certain insured vehicles as uninsured for UM purposes when the responsible driver’s bodily-injury limits are less than the total damages sustained by the person legally entitled to recover. That is the core underinsured-motorist problem: there is liability insurance, but the available BI limit may not be enough.
The statute also addresses other situations, including insurer insolvency and specified exclusions involving a nonfamily member operating an insured vehicle. The exact classification still depends on the statute, policy language, and facts.
Do not compare only medical bills with the BI limit. A final injury analysis can involve medical expenses, wage loss, future effects, permanency questions, and other legally recoverable damages. Conversely, the existence of a low BI limit does not automatically establish the amount recoverable under UM.
Do not confuse these numbers
- The at-fault driver’s BI limit.
- Your UM/UIM limit.
- Any stacked or nonstacked limitation.
- PIP or medical-pay benefits.
- Health-insurance payments or reimbursement claims.
- The actual damages that can be proved under the applicable law.
Stacked and nonstacked UM
Do not calculate available UM from the number of vehicles alone.
Florida law permits insurers to offer UM with specified limitations often described as nonstacked coverage. Section 627.727 sets rules that can change which UM limit is available depending on whether the injured person was occupying a vehicle, who owned it, and whether the injured person was a named insured or insured resident family member.
That means “three cars on the policy times the UM limit” is not a safe assumption, and neither is “only the car in the crash matters.” The answer depends on the actual UM selection, policy form, household status, and accident setting.
If an insurer relies on a nonstacked limitation, obtain the declarations, endorsement, and signed selection form that apply to the crash-date policy term. Do not rely on a renewal invoice or verbal description alone.
Questions to ask the insurer
- Is the UM coverage stacked or nonstacked?
- What document shows that selection?
- Which policy definition makes this person an insured?
- Which vehicle or household fact is being used to determine the limit?
- Is the insurer asserting an exclusion or owned-vehicle limitation?
- What exact UM limit does the insurer say is available, and why?
Hit-and-run and unidentified drivers
A hit-and-run can create a UM question, but coverage should not be assumed from the label alone.
When the responsible driver cannot be identified or no liability insurance can be confirmed, notify the appropriate insurer promptly and preserve the evidence that connects the unknown vehicle to the crash. Policy notice requirements and proof issues can become important.
Save partial plate information, vehicle description, witnesses, police records, camera footage, debris, paint transfer, damage patterns, and the direction the vehicle left. Do not chase the vehicle or delay medical care in order to investigate.
Preserve before the trail goes cold
- 911 and law-enforcement information.
- Witness names and contact details.
- Dashcam, helmet-camera, traffic, business, or doorbell video.
- Photos of impact damage, debris, paint transfer, and the scene.
- Your own UM/UIM policy documents and claim notice.
Who may be covered
UM can depend on the person, household, vehicle, and whether anyone was occupying a motor vehicle.
Do not assume UM belongs only to the driver of the insured car. Section 627.727 expressly addresses circumstances where an injured insured is not occupying a motor vehicle.
Driver or passenger
Coverage can depend on the vehicle occupied, ownership, policy definitions, household status, and stacked or nonstacked terms.
Pedestrian
An insured person struck while not occupying a motor vehicle can raise UM questions under the policy and the statutory rules governing the available limit.
Bicyclist
A bicyclist struck by a motor vehicle may need to check household auto policies and UM status in addition to PIP, liability, health insurance, and bicycle-property issues.
Motorcyclist
Motorcycle ownership, policy structure, occupied-vehicle rules, and household coverage can make UM analysis different from a conventional passenger-car crash.
Rideshare or commercial setting
Personal, platform, commercial, employer, vehicle-owner, and household policies can interact. Do not assume that a personal-policy answer automatically controls the rideshare or commercial layer.
Resident family member
The policy’s named-insured and resident-relative definitions can matter even when that person was not driving the listed vehicle. Household facts should be documented rather than assumed.
Settlement timing
Before releasing an underinsured driver, check whether the UM insurer must be notified.
Section 627.727 contains a specific process for certain underinsured-motorist situations when an injured person agrees to settle with the liability insurer and its insured for less than the full injury claim. The statute calls for written notice of the proposed settlement to the UM insurer and provides a 30-day period for the UM insurer to consider authorization or preservation of subrogation rights.
This is not a reason to calculate a deadline from this page. It is a warning not to sign a release with the underinsured driver or liability insurer without checking whether the statutory and policy notice process applies to the claim.
If the UM insurer refuses permission in order to preserve subrogation rights, the statute describes a payment mechanism tied to the liability insurer’s written offer. The exact procedure should be matched to the documents and current claim posture.
Before accepting the BI settlement
- Confirm the at-fault driver’s BI limits.
- Confirm every potentially applicable UM/UIM policy.
- Save the written liability settlement offer.
- Ask whether the UM carrier requires or has received written notice.
- Do not assume a general release preserves the UM claim.
- Keep every authorization, response, and date.
Warning signs
UM questions deserve closer attention when the coverage picture or injury picture is not settled.
The other driver has no BI or very low BI limits
The liability coverage may not match the injury loss, making UM/UIM policy review important before the claim is resolved.
The UM carrier says coverage was rejected
Ask for the applicable signed rejection or lower-limit selection and the crash-date declarations rather than accepting a verbal summary.
Several household or vehicle policies may matter
Named-insured status, resident-relative definitions, ownership, occupancy, and stacked/nonstacked selections can change the analysis.
The driver fled or cannot be identified
Evidence and policy-notice questions can become more important because there may be no ordinary liability insurer to handle the bodily-injury claim.
A liability settlement and release are ready
The UM/UIM notice and subrogation process may need to be checked before the underinsured driver is released.
Injuries are serious or still developing
It may be too early to know whether the at-fault BI limit is sufficient or what loss the UM claim may need to address.
Choose your current stage
Use the guide that matches the insurance problem you have now.
The insurer just called
Identify the company, claim number, coverage role, what it wants, and whether the request is recorded or written.
Medical bills are building
Keep PIP, health insurance, providers, denials, unpaid balances, and reimbursement questions separate from the UM limit itself.
The driver left the scene
Preserve identification evidence, notify law enforcement and insurers, and organize your own coverage record.
Fault is disputed
UM does not eliminate the need to establish legal responsibility and damages. Preserve the evidence before accepting a fault percentage.
A settlement or release is ready
Check the BI settlement scope, unresolved damages, reimbursement issues, and any UM notice process before signing or releasing the driver.
A deadline or legal paper appeared
Do not let insurance negotiations replace a stated response, filing, appearance, or other formal date.
Legal help
When individual review may make sense in a Florida UM/UIM claim.
Not every UM question requires a lawyer. A clear policy, modest injury, accepted coverage position, and straightforward claim may remain manageable through careful document review and insurer communication.
Individual legal review may be useful when injuries are serious or changing, the insurer disputes insured status, says UM was rejected, applies a nonstacked or owned-vehicle limitation, denies coverage, several household policies may apply, a hit-and-run or unidentified vehicle creates proof issues, the BI settlement may trigger a UM notice process, damages may exceed available limits, or formal legal deadlines are involved.

FAQ
Common Florida uninsured motorist questions.
Is uninsured motorist coverage required in Florida?
Not every Florida auto policy will have UM. Under section 627.727, a motor-vehicle liability policy with bodily-injury liability coverage generally includes UM unless the named insured rejects it in writing, and the statute permits lower UM limits to be selected in specified circumstances. Check the actual policy and selection or rejection form.
What is the difference between UM and UIM?
UM commonly refers to an at-fault motorist without applicable bodily-injury liability coverage. UIM refers to a motorist whose BI limits are insufficient compared with the total damages. Florida section 627.727 includes underinsured situations within the statutory UM framework.
Does UM pay for damage to my car?
Florida UM is bodily-injury coverage. Vehicle repair or total-loss questions are generally handled through collision, property-damage liability, or another applicable property coverage.
Can UM apply in a hit-and-run?
A hit-and-run can create a UM coverage question, especially when the responsible vehicle or liability coverage cannot be identified. The answer depends on the policy and proof of the crash, so notify the insurer and preserve the identifying evidence rather than assuming coverage.
Can a pedestrian or bicyclist use UM coverage?
Potentially, depending on insured status and policy terms. Section 627.727 expressly addresses an injured insured who is not occupying a motor vehicle, and household-policy questions can therefore matter in pedestrian and bicycle crashes.
What does “nonstacked UM” mean?
Florida law permits UM policies with specified limitations often called nonstacked coverage. The available limit can depend on occupancy, vehicle ownership, household status, and the signed policy selection. Do not calculate the limit from the number of insured vehicles without reviewing the policy record.
What if the insurer says I rejected UM coverage?
Ask for the signed UM rejection or lower-limit selection form and the declarations from the policy term in force on the crash date. Do not rely only on a verbal explanation or current renewal page.
What if the other driver has insurance, but the limit is too low?
That is the classic underinsured-motorist question. Section 627.727 treats specified situations with BI limits below total damages as uninsured for purposes of UM coverage, subject to the statute, policy, and proof of damages.
Can I settle with the other driver before making a UIM claim?
Potentially, but section 627.727 contains a notice process for certain proposed underinsured settlements and gives the UM insurer a 30-day period to address authorization or subrogation. Check the actual claim before signing a release.
When should I consider legal help?
Individual review may be useful when coverage is denied or disputed, the insurer relies on a rejection or nonstacked limitation, several policies may apply, injuries are serious, a hit-and-run creates proof issues, available BI limits appear insufficient, or a liability settlement may affect UM rights.
