Key Takeaways

  • Stacked uninsured motorist coverage multiplies your per-person limit by the number of vehicles insured on your policy. Non-stacked coverage caps out at a single limit regardless of vehicle count.
  • Stacked coverage is the default under Florida Statute 627.727. To get non-stacked coverage, you must sign a specific selection form acknowledging the limitation.
  • Insurers must offer at least a 20% premium discount on the UM portion of your bill for choosing non-stacked coverage, a savings that only applies to that line item, not your whole car insurance policy.
  • Two vehicles insured at $50,000 in UM coverage each becomes up to $100,000 available under stacked coverage, but stays capped at $50,000 total under non-stacked coverage.
  • Stacked UM coverage also extends beyond your own car: it follows you as a pedestrian, a cyclist, and a passenger in someone else’s vehicle, while non-stacked coverage offers narrower protection.

Two Florida drivers can carry the exact same UM coverage limit on paper and end up with wildly different amounts of actual protection after a serious crash, depending on one box checked at signup. If you’re deciding between stacked and non-stacked uninsured motorist coverage, the practical answer for most households with more than one vehicle is that stacked coverage is worth the extra cost, and a meaningful number of Florida drivers have unknowingly opted out of it without realizing what they gave up.

Uninsured motorist coverage under auto insurance in Florida is governed by Florida Statute 627.727, and it comes in two forms that Florida law treats very differently. Stacked coverage multiplies your UM limit by the number of vehicles you insure on the policy. Non-stacked coverage gives you a single limit no matter how many cars are on the policy. Below is a step-by-step walkthrough for figuring out which one you have, which one you need, and how to switch if needed.

How to choose between stacked and non-stacked UM coverage in Florida

Step 1: Check your declarations page to see what you currently have

Before deciding anything, find out what you’re actually carrying today. Pull up your declarations page and look for a line that reads “stacked” or “non-stacked” next to your uninsured motorist coverage. If you can’t find it, call your agent or insurer and ask directly. Since stacked coverage is the default under Florida law, you likely have it unless you specifically signed a non-stacking election form, but it’s worth confirming rather than assuming.

Step 2: Count your vehicles and household drivers

Stacking only matters if there’s something to stack. Count how many vehicles are listed on your policy and how many resident relatives or household drivers are covered under it. A single driver with one car sees little practical difference between stacked and non-stacked UM. A household with two, three, or more insured vehicles has real money on the table, since each additional vehicle on a stacked policy adds another full UM limit to your available protection.

Step 3: Get a quote for both stacked and non-stacked UM from your carrier

Ask your insurer or agent for two side-by-side quotes on the same policy, one with stacked UM and one with non-stacked UM, at the same coverage limit. Insurers vary in how they price the 20% minimum discount beyond that floor, so the only way to know your actual number is to ask for both quotes directly.

Step 4: Compare the real dollar difference, not just the percentage

Once you have both quotes, look at the actual dollar gap, not the advertised discount. Because the non-stacked discount applies only to the UM line item and not your full car insurance policy, the total savings is often a fairly small number, sometimes under $100 a year. Weigh that modest savings against the coverage gap: for two vehicles at $50,000 in UM each, going non-stacked can mean giving up $50,000 in potential protection to save a fraction of that amount annually.

Step 5: Make your election in writing and confirm it on your next renewal

If you decide non-stacked coverage makes sense for your situation, your insurer will have you sign a specific selection form; Florida law requires this in writing, and a signature is what actually changes your coverage from the stacked default. If you decide to keep or switch back to stacked coverage, confirm that with your agent as well. Either way, revisit this decision at each renewal, particularly if you’ve added a vehicle or a new driver to the household.

Is stacked or non-stacked UM coverage the default in Florida?

Stacked coverage is the default. Florida law requires insurers to offer UM coverage in an amount matching your bodily injury liability insurance limits, and unless you specifically sign a form electing non-stacked coverage, the policy is supposed to include stacking. Florida courts have generally sided with policyholders when an insurer can’t produce a signed election form, treating the coverage as stacked by default.

How much cheaper is non-stacked coverage?

Florida law requires insurers to give policyholders at least a 20% premium reduction for choosing non-stacked coverage, though that discount applies only to the UM portion of your bill, not your entire insurance coverage. For a household insuring two or three vehicles, the potential coverage lost by going non-stacked frequently outweighs the modest premium savings.

What happens if you’re hit by an uninsured or underinsured driver in Florida?

Your PIP coverage pays medical expenses and lost wages first, up to $10,000, regardless of fault. But PIP doesn’t cover vehicle damage, and it caps out well below what a serious injury can cost. If the at-fault driver has no bodily injury liability insurance, or not enough of it, there’s no adequate policy on their end to pursue. Uninsured motorist coverage and underinsured motorist coverage are what fill that gap, paying for medical bills, lost wages, and pain and suffering beyond what PIP covers after a car accident. Whether you have $50,000 or $150,000 available to draw from in that moment often comes down to whether your policy is stacked or not.

What does uninsured motorist coverage not cover?

UM and UIM coverage fill a specific gap, and it’s worth knowing where that gap ends. UM coverage does not pay for damage to your own vehicle, that falls under collision coverage instead, and it does not pay for injuries or property damage you cause to someone else, which is what bodily injury liability insurance and property damage liability cover on your own policy. It also doesn’t apply if you were found at fault for the accident.

Florida law also limits UM claims after a hit-and-run. Unless there’s physical contact between vehicles or other corroborating evidence, an insurer can deny a hit-and-run UM claim. And no matter how severe the injuries or how high your medical bills climb, UM and UIM payouts never exceed the coverage limit you selected. A driver carrying $25,000 in UM coverage won’t recover more than that from their own insurer, even if a jury would have awarded far more in a lawsuit against the at-fault driver directly.

Does stacked coverage apply outside your own car?

Yes, and this is one of the more overlooked advantages of stacking. Stacked UM coverage follows you as a pedestrian, a cyclist, and a passenger in someone else’s vehicle, not just while you’re driving your own insured car, and it responds the same way whether a car accident involves an uninsured or underinsured motorist. Non-stacked coverage offers narrower protection in these scenarios. For households with a motorcycle rider or anyone who frequently rides as a passenger, this distinction carries extra weight, since a single-vehicle non-stacked policy may leave those situations thinly covered.

Can you stack coverage across multiple insurance policies, not just multiple vehicles?

Stacking within a single policy, combining UM limits across multiple vehicles you insure with one carrier, is the scenario most Florida drivers think of. But Florida Statute 627.727 also addresses a less common situation: stacking across separate insurance policies. If you or a resident relative are covered under more than one auto insurance policy, Florida law has historically allowed stacking those policies together under certain conditions, subject to any valid anti-stacking language the insurer included.

This area gets legally complicated quickly. Insurers sometimes write anti-stacking provisions into policies to prevent combining limits across separate policies, and Florida courts have upheld some of those provisions while striking down others depending on the exact policy language and the relationship between the insured parties. If your household has more than one auto insurance policy, talking to your insurer directly, or a Florida attorney familiar with UM stacking disputes, is worth the time.

How do Florida’s top insurers price stacked UM coverage?

Most carriers don’t advertise a separate price for non-stacked UM, since the stacked-versus-non-stacked choice is typically presented as an election at the point of sale rather than two separately marketed products. What is publicly comparable across carriers is the full-coverage rate that already includes Florida’s most common stacked uninsured motorist coverage limit, $100,000 per person and $300,000 per accident. The table below gives you a stacked-coverage baseline to compare against when you ask each carrier to quote the non-stacked savings directly, the same comparison described in Step 3 above. The uninsured motorist coverage limit you choose has a direct effect on your car insurance policy’s overall price, not just the UM line item.

CarrierAvg. monthly rate, full coverage (includes $100,000/$300,000 stacked UM)Notes for stacking shoppers
State FarmApproximately $175Ties for the lowest full-coverage rate in this dataset; local agents can quote the non-stacked election alongside the stacked baseline
GEICOApproximately $175Also among the cheapest; sold direct online, so confirm the stacking election explicitly during checkout
TravelersApproximately $197Frequently ranked among the cheapest full-coverage carriers in Florida across multiple rate surveys
NationwideApproximately $253Mid-range pricing among major carriers writing in Florida
ProgressiveApproximately $442Rates vary sharply by driver profile; ask specifically for both stacked and non-stacked UM quotes side by side

Sample rates only; these reflect full-coverage quotes for a 35-year-old driver with a clean record, drawn from a single rate survey for consistency, and assume stacked UM is included by default. Actual non-stacked savings depend on your carrier, UM limit, and number of insured vehicles, but Florida law sets a 20% minimum discount on the UM line item.

The bottom line

Stacked versus non-stacked uninsured motorist coverage is one of the more consequential, and least understood, choices on a Florida auto policy. The discount for going non-stacked sounds appealing, but it applies to a narrow slice of your bill while potentially cutting your available coverage by half or more just when medical bills from a serious claim start piling up. Walking through the five steps above turns an easily overlooked policy detail into a deliberate choice.

Before your next renewal, ask your agent directly which form you have and get quotes for both stacked and non-stacked coverage across at least three carriers. Given Florida’s uninsured driver rate, this is one line item worth spending a few extra minutes on.

Frequently asked questions

What is the difference between stacked and non-stacked UM coverage in Florida?

Stacked coverage multiplies your uninsured motorist limit by the number of vehicles on your policy, while non-stacked coverage caps your total available limit at a single amount regardless of how many vehicles you insure.

Is stacked UM coverage the default in Florida?

Yes. Florida law defaults to stacked coverage unless you sign a specific form electing non-stacked coverage. Without a signed election form, insurers are generally required to provide stacked coverage.

How much does non-stacked coverage save on car insurance premiums?

Insurers must offer at least a 20% discount on the UM portion of your premium for choosing non-stacked coverage, though that discount applies only to that specific line item, not your entire policy.

Do I need stacked coverage if I only have one car?

Stacking has less impact with a single vehicle since there’s nothing to multiply, though stacked coverage’s broader protection as a pedestrian, cyclist, or passenger in another vehicle can still apply.

What happens if I’m hit by an uninsured driver without UM coverage?

Your PIP coverage pays medical bills and lost wages up to $10,000, but you have no additional recourse for costs beyond that limit or for vehicle damage without collision coverage, since there’s no liability policy on the at-fault driver’s side to pursue.

Does stacked coverage apply to underinsured motorist coverage too?

Yes. Florida treats uninsured and underinsured motorist coverage under the same statute, so the stacking rules apply the same way whether the at-fault driver in your car accident had no insurance coverage at all or simply didn’t carry enough.

How do I actually switch from stacked to non-stacked UM coverage, or the other way around?

Contact your agent or insurer directly and request the change. Switching to non-stacked requires signing a specific election form, since Florida law requires that in writing; switching back to stacked typically just requires notifying your insurer, since stacked is the statutory default once no non-stacking election is on file.
