The Six-Month Question Your Carrier Won't Answer Directly
You spend November through April in Florida, May through October in Michigan. Your car is Michigan-registered, your policy is with a Michigan carrier that operates in Florida, and your agent assured you the policy covers both states. Then a neighbor mentions Florida's six-month registration rule, your adult daughter sends you an article about insurance residency, and suddenly you're not sure whether you're compliant in either state.
The confusion is structural, not incidental. Michigan requires no-fault personal injury protection on every registered vehicle. Florida made PIP optional in 2012 and lets drivers substitute bodily injury liability instead. When you're a Michigan resident spending half the year in Florida, the conflict between those two systems creates a coverage gap your Michigan carrier is incentivized to blur and Florida's DMV does not actively police until something goes wrong.

$50,000
Michigan requires $50,000 per person, $100,000 per accident bodily injury liability, and $10,000 property damage. These minimums are higher than Florida's $10,000 PIP and $10,000 property damage requirements, but the structures do not map onto each other.

What Michigan Registration Actually Requires
A Michigan-registered vehicle must carry a Michigan no-fault policy. That policy includes personal injury protection covering your medical expenses after an accident regardless of fault, up to the PIP limit you selected under Michigan's 2020 tiered PIP reform. The reform lets Michigan residents with qualifying health coverage opt out of unlimited PIP and select lower limits, but even the lowest tier is significantly more coverage than Florida requires.
Your Michigan no-fault policy travels with you to Florida. If you're in an accident while driving in Florida as a Michigan resident with Michigan plates, your Michigan PIP pays your medical bills first. The problem surfaces when Florida decides you are no longer a Michigan resident for insurance purposes.
Florida statute requires anyone who works in Florida or enrolls children in Florida public schools to register their vehicle in Florida within ten days. If you do neither, the next threshold is six consecutive months of physical presence in Florida. At that point Florida considers you a resident for registration purposes, and your Michigan registration becomes legally insufficient for the vehicle you're driving in Florida every day.
You cannot be a Michigan insurance resident and a Florida vehicle-registration resident simultaneously. One state's definition forces you to violate the other's requirement.
The No-Fault Structure Conflict
Michigan requires unlimited or tiered PIP, with medical benefits paid by your own insurer regardless of who caused the accident. Florida made PIP optional in 2012, replacing it with a bodily injury liability requirement for drivers who opt out. If you register your vehicle in Florida and cancel your Michigan policy to comply with Florida's residency rule, you lose Michigan no-fault PIP. If you return to Michigan in May and reinstate Michigan registration without continuous Michigan no-fault coverage, the Michigan Secretary of State treats that as a lapse, which can trigger registration suspension and reinstatement fees.
The gap is not hypothetical. A snowbird who registers in Florida, drops Michigan coverage, and then has an accident in Michigan during the summer faces a situation where neither state's policy structure expected them. Florida bodily injury liability does not substitute for Michigan no-fault PIP when you are driving in Michigan, because Michigan is a no-fault state that does not allow you to sue for medical expenses the way Florida does. Your Florida policy will not pay your Michigan medical bills the way your Michigan PIP would have.

What Carriers Actually Sell to Snowbirds
Most carriers writing in both Michigan and Florida will tell you the policy covers you in both states, and that is technically true under the policy's out-of-state coverage provision. What they do not clarify is that out-of-state coverage assumes you remain a resident of the state where the policy is issued. If Florida reclassifies you as a Florida resident for registration purposes, your Michigan carrier's out-of-state provision no longer applies because you are no longer out of state; you are a Florida resident driving with the wrong state's policy.
A small number of carriers write multi-state policies explicitly designed for snowbirds, with endorsements that maintain Michigan no-fault PIP even when the vehicle is registered in Florida. These policies cost more because the carrier is assuming Michigan-level no-fault liability for a vehicle that spends half the year in a state with lower minimum requirements. Most carriers do not offer this structure, and most agents do not bring it up unless you ask the six-month question directly.
Verified carriers writing in Michigan with standard or preferred tier market positions include State Farm, Progressive, GEICO, Nationwide, Auto-Owners, and Amica. Not all write snowbird-specific policies. State Farm and Progressive have dedicated snowbird programs in some regions; ask your agent whether the Michigan policy includes a Florida-residency endorsement that maintains PIP compliance when you register the vehicle in Florida.
Carriers Writing Michigan Auto Policies

Fifteen carriers confirmed writing auto policies in Michigan per state licensing records. Not all write Florida policies, and of those that do, fewer than five offer snowbird-specific endorsements that resolve the no-fault PIP conflict.

The Registration Decision and Its Consequences
If you spend exactly six months in each state, you face a forced choice. Register in Michigan and maintain Michigan no-fault, accepting that Florida technically requires you to register there after six months of presence. Register in Florida and lose Michigan no-fault PIP during the months you are in Michigan, unless your carrier writes a policy that maintains Michigan PIP on a Florida-registered vehicle.
The enforcement gap is real. Florida does not systematically track how many days Michigan plates have been parked at a given address, and Michigan does not track whether your vehicle spent six months in Florida. The risk surfaces during an accident, a traffic stop, or a claim. If you are in an accident in Florida with Michigan plates after living there for seven months, and the other driver's attorney argues you were a Florida resident driving without proper Florida registration, your liability exposure increases. If you file a PIP claim in Michigan after spending the prior six months in Florida with Michigan plates, your carrier can argue you were not a Michigan resident at the time of the accident and deny the claim.
The Path That Actually Works
The defensible structure is this: maintain your primary residence in Michigan, register your vehicle in Michigan, and carry a Michigan no-fault policy that explicitly covers you during temporary stays in Florida. Do not enroll in Florida public services, do not register to vote in Florida, do not file a Florida homestead exemption, and do not work in Florida. These actions trigger Florida residency, which forces Florida registration, which breaks Michigan no-fault compliance.
If you own property in Florida, own it as a second home, not a primary residence. Your driver's license, voter registration, and vehicle registration all stay Michigan. Your insurance policy is Michigan no-fault, issued by a carrier that writes in Florida and confirms the policy's out-of-state provision applies to your Florida stays. Ask your agent to document in writing that the Michigan PIP coverage applies to accidents occurring in Florida while you are a Michigan resident temporarily present there.
If your work situation or family situation requires you to register in Florida, ask your carrier whether they write a Michigan-PIP-retention endorsement on a Florida-registered vehicle. If they do not, you will need to choose: either return to Michigan before the six-month threshold every year, or accept that you will lose Michigan no-fault PIP and rely on Florida bodily injury liability during the months you are in Michigan. That choice exposes you to medical-expense risk in Michigan that Michigan no-fault was designed to eliminate.
Talk to Your Carrier Before November
Call your Michigan carrier now and ask three questions. Does the policy's out-of-state provision cover you in Florida for stays longer than 180 days if you remain a Michigan resident? If Florida reclassifies you as a resident and requires Florida registration, does your carrier offer an endorsement that maintains Michigan PIP on a Florida-registered vehicle? If not, which carrier in your area does? Most agents will need to escalate the second question to underwriting. Get the answer in writing before you leave for the season.
