Your doctor flagged a condition that might affect driving. You split time between Michigan and Florida. Here's what happens to your auto insurance, your license, and your vehicle registration when a medical review is triggered in either state.
How Medical Reviews Work When You Have Licenses or Property in Two States
Your primary residence state controls your license. If Michigan is your legal domicile — where you vote, file taxes, and hold your driver's license — that's where any medical review is processed, even if your doctor is in Florida. Michigan's Driver Evaluation Unit handles reviews for Michigan license holders regardless of where the triggering diagnosis occurred.
Florida cannot revoke or restrict a Michigan license. But if you hold a Florida driver's license because you switched your domicile, Florida's Bureau of Driver Improvement processes reviews for Florida residents. The Commercial Driver's License Information System shares medical restriction data between states, so a review in one state becomes visible to the other.
Most snowbirds hold one license and register their vehicle in their domicile state. If that's you, the medical review follows your domicile state's process. If you switched domicile to Florida within the past 12 months and your Michigan doctor reported a condition, Michigan will forward the report to Florida — but only Florida can act on a Florida license.
What Triggers a Medical Review and Who Reports It
Physicians are mandatory reporters in both Michigan and Florida for specific conditions: uncontrolled seizures, severe vision loss, lapses of consciousness, advanced dementia, and conditions that impair reaction time or judgment. Michigan uses form DI-15. Florida uses HSMV 83045. Both states set a 10-day reporting window from diagnosis.
Your doctor reports to the state that issued your license, not the state where the appointment occurred. A Sarasota neurologist treating a Michigan resident reports to Michigan. A Traverse City cardiologist treating a Florida resident reports to Florida.
Family members can also file a medical review request in either state, though this is less common. The request must include specific observed incidents — dates, behaviors, near-miss events — not general concern about age.
The Medical Review Process in Michigan vs. Florida
Michigan's Driver Evaluation Unit sends a vision and medical examination request within 14 days of receiving a report. You have 30 days to complete the exam with a licensed physician and return form BDVR-54. If the physician clears you, no restriction is added. If the physician recommends restrictions — daylight only, local radius, no expressways — Michigan adds them to your license record. Failure to respond within 30 days results in automatic suspension.
Florida's process is similar but uses form HSMV 83045 and allows 45 days for completion. Florida also requires a vision specialist report if the triggering condition affects sight. Restrictions in Florida include similar categories: daylight driving, speed-restricted roads, geographic radius limits.
Both states allow you to request a re-evaluation after 6 months if your condition improves or stabilizes. Neither state automatically removes restrictions — you must file for re-evaluation and submit updated physician documentation.
How a Medical Review Affects Your Auto Insurance in Both States
Your carrier pulls your motor vehicle record at renewal and when you file a claim. A medical restriction appears on your MVR the same way a speeding ticket does. Carriers in both states see it.
If you have a restriction added in Michigan and you carry a policy that covers both your Michigan and Florida addresses, your carrier may raise your rate at the next renewal. Typical increases for daylight-only or radius restrictions range from 8% to 18% depending on the carrier and your overall risk profile. Some carriers non-renew drivers with medical restrictions in high-risk classifications.
If you carry separate policies in each state — one for your Michigan address, one for your Florida address — both carriers will see the restriction at their next MVR pull. This typically happens at renewal, not mid-term, unless you file a claim. Expect similar rate increases on both policies.
No carrier offers a discount for passing a medical review. Passing simply avoids the increase. The review itself may trigger a closer look at your overall profile, especially if you're over 75 or have had prior lapses in coverage.
Do You Need to Register Your Vehicle in Florida If a Medical Review Happens?
A medical review does not change your vehicle registration requirement. You register where you live more than six months per year — your domicile. If you're a Michigan resident who winters in Florida, you register in Michigan. If you moved your domicile to Florida, you register in Florida within 10 days of establishing residency.
Florida's 10-day rule applies when you accept employment, enroll children in school, file a Florida Declaration of Domicile, or register to vote in Florida. Spending winters in a Sarasota condo you own does not trigger registration unless you also move your legal domicile.
A medical restriction on your Michigan license does not force you to switch to Florida registration. Your license state and registration state should match your domicile. If they don't — if you hold a Florida license but register your car in Michigan — you create a mismatch that carriers flag during underwriting, and some will decline to write the policy.
How to Maintain Continuous Coverage When Splitting Time Between States
Most major carriers write policies that cover a primary residence and a secondary seasonal address. You list both addresses on the application. The policy uses your garaging address — where the vehicle is parked overnight most of the year — to set the base rate. That's usually your domicile state.
If you have a medical review and restrictions added, notify your carrier within 30 days. This is required under most policy contracts. Failing to disclose a restriction can void coverage if you're involved in a claim and the carrier discovers the undisclosed MVR change during investigation.
Some carriers allow you to shift your garaging address seasonally. You notify them when you drive to Florida in November and again when you return to Michigan in April. Your rate adjusts based on where the car is garaged each period. This works cleanly with carriers like State Farm, Allstate, and USAA. Others require a single garaging address for the full term and won't adjust mid-term.
If your carrier non-renews you due to a medical restriction, you'll move to a non-standard carrier. Non-standard carriers in both Michigan and Florida write policies for drivers with restrictions, but expect rates 40% to 90% higher than standard market. Progressive, Acceptance, and Dairyland write restricted-driver policies in both states.
What Happens If You're Denied a License Renewal in One State
If Michigan or Florida denies your license renewal following a medical review, your auto insurance policy cancels. All carriers require an active valid license. You have 30 days from the denial to appeal through the state's administrative hearing process.
During the appeal, you cannot legally drive. Some carriers will hold your policy in suspended status if you provide proof of an active appeal, but most will cancel at the denial date. If you win the appeal and your license is reinstated, you'll need to re-apply for insurance. Expect to pay a lapsed-coverage surcharge, typically 15% to 25%, for 6 months.
If the denial is upheld, you lose your license in your domicile state. CDLIS shares the revocation with all states. You cannot obtain a license in Florida if Michigan revoked yours for medical cause, and vice versa. At that point, your vehicle must be registered and insured under another household member's name, or you sell the vehicle.
