When a Doctor Says It's Time: Montana's Medical Referral System

Montana offers two restricted license categories that can preserve your ability to drive legally while under medical review: daylight-only restrictions and radius restrictions. A daylight restriction limits driving to one hour after sunrise to one hour before sunset. A radius restriction confines driving to a specific geographic area, typically a 25-mile or 50-mile radius from your residence, and may include specific approved routes to medical appointments or essential services. You must request the restriction during your response to the MVD review notice. If you wait until after a full suspension is issued, the process resets and requires full medical clearance before any license is reinstated. The restriction request requires a supporting letter from your physician stating that the condition is managed, the restriction addresses the specific impairment, and the doctor believes you can drive safely within those limits. Restricted licenses remain valid as long as the medical condition remains stable and you comply with the restriction terms. Violating the restriction — driving at night under a daylight restriction or outside your approved radius — results in immediate suspension and potential misdemeanor charges. Your insurance carrier receives notification of the restriction and must file it with your policy, but the restriction itself does not automatically trigger a rate increase if no violation or accident occurs.

Most carriers will continue coverage during an MVD medical review as long as your license remains valid or restricted, not suspended. The critical distinction is that a restricted license is still a valid license under Montana law — you are legally permitted to drive within the stated limits. Suspension, even temporary suspension pending clearance, typically triggers a policy lapse or non-renewal depending on how long the suspension remains unresolved. Carriers vary in how they handle restricted licenses at renewal. Some apply no rating change if the restriction is medical rather than violation-based and your record shows no accidents or claims during the restriction period. Others move you into a higher-risk tier, particularly if the restriction involves progressive conditions like dementia or uncontrolled seizure disorders. Expect the question about license restrictions to appear on your renewal application — answering inaccurately is grounds for claim denial. If your license moves from restricted to fully suspended, most standard carriers will non-renew at the next renewal period. Montana does not operate an assigned risk pool for medically suspended drivers the way it does for violation-based suspensions, which means your options narrow to non-standard carriers willing to write policies for drivers with suspended licenses or waiting until full reinstatement. Reinstatement after medical suspension requires submitting updated medical clearance from your physician and passing a knowledge test and road test administered by the MVD.

If you are the adult child or family member of a senior driver who received an MVD medical review notice, your first action is to contact the referring physician within the first week. Request a copy of the referral form submitted to the MVD and ask whether the doctor believes a restricted license is medically appropriate. If the physician supports a restriction rather than full suspension, request a written statement for the MVD response packet that explicitly recommends the restriction type and duration. The MVD response deadline is strict — 30 days from the notice date, not the date the letter was opened. Assemble the medical documentation, complete the driver questionnaire, and if pursuing a restricted license, include the restriction request form and physician support letter in a single submission. Mail it certified with return receipt so you have proof of timely filing. Before the review outcome is issued, contact your senior family member's insurance agent to confirm the carrier's policy on restricted licenses. Ask specifically whether a daylight or radius restriction affects the premium, whether it triggers a non-renewal review, and what documentation the carrier requires once the restriction is issued. Some carriers request a copy of the restricted license and updated MVD record. Having this information before the restriction is finalized lets you budget for potential rate changes and compare alternative carriers if non-renewal becomes likely.

If the MVD medical review results in full suspension and reinstatement is not immediately possible, Montana allows you to convert an active auto policy to a non-driver or storage policy that maintains continuous coverage without paying for liability you cannot legally use. This conversion prevents a coverage gap, which matters when you eventually reinstate your license and return to the standard market. A non-driver policy or storage policy retains comprehensive coverage for theft, vandalism, fire, and weather damage but drops liability and collision. Monthly premiums typically fall to $15–$35 per month depending on the vehicle value. You cannot drive the vehicle under this policy — doing so while suspended creates both criminal exposure and claim denial. The policy remains active and avoids the lapse that creates higher reinstatement quotes later. If reinstatement occurs within 12 months and you maintained continuous non-driver coverage during the suspension, most carriers will reinstate your full policy at the pre-suspension rate tier, though you may see an age-based increase if you crossed a rating threshold during the suspension period. If the suspension extends beyond 12 months or you allowed the policy to lapse entirely, expect to re-enter the market as a new applicant, which at age 75 and older often means higher quotes and fewer carrier options. Maintaining the storage policy preserves your status as a continuously insured driver, which is the single strongest rating factor working in your favor when reinstatement becomes possible.
