Seizure Disorder and Driving in NH: Medical Clearance & Insurance

New Hampshire law requires a minimum 6-month seizure-free period before the Division of Motor Vehicles will restore or issue a driver's license following a seizure disorder diagnosis. This waiting period applies to all drivers regardless of age and begins from the date of the last seizure, not from the date of diagnosis or treatment initiation. The 6-month standard applies to controlled seizure disorders where a physician certifies that the condition is managed through medication or other treatment. If seizures remain uncontrolled or occur while driving, the DMV may extend the waiting period or deny licensure entirely until a neurologist provides medical clearance. Drivers over 65 should note that the reinstatement process requires the same documentation as younger drivers—there is no separate senior driver pathway. During the waiting period, you cannot legally operate a vehicle in New Hampshire. If you drive before medical clearance and reinstatement, you risk criminal charges for operating without a valid license, and any accident during that period will not be covered by your auto insurance policy.

New Hampshire requires a Medical Examination Report completed by a licensed physician, preferably a neurologist familiar with your seizure disorder. The form must certify that you have been seizure-free for at least 6 consecutive months and that your condition is controlled through medication, surgery, or other documented treatment. The physician must also state whether any seizures occurred exclusively during sleep, as New Hampshire allows case-by-case evaluation for drivers with purely nocturnal seizure patterns that have been stable for at least one year. The medical report must be submitted directly to the NH Division of Motor Vehicles Medical Unit, not through your insurance company or primary care provider. Senior drivers should confirm that their neurologist includes medication compliance history and any recent EEG results in the certification, as the DMV medical review panel evaluates treatment stability in addition to seizure-free duration. A gap in medication records or inconsistent dosing can delay reinstatement even if the 6-month period has passed.

Yes. New Hampshire insurance law requires policyholders to report any material change in health status that affects their ability to operate a vehicle safely, and a seizure disorder diagnosis meets that threshold. Failure to disclose a seizure disorder—even if you stop driving during treatment—can void your policy retroactively, meaning the insurer can deny claims from before the diagnosis was discovered. You must report the diagnosis when it occurs, not when you resume driving. Most carriers require written notification within 30 days of diagnosis, though policy language varies. If you were involved in an accident before diagnosis and the insurer later discovers you had seizure symptoms or a prior episode you didn't disclose, they can rescind coverage and pursue recovery of any claims paid on your behalf. Senior drivers often assume that stopping driving temporarily satisfies disclosure requirements. It does not. Your policy remains active as long as you own the vehicle and maintain coverage, and non-disclosure during that period is treated as material misrepresentation under New Hampshire insurance contract law.

Most New Hampshire insurers will non-renew or cancel a policy immediately upon notification of a seizure disorder diagnosis, then offer reinstatement only after you provide proof of DMV medical clearance and license restoration. Upon reinstatement, expect rate increases ranging from 25% to 60% compared to your pre-diagnosis premium, with senior drivers aged 70 and older typically facing the higher end of that range. Some carriers classify controlled seizure disorders as high-risk medical conditions and move the policy into a non-standard or assigned risk tier. State Farm, Progressive, and GEICO have underwriting guidelines that allow reinstatement for drivers with documented 6-month seizure-free periods, but each requires annual physician recertification as a condition of continued coverage. If you cannot secure coverage in the standard market after reinstatement, New Hampshire does not operate a state-assigned risk pool for medical conditions. You will need to work with an independent agent who specializes in high-risk placement to access surplus lines carriers. These policies cost 40–80% more than standard rates and often require higher liability limits as a condition of issuance.

Yes, and you should. Dropping coverage entirely during the 6-month waiting period creates a coverage gap that will increase your rates significantly when you reinstate your license—most carriers add 15–30% for any lapse longer than 30 days. Instead, remove yourself as a listed driver on the policy and maintain comprehensive and liability coverage on the vehicle. If you live alone and no one else will drive the vehicle, contact your insurer to request a parked vehicle or storage policy. This reduces your premium by 40–70% while keeping continuous coverage intact. If a spouse or family member will drive the vehicle during your waiting period, they must be listed as the primary driver and you must be formally excluded as an operator. Senior drivers who own their vehicles outright sometimes consider canceling collision coverage during the waiting period to reduce costs. This is financially sound if the vehicle is worth less than $4,000, but keep liability and comprehensive in place—liability protects household assets if someone else drives your car, and comprehensive covers theft, weather damage, and vandalism while the vehicle sits unused.

You must stop driving immediately and report the seizure to both the New Hampshire DMV and your insurance carrier within 10 days. The 6-month waiting period resets from the date of the new seizure, and your license will be medically suspended until you complete another seizure-free period and obtain updated physician certification. Failure to self-report a post-reinstatement seizure is a criminal offense in New Hampshire under RSA 263:12-a, which requires drivers to notify the DMV of any medical condition that impairs safe operation. If you are involved in an accident and the insurer discovers an unreported seizure occurred within the prior 6 months, they will deny the claim and may refer the matter to the state for prosecution. Senior drivers managing seizure disorders with medication should keep detailed logs of dosing and any breakthrough symptoms. If a seizure occurs due to a temporary medication interaction or illness—not a failure of seizure control—your neurologist can petition the DMV for an expedited review, though the standard 6-month period still applies in most cases.
