Ohio Rev. Code § 4510.23
When any person having a driver's or commercial driver's license is adjudicated incompetent for the purpose of holding the license, as provided in section 5122.301 of the Revised Code, the probate judge shall order the license of the person delivered to the court. The court shall forward the license with notice of the adjudication to the registrar of motor vehicles. The registrar shall impose a class F suspension of the person's driver's or commercial driver's license for the period of time specified in division (B)(6) of section 4510.02 of the Revised Code. The suspension shall remain in effect until receipt of written notice by the head of the hospital, or other agency which has or had custody of such person, that such person's mental illness is not an impairment to such person's ability to operate a motor vehicle, or upon receipt of notice from the adjudicating court that such person has been restored to competency by court decree.
