(R.C. § 4301.64)
(B) Whoever violates this section is guilty of a misdemeanor of the fourth degree. If an offender who violates this section was under the age of 18 years at the time of the offense, the court, in addition to any other penalties it imposes upon the offender, may suspend the offender’s temporary instruction permit, probationary driver’s license or driver’s license for a period of not less than 6 months and not more than one year. In lieu of suspending the offender’s temporary instruction permit, probationary driver’s license, or driver’s license, the court instead may require the offender to perform community service for a number of hours determined by the court. If the offender is 15 years and 6 months of age or older and has not been issued a temporary instruction permit or probationary driver’s license, the offender shall not be eligible to be issued such a license or permit for a period of 6 months. If the offender has not attained the age of 15 years and 6 months, the offender shall not be eligible to be issued a temporary instruction permit until the offender attains the age of 16 years.
