Ohio Rev. Code § 4509.14: Reduction of excessive security - return of excess deposit.

The registrar of motor vehicles may reduce the amount of security ordered if, in his judgment, the amount ordered is excessive; provided that in any accident resulting in personal injury, the amount shall in no case be reduced to an amount less than five hundred dollars. If the security originally ordered has been deposited, the excess deposit over the reduced amount ordered shall be returned to the depositor or his personal representative forthwith.
