Ohio Rev. Code § 4503.78: Implementing new specialty license plates.

Except as may otherwise be specifically provided by law, the registrar of motor vehicles is not required to implement any legislation that creates a specialty license plate and provides for its issuance until the registrar receives written statements from not less than one hundred fifty persons, indicating that they intend to apply for and obtain such license plates for their motor vehicles. The registrar may require such statements to be made on a form the registrar provides.
