Ohio Code § 4503.101

§ 4503.101.

(A) The registrar of motor vehicles shall adopt rules to establish a system of motor

vehicle registration based upon the type of vehicle to be registered, the type of

ownership of the vehicle, the class of license plate to be issued, and any other factor

the registrar determines to be relevant.  Except for commercial cars, buses, trailers, and semitrailers that are registered

in this state and that are taxed under sections 4503.042 and 4503.65 of the Revised Code ;  except for rental vehicles owned by motor vehicle renting dealers;  and except

as otherwise provided by rule, motor vehicles owned by an individual shall be registered

based upon the motor vehicle owner's date of birth.  Beginning with the 2004 registration year, the registrar shall assign motor vehicles

to the registration periods established by rules adopted under this section. (B) The registrar shall adopt rules to permit motor vehicle owners residing together

at one address to select the date of birth of any one of the owners as the date to

register any or all of the vehicles at that residence address, as shown in the records

of the bureau of motor vehicles. (C) The registrar shall adopt rules to assign and reassign all commercial cars, trailers,

and semitrailers that are registered in this state and that are taxed under sections 4503.042 and 4503.65 of the Revised Code and all rental vehicles owned by motor vehicle renting dealers to a system of registration

so that the registrations of approximately one-twelfth of all such vehicles expire

on the last day of each month of a calendar year.  To effect a reassignment from the registration period in effect on June 30, 2003,

to the new registration periods established by the rules adopted under this section

as amended, the rules may require the motor vehicle to be registered for more or less

than a twelve-month period at the time the motor vehicle's registration is subject

to its initial renewal following the effective date of such rules.  If necessary to effect an efficient transition, the rules may provide that the registration

reassignments take place over two consecutive registration periods.  The registration taxes to be charged shall be determined by the registrar on the

basis of the annual tax otherwise due on the motor vehicle, prorated in accordance

with the number of months for which the motor vehicle is registered, except that the

fee established by division (C)(1) of section 4503.10 of the Revised Code shall be collected in full for each renewal that occurs during the transition period

and shall not be prorated. (D) The registrar shall adopt rules to permit any commercial motor vehicle owner or motor

vehicle renting dealer who owns two or more motor vehicles to request the registrar

to permit the owner to separate the owner's fleet into up to four divisions for assignment

to separate dates upon which to register the vehicles, provided that the registrar

may disapprove any such request whenever the registrar has reason to believe that

an uneven distribution of registrations throughout the calendar year has developed

or is likely to develop. (E) Every owner or lessee of a motor vehicle holding a certificate of registration shall

notify the registrar of any change of the owner's or lessee's correct address within

ten days after the change occurs.  The notification shall be in writing on a form provided by the registrar or by electronic

means approved by the registrar and shall include the full name, date of birth if

applicable, license number, county of residence or place of business, social security

account number of an individual or federal tax identification number of a business,

and new address. (F) As used in this section, “motor vehicle renting dealer” has the same meaning as in section 4549.65 of the Revised Code .
