Such notice shall contain all necessary information for such registration and licensing including a breakdown of all charges to be paid by the owner and shall contain instructions as to the procedure for renewal upon presentation to a motor license agent or by return mail to the Commission's state office. The form of the notice shall be determined by the Commission. Use of a postcard type renewal notice is specifically permitted. On the back of such registration notice form there shall be an explanation of the apportionment of all license fees and penalties collected and their disposition. Such explanation shall include information as to all charges and fees included in the total license fee or incident to the registration of a vehicle. If the owner chooses the option of receiving these services through the mail, either from the Commission or a motor license agent, he shall be instructed to pay the final total listed. The cost of mailing shall be One Dollar ($1.00) for license plates and fifty cents ($0.50) for decals, titles or other forms or devices provided in this act. Provided, that the Commission may adjust any mailing costs as deemed appropriate to allow for increased or additional fees charged by the United States Postal Service.
Failure by any applicant to receive notification of renewal as provided by this act shall not excuse the applicant from properly obtaining any registration or license at the proper time by presenting proof of ownership to the Commission's state office or to a motor license agent.
