(a) Except as provided in section 14-41a, each motor vehicle operator’s license shall be renewed every six years or every four years on the date of the operator’s birthday in accordance with a schedule to be established by the commissioner. On and after July 1, 2009, the Commissioner of Motor Vehicles shall screen the vision of each motor vehicle operator prior to every other renewal of the operator’s license of such operator in accordance with a schedule adopted by the commissioner. Such screening requirement shall apply to every other renewal following the initial screening. In lieu of the vision screening by the commissioner, such operator may submit the results of a vision screening conducted by a licensed health care professional qualified to conduct such screening on a form prescribed by the commissioner during the twelve months preceding such renewal. No motor vehicle operator’s license may be renewed unless the operator passes such vision screening. The commissioner shall adopt regulations, in accordance with the provisions of chapter 54, to implement the provisions of this subsection related to the administration of vision screening.

      (b) An original operator’s license shall expire within a period not exceeding six years following the date of the operator’s next birthday. The fee for such original license shall be computed at the rate of forty-four dollars for a four-year license, sixty-six dollars for a six-year license and eleven dollars per year for any part of a year thereof. The commissioner may authorize an automobile club or association, licensed in accordance with the provisions of section 14-67 on or before July 1, 2007, to perform license renewals at its office facilities. The commissioner may authorize such automobile clubs or associations to charge a convenience fee, which shall not exceed two dollars, to each applicant for renewal.

      (c) The commissioner shall, at least fifteen days before the date on which each motor vehicle operator’s license expires, notify the operator of the expiration date. Any previously licensed operator who operates a motor vehicle within sixty days after the expiration date of the operator’s license without obtaining a renewal of the license shall be deemed to have failed to renew a motor vehicle operator’s license and shall be fined in accordance with the amount designated for the infraction of failure to renew a motor vehicle operator’s license. Any operator so charged shall not be prosecuted under section 14-36 for the same act constituting a violation under this section but section 14-36 shall apply after the sixty-day period.

      (d) Notwithstanding the provisions of section 1-3a, if the expiration date of any motor vehicle operator’s license or any public passenger transportation permit falls on any day when offices of the commissioner are closed for business or are open for less than a full business day, the license or permit shall be deemed valid until midnight of the next day on which offices of the commissioner are open for a full day of business.
