The state inspection requirements

(a) The owner of any motor vehicle registered in this state, which is not within the exempted classes of motor vehicles set forth in subsection (c) of section 14-164c of the Connecticut General Statutes, shall present such motor vehicle for periodic emissions inspection at such times as provided in an inspection schedule established by the commissioner. The purpose of such inspection shall be to determine whether such vehicle is in compliance with the emissions standards as determined by the Commissioner of Environmental Protection. The fee for such inspection shall be as established by the commissioner in accordance with the provisions of subsection (k) of section 14-164c of the Connecticut General Statutes. (1) Unless otherwise directed by the commissioner, the period of inspection frequency for all non-exempt motor vehicles shall be two years. The commissioner may, for the more effective administration of the enhanced inspection program, adjust or alter the period of inspection frequency as stated herein, or may extend the time scheduled for the inspection of any motor vehicle. The commissioner shall, in the case of any such changes that are directed, provide appropriate notification to the owners of all motor vehicles affected thereby. (2) A commissioner's certificate may be issued for good cause shown when a motor vehicle cannot be presented for inspection at the time scheduled for periodic inspection. A request for a commissioner's certificate shall be made in writing by the owner, except that a lessee or other person rightfully entitled to possession or custody of a vehicle may make the request, and proof of such right to possession or custody, may be required. No commissioner's certificate shall be issued to extend the time for the inspection for more than one month from the previously scheduled time, provided a vehicle continuously outside of this state for an extended period of time as determined by the commissioner may be issued a commissioner's certificate extending the time for the inspection to no more than thirty (30) days after the return of such vehicle to this state. (3) If a person presents a motor vehicle for inspection more than thirty (30) days after the time for periodic inspection established by the commissioner, a late fee of twenty dollars ($20.00) shall be assessed as provided in subsection (k) of section 14-164c of the Connecticut General Statutes. (4) For the purpose of determining exemption eligibility of a motor vehicle manufactured twenty-five or more years ago pursuant to subsection (c) section 14-164c of the Connecticut General Statutes, "twenty-five or more years ago" shall mean the number of years arrived at by subtracting the model year of the motor vehicle seeking the exemption from the current calendar year. (b) Used motor vehicles not otherwise exempt from inspection which are not in compliance shall be presented for initial inspection as provided in subsection (a) of this section prior to the issuance of permanent registrations for such used motor vehicles.
