Conn. Agencies Regs. § 14-164c-13a
No motor vehicle which has failed an emissions inspection shall be inspected or reinspected without proof that the vehicle has been repaired. Such proof shall include presentation of the vehicle inspection report indicating thereon any repairs made to the vehicle by the operator or owner thereof, and indicating any repairs made to the vehicle by a repair facility licensed in accordance with chapter 246 of the Connecticut General Statutes. If repairs have been made to a vehicle by a licensed repair facility, the inspection report shall show the name, address and license number of the repairer, the cost of new parts and labor for emissions related repairs, and a description of the emissions related repairs performed. In addition, each such licensed repair facility shall provide the vehicle owner or operator with a copy of the repair invoice identified in section 14-65h of the Connecticut General Statutes, and such invoice shall be presented at the time of inspection or reinspection. Except as provided in subsection (a) of section 14-164c-9 a of the Regulations of Connecticut State Agencies, an inspection fee shall be required prior to any inspection of a vehicle which has previously failed an emissions inspection.
