I received a quick reply from Dan Jalbert, DMV Emissions Co-ordinator. The system changes to recognize the Composite emissions exemption along with all the other DMV changes that took place on July 1st are still being processed. I provided my CT VIN and registration plate number to Dan and he manually updated the exempt file, as my due date was August 15th.
You may want to check your emissions test due date and as the date approaches, contact Dan if the system changes have yet to be made. Provide the CT VIN and registration plate number. Dan also mentioned the abbreviations for Composite will be recognized.
