Program Integrity

DMV has taken several steps to detect instances of fraud in the emissions testing program and to protect you from fraudulent activities. The program relies on state-of-the-art technology, including inspector Biometric login for identity verification, with surveillance cameras that photograph and record a video snapshot on each emissions test. In addition, each facility, the testing equipment, and the inspector(s) will be audited every day by the DMV and Program Administrators using sophisticated, automated, and physical audit procedures.

Any Test Center or inspector engaging in any fraudulent activities will be subject to enforcement action. Enforcement actions can range from program suspension to expulsion as well as legal action.

If you suspect fraud, please call the DMV at 860-263-5335. Likewise, Test Centers are required to report any solicitation of bribery related to passing a failing vehicle. Solicitation, offering and/or acceptance of a bribe to pass a vehicle is illegal and subject to prosecution.

Tampering with Emissions Control Systems is Illegal. The Clean Air Act prohibits tampering with emission control systems originally installed and certified by vehicle manufacturers. Tampering is defined as the removal, disconnection, or modification of any emissions control systems, which renders one or more components ineffective. Examples include, but are not limited to, the removal of the catalytic converter, or light for the MIL indicator, bypassing the Exhaust Gas Recirculation (EGR) valve, Air Injection, or Diesel Exhaust Fluid (DEF) systems, etc. Please be advised that tampering or the installation of devices that bypass, defeat, or otherwise render the vehicle’s emissions control systems inoperative, including the use of simulators with the intent to circumvent or defraud the required OBD test for the State of Connecticut, is illegal and subject to prosecution and civil penalties.
