Connecticut Emissions Program
Icon - General Information Heading - General Information

 

How Is the Program Different?

The Connecticut Emissions Program uses auto repair shops, service stations, and car dealers in the statewide network with trained inspectors conducting emissions tests.

Repairs can be done in the same test center where vehicles are tested, at a repair facility of your choice or you can repair the vehicle yourself. However, to be eligible for a waiver your repairs must be performed by a Certified Emissions Repair Facility.

Another change is that stickers will no longer be issued and the dates on existing stickers are no longer valid for testing. You can find your test date online, via phone at 1-888-828-8399. In most cases, you will receive an official notification letter with a generous time period before your vehicle’s test date.  If you recently purchased a used vehicle that was registered in Connecticut, you will not receive a notification letter. However, it is your obligation to have your vehicle tested within 30 days of its registration date with or without a notification letter. The program also uses a registration enforcement system where non-compliant vehicles cannot be registered and existing registrations will not be renewed.

Emissions for vehicles that are 1995 and older will be measured by inserting a sensor-probe in the tailpipe. Some vehicles will be driven on a dynamometer, a treadmill-type simulator of real-world driving conditions. For vehicles model year 1996 or newer, the Certified Testing Inspectors will plug a scan tool into the vehicle's On-Board Diagnostic (OBD) computer system to download data and determine if emissions components are malfunctioning.

 

 

Vehicle emissions testing is the State's most effective way to improve air quality.
