Do I Need an Inspection To Renew My Tags in Connecticut?
Yes, emissions testing is required to renew vehicle registration in Connecticut for most vehicles.
Connecticut eliminated registration stickers in 2010. Previously, the state used windshield stickers from 2006 to 2010, but no physical stickers are currently issued or required to be displayed on vehicles.
Connecticut law directs biennial emissions inspections for vehicles subject to testing before registration renewal can be completed. The state does not require periodic safety inspections for personal vehicles as part of the standard tag renewal process.
Emissions testing applies statewide and follows a two-year testing cycle for eligible vehicles. The Connecticut Emissions Program operates through a network of privately owned testing facilities located throughout the state. Vehicle owners receive official notification notices within 45 days of their test due date.

- Vehicles younger than four model years old
