The U.S. Census Bureau places the city of Bartlett in Williamson and Bell counties. About 697 of its residents live in Bell County, outside the emissions program (2020 Census): a vehicle registered there needs no emissions test. A vehicle registered in Williamson County needs a passing emissions test to renew its registration.

Motorists with vehicles registered in Brazoria, Collin, Dallas, Denton, Ellis, El Paso, Fort Bend, Galveston, Harris, Johnson, Kaufman, Montgomery, Parker, Rockwall, Tarrant, Travis, and Williamson Counties will not be eligible to renew their vehicle's annual registration if the vehicle has not passed its annual emissions inspection or complied with the vehicle emissions inspection program requirements.
Not required to inspect: electric vehicles, diesel vehicles, motorcycles, and mopeds.
Who this affects
About 697 people live in the part of Bartlett outside the program. If you are one of them and your vehicle is registered at that address, your county has no emissions test. If you move within Bartlett across the county line, the county of the new address applies once the vehicle is registered there. Vehicles that the program does not test anywhere (electric vehicles, diesels, motorcycles and mopeds) are not tested on either side.

Bartlett questions
Do I need an emissions test if I live in Bartlett?
It depends on the county your vehicle is registered in. Williamson County is in the emissions program; Bell County is not.
How do I know which county my Bartlett address is in?
Check the county on your registration renewal notice, or ask the county tax office. A mailing address with the city name can lie outside the city limits, or in a different county.
