Which counties
Registered in an emissions county but living or driving elsewhere

Short answer
The emissions rule follows the county of registration. DPS publishes exceptions for vehicles registered in a program county that are kept or driven in a county outside it, such as branch-office fleet vehicles, hunting vehicles, owners who have moved, and students away at school.
The exceptions DPS lists
DPS calls the program counties "affected" counties. Its exemption page names three situations.
The vehicle is not and will not be primarily driven in a program county
Company fleet vehicles owned by business entities registered at a central office located in an affected county but operated from branch offices and locations in non-affected counties on a permanent basis.
Hunting and recreational vehicles registered to the owner in an affected area, but permanently maintained on a hunting property or vacation home site in a non-affected county.
The owner has moved away
the vehicle registration indicates it is registered in an affected county, but the owner has moved, does not currently reside in, nor will primarily operate the vehicle in an affected county.
Away for the whole registration period
Examples of this exception include vehicles operated by students enrolled at learning institutions, vehicles operated by persons during extended vacations, or vehicles operated by persons on extended out-of-county business.
Under this exception the vehicle will be re-inspected at a vehicle inspection station certified to do vehicle emissions testing immediately upon return to an affected county.
What the cases look like
Read plainly, the DPS cases describe situations like these: a company truck registered at a head office in Dallas County but run permanently from a branch in a county without testing; a hunting vehicle registered in Harris County but kept on a ranch in a county outside the program; a family that moved from Travis County to a county without testing and does not drive the vehicle back; a student who keeps the car at a college outside the program counties for the whole registration period. In the last case DPS expects the vehicle to be tested as soon as it returns to a program county.
A caution about the wording
The DPS exemption page still describes these cases in terms of the annual safety inspection, which non-commercial vehicles no longer need since January 1, 2025. Ask a DPS vehicle inspection office or your county tax office how the exception is handled today before you rely on it.
A vehicle registered in an affected county may receive a safety inspection at a vehicle inspection station in a non-affected county if:
As a reminder, as of Jan. 1, 2025, non-commercial vehicles no longer need a vehicle safety inspection prior to registration.
If you moved for good
If you moved to another Texas county, update the address on your motor vehicle record. TxDMV says an updated address helps you receive the renewal notice, and that not renewing is against the law.
Updating your address will help ensure you receive your registration renewal notice. Failure to renew your registration is against the law and may result in a fine.
If you moved out of Texas, the vehicle should be registered where you now live; TxDMV makes an exception for full-time students and active military.
You must register your vehicle in the state or jurisdiction where you currently live, unless you are a full-time student or active military.
Temporarily out of state
For a vehicle that is out of Texas when the registration is due, DPS allows self-certification for a short list of owners. The vehicle then needs its Texas inspection within three days of coming back.
The self-certification process is limited to: Active Duty Military Full-Time Students Seasonal Texans, RVers Apportioned Vehicles Elected Congressional Officials
Once you return to the state, you must complete a Texas vehicle inspection within three days of arrival at your home, duty station or destination.
