Fort Worth car registration, emissions and towing rules
Most of Fort Worth is in Tarrant County, and vehicles there are registered through the Tarrant County tax assessor collector. Use the county of your own address; TxDMV keeps the list of county tax offices. (source: Texas Department of Motor Vehicles)
Tarrant County is one of the 18 Texas emissions counties. Gasoline vehicles 2 to 24 years old need a passing emissions test before registration renewal. (source: Texas Department of Motor Vehicles)
TCEQ caps the station fee for an OBD emissions test in Tarrant County at $18.50. (source: Texas Commission on Environmental Quality)
You can renew up to 90 days before expiration, and TxDMV says a required emissions test must be done within that 90 day renewal period. (source: Texas Department of Motor Vehicles)
If your car is towed here
Statewide maximums apply unless a local rule sets lower ones. (source: Texas Department of Licensing and Regulation)
If your car is towed from a spot in Tarrant County, the tow hearing is in any justice court in Tarrant County, the county it was towed from (Occupations Code 2308.453). (source: Texas Legislature)
