Texas emissions testing 2025 refers to the state of Texas’s requirement for vehicles to undergo emissions testing beginning in 2025. The Texas Legislature passed House Bill 3281 in 2021, which requires the Texas Commission on Environmental Quality (TCEQ) to implement an emissions testing program in certain counties. This program is designed to improve air quality and reduce vehicle emissions, particularly in areas that do not currently meet federal air quality standards.
The emissions testing program will be phased in over several years, starting with vehicles registered in certain counties that have populations of more than 500,000 people. The program will eventually expand to include vehicles registered in all counties in Texas. Vehicles that are subject to the emissions testing program will be required to pass an emissions test every two years in order to renew their registration. Vehicles that fail the emissions test will be required to undergo repairs to reduce their emissions before they can be registered.
