Texas does not require a statewide license for diesel technicians for general repair work. However, vehicle emissions inspectors must be licensed by the Texas Department of Public Safety (DPS). Employers commonly require ASE certifications. Verify with the Texas DPS at dps.texas.gov for emissions inspection requirements.
