Vehicle Emissions Inspections in Texas
Enhanced vehicle emissions inspections were implemented in affected areas in Texas to improve air quality and are integrated with the annual safety inspection program and operated by the Texas Department of Public Safety (DPS) in conjunction with the Texas Commission on Environmental Quality (TCEQ). Enhanced inspections began in Collin, Dallas, Denton, Harris, and Tarrant Counties on May 1, 2002, and in Brazoria, Ellis, Fort Bend, Galveston, Johnson, Kaufman, Montgomery, Parker, and Rockwall Counties on May 1, 2003. Travis and Williamson Counties implemented enhanced inspections on September 1, 2005, and El Paso County on January 1, 2007.
On March 1, 2015, the State of Texas stopped issuing vehicle inspection stickers and transitioned to a “Two Steps, One Sticker” vehicle inspection and registration program. Vehicles owners must pass the annual safety inspection before going to register the vehicle. More information on the Two Steps, One Sticker program is available at www.TwoStepsOneSticker.com.
