Testing process, costs, and registration timing
1. Visit a certified emissions station
Bring the vehicle and proof of financial responsibility. The station generally performs an OBDII test and checks emissions-control components required by the program.
2. Pay the station charge
DPS currently lists maximum charges of $18.50 in Dallas-Fort Worth and Houston-area counties and $11.50 in El Paso, Travis, and Williamson counties. Commercial inspections may cost up to $40.
3. Complete registration
Inspection results are transmitted electronically. After a passing result is recorded, complete registration through TxT, TxDMV, a participating location, or the county tax assessor-collector as eligible.
If the vehicle fails
Use the inspection report
Review the Vehicle Inspection Report and diagnostic trouble codes. A lit check-engine light, incomplete readiness monitors, emissions-control failure, or communication problem can prevent a passing result.
Repair and retest
Repair the underlying issue, complete any required drive cycle, and return for retesting. Keep receipts because they may be needed for assistance, waiver, or dispute procedures.
Inspection program replacement fee
Although most non-commercial safety inspections ended, Texas retained the former state inspection-related amount as an inspection program replacement fee collected with registration. DPS states the standard amount is $7.50, while qualifying new vehicles receiving two years of initial registration are charged $16.75. Commercial vehicles that still pay for a safety inspection are exempt from this replacement fee.
