Official Texas DOT & FMCSA Inspection Station in San Antonio | Commercial Compliance

Automotive Brake & Clutch is an authorized Texas DPS Certified Inspection Station. We specialize in mandatory Texas DOT Inspections and FMCSA Annual Federal Inspections for semi-trucks, commercial trailers, and business fleets at our San Antonio and Kirby facility.

As lead technical advisors with decades of field-proven mechanical background, our team ensures every fleet assessment meets strict safety standards. If repairs are needed to pass compliance, we provide transparent diagnostic repair estimates for air brakes, lighting, steering gear, and drivetrain components.

🛑 Expert Installation & Field Note

Drawing from our shop experience specializing in heavy-duty brakes since 1985, air brake out-of-adjustment violations constitute the single highest cause of commercial vehicle out-of-service orders during roadside enforcement audits. Standard automatic slack adjusters can fail to compensate when S-cam pushrod alignment falls out of spec or if drums experience severe heat checking. Pre-screening these tolerances before your scheduled safety inspection protects your drivers from costly fines and prevents operational down-time on the highway.

Official Inspection Requirements & Checklist

Commercial Air Brake System Compliance

During a Texas DOT or FMCSA inspection, the air brake system is the most heavily scrutinized component. We verify the mechanical layout of the compressor, air dryer, and brake chambers to ensure zero system leaks. Our certified team inspects S-cam stroke adjustments and slack adjuster travel limits to guarantee your fleet meets all mandatory federal safety stopping distances.

San Antonio DOT Inspection FAQ

Are commercial safety inspections still required in Texas in 2026?
Yes. While non-commercial passenger car safety inspections were eliminated by Texas lawmakers, annual safety inspections remain completely mandatory for all commercial motor vehicles, trucks, trailers, and combinations operating over 10,001 lbs GVWR to maintain strict state DOT and federal FMCSA compliance.
What is the penalty for operating a commercial truck with an expired DOT safety inspection?
Operating a commercial vehicle with an expired inspection can lead to severe fines from the Texas Department of Public Safety (DPS), safety points against your carrier SMS score, or an immediate out-of-service designation during unexpected roadside checks. Keeping your fleet aligned with our recurring preventative scheduling entirely prevents these penalties.
