California runs cheapest truck inspections, faces federal funding fight

California conducted 455,237 roadside commercial vehicle inspections in fiscal 2025 at a cost of $44.89 per inspection, the lowest in the nation and nearly one of every six inspections performed across America, according to FreightWaves analysis of federal records. The state's efficiency stands out even as it faces a major enforcement dispute with federal regulators. The conflict centers on the Motor Carrier Safety Assistance Program, or MCSAP, the federal grant that funds most roadside inspections, scale house staffing, and new entrant audits nationwide. Washington withheld $841 million in MCSAP money from fiscal 2025 alone, suspended a state licensing program, and revoked 17,000 commercial driver licenses as part of the dispute. California is now suing the Transportation Secretary and FMCSA Administrator in federal court. FreightWaves analyzed 2.9 million roadside inspections and 1.24 million crash records from fiscal 2025 using federal grant obligations totaling $841 million. The data reveals contradictions in both sides' positions. The state under federal punishment operates the most productive inspection program in the country. Additionally, two-thirds of English proficiency citations that fueled the dispute never resulted in drivers being removed from service, the analysis found. For truckers, the fight matters because MCSAP funding directly pays for the inspections that affect compliance records and insurance ratings. The outcome could reshape how states balance enforcement productivity with federal expectations.
