HOUSTON, TX — Thousands of commercial drivers are currently navigating the fallout of an FMCSA decision that stripped two Houston chiropractors of their National Registry credentials, rendering their issued medical certificates void. Dr. Jenny Le and Dr. Dustin Mai were officially removed from the federal registry on April 11, 2025, after investigators found they failed to adhere to mandatory medical standards during DOT physicals.

This regulatory enforcement action impacts 15,225 commercial motor vehicle operators who received exams from these specific providers between March 2023 and March 2025. The Federal Motor Carrier Safety Administration determined that the volume of certifications issued by these individuals was statistically anomalous, prompting an investigation by the DOT Office of Inspector General. That inquiry confirmed that the required federal protocols for physical qualifications were ignored, forcing the agency to invalidate the resulting medical cards.

Drivers caught in this administrative sweep were issued formal notices requiring a new, compliant physical examination by May 10, 2025. Failure to secure a valid medical certificate by that date triggers a mandatory CDL downgrade process through state driver’s license agencies. This is a severe disruption for any CDL-A driver who relies on a clean record to remain behind the wheel and keep their freight moving.

What This Means for Drivers

Any driver who received a physical from these providers must immediately schedule an appointment with a certified medical examiner currently listed on the official FMCSA registry. Relying on an invalid certificate leaves an owner-operator vulnerable to being placed out of service during roadside inspections or at weigh stations. Fleet managers should audit their driver qualification files to ensure no personnel are operating under the now-voided certifications, as FMCSA regulations hold both the carrier and the driver accountable for maintaining current medical status.

Industry Reaction

The FMCSA maintains that this purge is essential to preserving the integrity of the medical certification process and ensuring highway safety. Chief Counsel Jesse Elison stated that the agency is committed to removing non-compliant examiners who fail to uphold the rigorous physical standards required of professional drivers. While the inconvenience to individual operators is significant, the agency views the move as a necessary step to prevent unqualified individuals from being cleared for duty on public roads. This incident serves as a stark reminder for drivers to verify the credentials of their medical providers before undergoing any examination.
