'DOT Doctor Shopping': Drivers who fail a DOT physical at an occupational clinic because of severe sleep apnea or 210/120 blood pressure sometimes drive across town the next day to a chiropractor or clinic on the National Registry and check 'No' on every health history box to get a 2-year medical card!
Recommended Action Plan for Texas Claimants
Subpoena not just the 1-page wallet DOT Medical Card, but the full 5-page 'Medical Examination Report (MER) Form MCSA-5875' AND the driver's CPAP SD-card compliance printout.
