Dillon Compliance Checklist - Medical Card Renewal

After your driver completes their DOT physical, the medical examiner submits results to the FMCSA National Registry within 24 hours. The driver receives a hard copy of the medical certificate. In Montana, drivers must file a copy with the Montana Highway Patrol within 15 days to maintain CDL downgrade prevention. Track both the examiner submission and state filing.

Best Practice: Document every compliance action with date, responsible party, and outcome. Documentation is your defense during Montana Highway Patrol audits.

Common Medical Card Renewal Violations in Montana
