391.45A — Operating without a medical exam (no Med Card on file)
49 CFR 391 • Driver Fitness BASIC • Severity 5/10
What this violation means
Sister rule to 391.41A — driver has no DOT medical exam on file at all (not just expired). Common with new-entrant carriers and brand-new drivers. 5 SMS points, OOS.
Why this gets cited
New drivers hired without proper qualification file. Carrier records were lost or never created. Driver got CDL without DOT physical (legal in some states for intrastate-only, but not for interstate).
How to fix / prevent
Driver Qualification File (DQ File) per 391.51 must include the original Med Card and the long form (CDL drivers don't get a long form, just the card). Build DQ checklist into hire packet.
Out-of-service criteria
Yes — this violation IS out-of-service eligible. When an inspector finds 391.45A during a Level 1, 2, or 3 inspection, they can place the Driver OOS using the North American Standard Out-of-Service Criteria. OOS means the truck cannot move from the inspection site until the defect is corrected (vehicle OOS) or the driver is replaced (driver OOS). For carriers, every OOS violation adds time-weighted points to your CSA Driver Fitness BASIC — and it shows in the public SMS data within 30 days. For drivers, an OOS event stays on PSP for 3 years.
CSA / SMS impact
391.45A carries a severity weight of 5/10 in FMCSA's Safety Measurement System (SMS). Higher weights mean faster CSA percentile movement. Combined with a time-weighting factor (2× for citations within the last 6 months, decaying over 24 months), this violation can move your Driver Fitness BASIC percentile significantly if it stacks with similar citations across your fleet. The threshold for FMCSA intervention is the 65th percentile for most BASICs (50th for Hazmat and Passenger Carrier). Once you cross that, FMCSA can send a Warning Letter, Off-Site Investigation, or full Compliance Review.
How to read this: a single citation rarely puts you over threshold — it's the pattern. Track your inspection rate per power unit and aim for OOS rate under 5% (industry average is 21%).
