Frequently Asked Questions
What documents does FMCSA look for during a compliance review?
FMCSA investigators examine: driver qualification files for every current and recently terminated CDL driver (employment applications, CDL copies, MVR reviews, medical certificates, previous employer verifications, drug test records, and Clearinghouse query records); drug and alcohol testing records (consortium enrollment, random testing documentation, post-accident test records, and MIS reports); hours of service records — ELD data or paper logs for the past 6 months; vehicle maintenance records including annual inspections, DVIRs, and preventive maintenance logs; and the accident register. Failure to produce required documents on demand is itself a violation.
What are the most common FMCSA compliance violations?
The most frequently cited violations in FMCSA compliance reviews are: (1) Incomplete or missing DQFs — especially missing annual MVR reviews, expired medical certificates, or no previous employer verification. (2) Drug and alcohol program deficiencies — missing Clearinghouse queries, incomplete random testing documentation, or drivers not enrolled in a testing consortium. (3) HOS/ELD violations — missing ELD records or falsified logs. (4) Vehicle maintenance failures — no current annual inspection or missing DVIRs. (5) Missing accident register entries for qualifying accidents.
How often does FMCSA audit motor carriers?
There is no fixed schedule. New entrant carriers receive a mandatory safety audit within 12 months of first operations. After that, compliance reviews are triggered by high SMS BASIC percentiles (above alert thresholds), safety complaints, post-accident investigations, or random selection. Carriers with Conditional or Unsatisfactory ratings may be reviewed within months. Carriers with satisfactory ratings and clean BASIC percentiles may go years without a review, but random selection means no carrier is ever guaranteed immunity.
How do I prepare for a DOT compliance review?
Audit all six areas before investigators arrive: (1) DQF audit — verify every CDL driver has a complete, current file with all time-sensitive documents active. (2) Drug testing audit — confirm random testing quotas are on pace, all post-accident tests were completed and documented, and every current driver has a completed annual Clearinghouse query. (3) HOS/ELD records — ensure 6 months of records are accessible. (4) Vehicle maintenance — verify all annual inspections are current and DVIRs are complete. (5) Accident register — confirm all qualifying accidents are entered. (6) Written drug policy — confirm all drivers received a copy.
