Is 49 CFR 391.51(a) an acute or critical violation?

It is a critical violation on the FMCSA acute/critical list in 49 CFR Appendix B to Part 385. Critical means it is scored when auditors find a pattern of noncompliance.

Does 49 CFR 391.51(a) automatically fail a new-entrant audit?

No. It is not on the 16-item automatic-failure list in 49 CFR 385.321, but it still adds points against the relevant audit factor and can contribute to an inadequate rating.

§ 391.51(a) — critical

49 CFR 391.51(a) in a new-entrant safety audit

49 CFR 391.51(a) is a critical regulation on the FMCSA new-entrant audit list (49 CFR Appendix B to Part 385): Failing to maintain driver qualification file on each driver employed.

What does this regulation mean?

This is a critical violation of 49 CFR 391.51(a): failing to maintain driver qualification file on each driver employed. A critical regulation relates to management or operational controls; it is scored when auditors find a pattern (more than one occurrence, generally at least 10% of the records examined).

How do I pass the audit on this point?

Keep the records that prove compliance current and complete before the audit, and be ready to show them for the period the auditor reviews. Verify the exact current requirement at ecfr.gov, because the regulations are amended over time.

Which audit factor is this scored under?

§ 391.51(a) is scored under the Driver factor (Parts 382, 383, and 391) of the new-entrant safety audit. Points for Driver come from acute and critical violations of Parts 382, 383, and 391. Several Driver-factor violations are on the 16-item automatic-failure list in 49 CFR 385.321, so a single occurrence can fail the audit on its own.
