Part 384 is the rulebook for how states must run their Commercial Driver’s License programs. It connects directly to Part 383 because Part 383 tells drivers and employers what CDL standards apply, while Part 384 tells states how to issue, track, report, disqualify, and enforce CDL program requirements.

The federal rulebook for how states must operate CDL programs and share driver records.
Mainly applies to states, licensing agencies, and FMCSA, but carriers rely on the records it controls.
States must follow federal CDL standards for testing, issuing, checking, reporting, and disqualifying.
CDLIS helps states share CDL records so driver history follows across state lines.
States must report certain CDL convictions and avoid masking qualifying violations.
States must apply and share CDL disqualification actions so drivers cannot avoid consequences.
State CDL issuance, renewals, transfers, and upgrades affect whether a driver is dispatch-ready.
State CDL program noncompliance can affect licensing, renewals, transfers, upgrades, and carrier planning.
Accurate state CDL records directly affect MVR reviews, driver qualification, and dispatch decisions.
A practical checklist for MVRs, CDL status, endorsements, restrictions, medical tracking, and driver reporting.
DispatchHQ helps small carriers organize CDL checks, MVR reviews, medical-card tracking, endorsements, restrictions, Clearinghouse checks, DQ files, and driver qualification workflows so state record problems do not become roadside or audit problems.
