FMCSA's December 8, 2016 final rule separated the duration of commercial-driver training from its required content. It specified no minimum theory or behind-the-wheel hours, while preserving instruction and assessment for covered entry-level applicants. That distinction is essential: the absence of a federal time floor was not permission to omit the curriculum or issue an unsupported completion certificate. [2016-28012][2016-03869]

For theory, providers had to cover all elements of the applicable curriculum. The trainee needed an overall score of at least 80 percent on the theory assessment. For Class A and Class B driving instruction, the rule described range and public-road segments, with required maneuvers demonstrated proficiently to the satisfaction of the training instructor.

The proposal published March 7 had taken a different approach to driving time. It contemplated 30 hours for Class A and 15 for Class B, alongside road and range subrequirements and a proficiency condition. Those numbers belong to the proposal, not the final mandate. Comparing the two documents shows the design change within a single agency proceeding, not independent confirmation of training effectiveness. [2016-28012][2016-03869]

The rule addressed certain first CDL applications, upgrades and first hazardous-materials, passenger or school-bus endorsements, with exceptions rather than universal retraining. Its original dates were February 6, 2017 for effectiveness and February 7, 2020 for compliance. Those are separate milestones in the historical document; neither turns the December publication into an immediate training deadline for every driver. [2016-28012][2016-03869]
