Commercial Driver's License Testing and Commercial Learner's Permit Standards

Notice of regulatory guidance and applicability of "tank vehicle" definition.

On May 9, 2011, FMCSA published a final rule titled "Commercial Driver's License Testing and Commercial Learner's Permit Standards." Among other things, the rule revised the definition of "tank vehicle." The change required additional drivers, primarily those transporting certain tanks temporarily attached to the commercial motor vehicle (CMV), to obtain a tank vehicle endorsement on their commercial driver's license (CDL). The Agency has since received numerous questions and requests for clarification. This notice responds to questions about the new definition and the compliance date for drivers to obtain the tank vehicle endorsement.
