Commercial Driver License Testing

AAMVA offers a Model Commercial Driver’s License (CDL) Manual for the current version of the CDL exam and the new, modernized version. The manuals were developed by jurisdiction members who are members of the Test Maintenance Subcommittee (TMS) and the International Driver Examiner Certification (IDEC) Board and approved by the Federal Motor Carrier Safety Administration (FMCSA). The manuals are intended to prepare an applicant for the licensing and knowledge/skills testing processes and are not a substitute for a certified commercial motor vehicle driver training program. The model manuals provide uniformity between jurisdictions by ensuring every applicant is provided the same information regarding the CDL Knowledge and Skills tests.  The TMS and IDEC Board, in association with AAMVA staff and other experts, work to ensure that examiners and CDL applicants have the information they need to ensure consistent results and improve highway safety.

Jurisdictions may offer the modernized version, the current version, or both versions of the CDL exam as there is no mandate to offer the modernized test. Jurisdictions may determine the version(s) that work best for them. AAMVA will support them with the necessary training and materials.
