PRACTICE TEST QUESTIONS AND ANSWER SOURCES:
The pool of questions used to produce this practice test have been independently created by CDL Digest and come directly from Code of Federal Regulations (Title 49 – Transportation) and the information provided in AAMVA’s “2005 CDL Test System (July 2010 or newer Version) Model Commercial Driver Manual”.
These are the same sources that all 50 State Driver Licensing Agencies (SDLA) are required to use by federal regulation (49 C.F.R. 383.133) to develop the pool of questions for all written tests needed for a person to obtain a commercial learner’s permit (CLP), commercial driver’s license (CDL), and/or any federally authorized endorsements.
Note: The above listed source information is static, meaning changes to the information used to create the pool of questions that your State Driver Licensing Agency (SDLA) uses for the actual written test have been extremely rare over the decades. Due to the static nature of the source information, you may see practice test questions and answers in this practice test that are very similar, if not identical to the questions and answers on the actual written test. If this occurs, it is purely coincidental. CDL Digest is not affiliated with the AAMVA or any government agency.
PRACTICE TEST DIFFICULTY:
The source material used by CDL Digest to develop these practice test questions is very technical. Relying solely on the practice tests we have produced will not be enough to successfully pass the actual written tests. You will NEED to study in order to successfully pass these practice tests and the actual written tests.
