Many prospective CDL candidates do not know how to study for these tests.  Others become overwhelmed with the amount of information that they think they must know.  CDL pre tests are a great way to help you study.  A CDL pre test (or practice test) will help you evaluate what you already know and what you need to work on.  Using sample questions also helps you get accustomed to the format of the test so that there are no surprises.

The best way to study for your CDL test is to review the information in your state's CDL manual.  Make sure that you concentrate only on the areas that you are required to.  For example, if you are not planning on driving a school bus, do not waste your time with the school bus section.  If you do not know which tests you need to take, please visit our CDL Test Overview for a guide to the endorsements.
