However, if English is not your primary language, you may be able to use an interpreter during the test. The interpreter must be at least 18 years old and cannot be a family member or friend. Additionally, the interpreter must sign an affidavit stating that they will accurately translate the questions and answers during the test.

To request accommodations, you must submit a written request to the MVD and provide documentation of your disability.

It is important to note that each time you retake the test, you will need to pay a fee. Therefore, it is in your best interest to prepare adequately and pass the test on your first attempt. You can find study materials and resources on the MVD website or through other CDL training providers.
