However, it's important to note that the skills test (the driving portion of the CDL exam) is only administered in English. So even if you take the written test in another language, you will still need to be proficient in English to pass the skills test and obtain your CDL.
If you do choose to take the written test in a language other than English, be sure to let the licensing examiner know before you start the exam. They will provide you with an appropriate translation or interpreter, if needed.
Some examples of accommodations that may be available include extra time to complete the test, a separate testing room, or a sign language interpreter. To request accommodations, you will need to contact the Hawaii Department of Transportation's CDL office and provide documentation of your disability.
It's important to make your request for accommodations as early as possible, as it may take some time to arrange for the necessary accommodations. The CDL office will work with you to determine what accommodations are appropriate and available.
If you fail the written test, you will need to wait at least one business day before you can retake it. If you fail the test three times, you will need to wait at least 30 days before you can take it again.
It's important to note that there may be a fee associated with retaking the test. You should check with the Hawaii Department of Transportation's CDL office to find out what the fee is and what forms of payment are accepted.
When you retake the test, you will be given a different version of the test than the one you took previously. This is to ensure that you have a fair opportunity to pass the test.
