If you choose to take the test in a language other than English, you will need to bring an interpreter with you to help with the testing process. The interpreter must be at least 18 years old, not related to you, and must not have any financial interest in your passing or failing the test.
It is important to note that if you take the written test in a language other than English and pass, your CDL will be issued with a restriction stating that you are only authorized to operate a commercial vehicle if it is equipped with a translator device or if an interpreter is present. If you choose to remove this restriction in the future, you will need to retake the written test in English and pass it.
To request accommodations, you will need to fill out the "Request for Reasonable Accommodation" form, which is available on the Department of Licensing's website. The form must be completed by a qualified professional who can provide documentation of your disability and the specific accommodations that are necessary.
Some examples of accommodations that may be provided include extended testing time, a separate testing room, or the use of assistive technology such as a screen reader or magnifier.
It is important to note that accommodations are provided on a case-by-case basis, and not all requests will be granted. The Department of Licensing will review each request and determine what accommodations are appropriate based on the individual's disability and the requirements of the written test.
If you fail the written test, you can retake it as soon as the next day. However, if you fail the test three times within a two-year period, you will be required to wait at least 30 days before taking it again. If you fail the test four or more times within a two-year period, you will be required to wait at least 6 months before taking it again.
It is important to note that each time you retake the written test, you will need to pay the testing fee again. Additionally, if you fail the test multiple times, it may be a good idea to seek additional study materials or consider taking a CDL training course to better prepare for the exam.
Once you pass the written test, you will need to complete additional requirements in order to obtain your Class A CDL license, such as passing a skills test and meeting other eligibility requirements.
