However, it is important to note that the skills test must be taken in English. This is because it is essential for drivers to be able to communicate effectively with law enforcement officers and other drivers while operating a commercial vehicle on public roads.
If you need to take the written test in a language other than English, you should contact your local DMV office to confirm which languages are offered and to schedule an appointment for your test. It is also recommended that you study the Nebraska Commercial Driver License Manual in your preferred language before taking the test to ensure you are fully prepared.
Some examples of accommodations that may be available include:
- Providing the test in an alternative format, such as braille or large print.
- Allowing additional time to complete the test.
- Providing a reader or sign language interpreter.
To request accommodations, you should contact the DMV office where you plan to take the test and inform them of your disability and what accommodations you require. You will likely need to provide documentation from a qualified medical professional that verifies your disability and explains how it affects your ability to take the test under standard conditions.
It is important to request accommodations well in advance of your scheduled test date to ensure that they can be arranged in a timely manner.
If you fail the written test three times, you will need to wait at least 14 days before you can take it again. If you fail the test a fourth time, you will need to wait at least 30 days before taking it again.
It is important to note that there is a limit to the number of times you can take the written test. If you fail the test eight times, you will not be allowed to retake it again for a period of six months.
To improve your chances of passing the Class B CDL written test, it is recommended that you study the Nebraska Commercial Driver License Manual thoroughly and take practice tests. You may also want to consider enrolling in a commercial driver training program.
