In West Virginia, the Class B CDL written test is only available in English. The state requires that all applicants be able to read and understand English in order to pass the test and obtain a CDL. This is because all road signs, signals, and other important information on the road are in English. Additionally, it's essential for drivers to be able to communicate with law enforcement officers, other drivers, and dispatchers in English in case of an emergency. However, if an applicant has difficulty with reading or writing, they may request assistance from a translator or an interpreter to help them understand the questions on the test.

The DMV offers a variety of accommodations, such as a reader, a scribe, extended time, and audio recordings of the test. The type of accommodation provided will depend on your specific needs and the availability of resources at the testing location.

It's important to note that you must still meet all other requirements for obtaining a CDL, such as passing a vision test and meeting medical certification requirements. Additionally, accommodations are not provided for the skills test portion of the CDL exam, as this portion requires physical demonstration of driving skills.

If you fail the Class B CDL written test in West Virginia, you may retake the test. However, you must wait at least one day before retaking the test. The West Virginia DMV charges a fee for each attempt at the written test, so you will need to pay the fee again before retaking the test.
