The Wisconsin Department of Transportation (WisDOT) requires that all CDL applicants must be able to read and understand English language sufficiently to converse with the general public, understand highway traffic signs and signals, respond to official inquiries, and make entries on reports and records.

However, if you have difficulty reading or understanding English, you can bring an interpreter with you to translate the questions and answers. The interpreter must be at least 18 years old and cannot be a CDL holder or have any interest in your test or the outcome of your test. The interpreter must also sign an affidavit stating that they will truthfully and accurately translate the questions and answers.

Some common accommodations include extra time to complete the test, a separate testing area, or the use of adaptive equipment.

You will need to provide documentation from a qualified medical professional that supports your request for accommodations. The documentation should describe your disability or medical condition and explain how it impacts your ability to take the Class A CDL written test without accommodations.

The WisDOT will review your request and documentation and determine what reasonable accommodations can be made. They will then work with you to schedule a testing appointment that accommodates your needs.
If you fail the Class A CDL written test, you are allowed to retake the test. In Wisconsin, you can retake the written test as many times as necessary until you pass; however, there are some limitations on how often you can take the test.

In Wisconsin, you are required to wait at least one day before retaking the written test. If you fail the test three times, you are required to wait at least 14 days before taking it again. If you fail the test six times, you must wait at least 28 days 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. The fee for the Class A CDL written test in Wisconsin is \$35.

To improve your chances of passing the written test, be sure to study and prepare thoroughly. You can find study materials and practice tests online or through commercial driving schools.
