This is because all road signs and driving instructions in the United States are in English, so it's important that drivers have a basic understanding of the language to ensure safety on the roads. If you have difficulty reading or understanding English, you may want to consider taking an English language course or using resources such as online translators to help you prepare for the test.
It's important to note that there may be a fee for each attempt at the written test, so it's best to study and prepare thoroughly before taking the test. You can use study guides and practice tests to help you prepare, and some CDL training schools may also offer test preparation courses.

The Louisiana CDL manual is a valuable resource that covers all the topics that will be on the written test, and it's recommended that you review it thoroughly.
Once you pass the written test, you will be eligible to take the skills test, which involves driving a commercial vehicle under the supervision of an examiner. Passing both tests is required to obtain a Class A CDL in Louisiana.
