3. On-Road Driving: You will be asked to drive the vehicle on public roads while demonstrating your ability to safely operate the vehicle and obey traffic laws.

No, the Class A CDL written test in Missouri is currently only available in English. The Missouri Department of Revenue requires that all applicants be able to read and understand English in order to pass the written test. This is because the test questions and answers are only available in English and all road signs and traffic signals are also in English.
However, if you have difficulty reading or understanding English, you may be able to use an interpreter for the written test. You must provide your own interpreter and they must be fluent in both English and your preferred language. The interpreter must also sign an affidavit stating that they will accurately translate the test questions and answers.
It's important to note that if you use an interpreter for the written test, you will be required to take the driving skills test with a State Trooper who speaks English, as there are no interpreters allowed during the on-road portion of the CDL skills test.
Yes, you can request accommodations for the Class A CDL written test in Missouri if you have a disability that may prevent you from taking the test under standard conditions. The Missouri Department of Revenue provides reasonable accommodations to ensure access to testing for individuals with disabilities under the Americans with Disabilities Act (ADA).
To request accommodations, you must submit a written request to the Missouri Department of Revenue's Driver License Bureau at least 30 days before your scheduled test date. The request must include documentation of your disability and a description of the specific accommodations you require.
Examples of accommodations that may be available include extended testing time, a separate testing room, or the use of assistive technology such as screen readers or magnifiers.
Once your request has been received and reviewed by the Missouri Department of Revenue, they will contact you to discuss your accommodations and make arrangements for your test. It's important to note that not all requests for accommodations may be granted, and reasonable alternatives may be suggested if the requested accommodation is not feasible.
If you fail the Class A CDL written test in Missouri, you are allowed to retake the test. However, you must wait at least one day before taking it again. If you fail the test three times, you will be required to wait at least 7 days before taking it again.
Each time you take the written test, you will be charged a fee. Therefore, it's important to adequately prepare for the test to increase your chances of passing on your first attempt. You can find study materials, including the Missouri Commercial Driver License Manual, on the Missouri Department of Revenue's website.
If you fail the test multiple times or are having difficulty passing it, you may want to consider enrolling in a commercial driver's license training program. These programs can provide additional instruction and practice to help you pass the written test and prepare for the skills test.
