In Massachusetts, the CDL written test is available in English and Spanish. Additionally, you may be able to request an interpreter for other languages. It's important to check with your local DMV or licensing agency to see what options are available and what requirements you need to meet.
If you do choose to take the test in a language other than English, it's important to note that you will still need to be proficient in English when it comes to operating a commercial vehicle. You will need to be able to read and understand road signs and communicate with law enforcement officers and other drivers on the road.
It's also important to note that some states may require you to provide your own interpreter or pay for interpreter services if they are not provided by the state. Make sure that you understand all of the requirements and costs associated with taking the CDL written test in a language other than English before you begin the process.

2. Use of a reader or magnifying device
3. Use of a scribe or assistive technology, such as voice recognition software, for individuals with mobility or dexterity impairments

The specific waiting period and number of times you can retake the test will vary depending on your state's policies. It's important to note that some states may require you to pay an additional fee for each attempt at the written test.
If you fail the written test multiple times, you may be required to complete additional training or education before being allowed to retake the test.

You will also need to pass a skills test and meet other requirements before being issued a CDL. If you are struggling with any aspect of the process, consider seeking out additional resources or training to help you succeed.
