The Class B CDL (Commercial Driver's License) skills test is designed to assess your ability to safely operate a commercial vehicle of Class B weight rating. The skills test has three parts: a pre-trip inspection, a basic vehicle control test, and an on-road driving test. Here is an overview of each part:

1. Pre-trip inspection: You will be required to perform a thorough inspection of your vehicle to ensure that it is safe to operate. You will need to demonstrate your ability to identify and explain the function of various components of the vehicle, such as brakes, lights, tires, steering, and suspension.

2. Basic vehicle control test: You will be asked to perform several maneuvers in a controlled environment, such as backing up, turning, shifting gears, and stopping. The examiner will assess your ability to safely control the vehicle and follow proper procedures.

3. On-road driving test: You will be required to demonstrate your ability to safely operate the vehicle on public roads. The examiner will give you directions and evaluate your ability to follow traffic laws, make proper lane changes, use mirrors effectively, and communicate with other drivers.

It's important to note that passing the skills test alone is not enough to obtain a Class B CDL license in Michigan. You must also pass a written knowledge test and meet other requirements, such as medical certification and background checks. It's recommended that you study the Michigan CDL manual thoroughly and practice driving with a licensed commercial driver before taking the skills test.

The interpreter must be at least 18 years old and fluent in both English and your chosen language. They will be required to sign an oath of confidentiality and sit with you during the test.

It's important to note that while taking the written test in your native language can be helpful, it's still important to have a good understanding of English as well.

To request accommodations for the Class B CDL written test, you will need to complete an Accommodation Request Form and submit it to the Michigan Secretary of State's office at least 30 days before your scheduled test date. The form requires documentation from a qualified professional (such as a doctor or psychologist) that verifies your disability and explains the specific accommodations you need.

It's important to note that the Michigan Secretary of State's office will make every effort to provide reasonable accommodations, but not all requests may be granted. If you have any questions about the accommodation request process, you can contact the Michigan Secretary of State's Office of Services to the Blind and Visually Impaired at 1-800-292-4200.

If you fail the Class B CDL (Commercial Driver's License) written test in Michigan, you can retake the test. The Michigan Secretary of State's office allows you to retake the written test as many times as necessary, but you will need to pay the testing fee each time you take the test.

This can be helpful in identifying areas where you need to improve your knowledge before taking the test again. You will also be required to wait at least one business day before retaking the test.

It's important to note that if you fail the written test three times, you will need to wait at least two weeks before taking it again. Additionally, if you fail the same test three times, you will be required to retake a driver education course before being allowed to take the test again.

To prepare for the written test, it's recommended that you study the Michigan Commercial Driver License Manual, which is available online or at any Michigan Secretary of State branch office.
