To obtain any of these endorsements, you must pass additional written knowledge tests and in some cases, additional skills tests. It's important to note that some employers may require additional endorsements or qualifications beyond the minimum state and federal requirements.
1. Pre-trip Inspection: You will be required to perform a pre-trip inspection of your vehicle to ensure that it is safe and in proper working order. This includes checking the vehicle's engine compartment, cab, brakes, tires, lights, and other critical components.
2. Basic Vehicle Control: You will be required to demonstrate your ability to control the vehicle in various situations such as backing up, turning, shifting gears, and parking. This test is usually conducted in a controlled environment such as a driving range.
3. Road Test: You will be required to demonstrate your ability to operate the vehicle safely and effectively on the road. This includes driving in traffic, making turns, changing lanes, navigating intersections, and responding to various road conditions.
During the skills test, you will be evaluated on your ability to perform these tasks safely and effectively according to state and federal regulations. It's important to note that the skills test must be taken in a vehicle that is representative of the type of vehicle you plan to operate with your Class B CDL license.

5. Interstate vs. intrastate commerce: Depending on the type of commerce you plan to engage in (interstate or intrastate), there may be additional restrictions or requirements that apply to your Class B CDL license.
It's important to note that these restrictions and limitations are in place to ensure the safety of both the driver and others on the road. Violating these restrictions can result in fines, penalties, and even the suspension or revocation of your CDL license.
To take the written test in a language other than English, you must indicate your preferred language when you apply for your CDL permit. You will then be given a copy of the CDL manual in your preferred language to study for the test. When you are ready to take the test, you will need to schedule an appointment at a DMV office that offers the test in your preferred language.
It's important to note that even if you take the written test in a language other than English, you will still need to have a good understanding of English to operate a commercial vehicle safely. This is because many road signs and other critical information related to driving are presented in English in the United States.
To request accommodations, you will need to fill out a Request for Reasonable Accommodation form and submit it to the DMV along with documentation that supports your request. Examples of accommodations that may be provided include:
1. Extended time to complete the test
2. A reader or sign language interpreter
3. A separate testing room
4. A large-print or Braille CDL manual
5. Use of a computer or other assistive technology
The DMV will review your request and let you know if your accommodation request has been approved. It's important to note that you must make your request for accommodations in advance of your scheduled test date to allow time for the DMV to make the necessary arrangements.
If you have any questions or concerns about requesting accommodations for the CDL test, you can contact the Rhode Island DMV's Customer Service Center for assistance.
It's important to note that you are only allowed a certain number of attempts to pass the written test before you will need to start the application process over again. In Rhode Island, if you fail the written test three times, you will need to begin the entire CDL application process again, which includes submitting a new application, providing documentation, and paying all applicable fees.
To increase your chances of passing the written test on your first attempt, it's important to study and review the CDL manual thoroughly. You can also take practice tests online or through a CDL training program to help prepare for the exam.
