This endorsement is required to haul any liquid or gaseous materials in a tank or tanks having a capacity of 1,000 gallons or more that is either permanently or temporarily attached to the vehicle or chassis. To receive this endorsement, applicants must pass a test. The test consists of 20 multiple choice questions. Each question has three or four possible answer choices. To pass, the applicant must answer at least 16 questions correctly. Test questions come from the North Carolina Commercial Driver License Manual. Questions come from chapters covering: Driving Safely, Tank Vehicles, Hazardous Materials and Combination Vehicles. The Tank endorsement can be used with the Class A, B or C CDL.
1. Which of the following is not a good way to reduce crashes when turning right?
When making a right turn, avoid turning too wide to the left. If you must swing into another lane to complete the turn, you should keep the rear of your vehicle close to the curb. Leaving space to the right of your vehicle while turning right may indicate to other drivers that you are turning left, so they may attempt to pass you on your right.
2. If using a helper while backing a vehicle, where should they stand?
If you use a helper while backing your vehicle, they should stand near the back of the vehicle in a place where they are visible to you. Before backing, work out a set of hand signals that both you and your helper understand. Agree on a signal for "stop."
3. ____ is a thin layer of ice that forms on road surfaces.
Black ice is a thin layer of ice that is clear enough for the road surface to be seen through it. A road covered in black ice may look like it is merely wet. You should be very careful when temperatures are below freezing and the road looks wet.
4. The ____ trailer is the most likely to turn over if a driver takes a turn too quickly.
When making a turn, be sure to steer gently and smoothly. Making a quick turn while pulling trailers is dangerous and can increase the risk of the last trailer rolling over.
5. What is a retarder?
Retarders help to slow vehicles, reducing drivers' need to use brakes.
6. The trailer hand valve should be used:
The trailer hand valve (also referred to as the "trolley valve" or "Johnson bar") works the trailer brakes and should be used only when testing them. Using the trailer hand valve while driving could result in a skid.
7. Broken suspension parts:
The suspension system is responsible for supporting a vehicle, supporting its load, and keeping its axles in place. When inspecting your vehicle, check for damaged or missing spring hangers, spring leaves, shock absorbers, u-bolts, and frame members. Broken parts in the suspension system are extremely dangerous.

It's important to note that the Tank endorsement skills test is in addition to the basic CDL skills test that is required for all CDL applicants. You will need to pass both tests in order to obtain your CDL with a Tank endorsement in North Carolina.
1. Tank vehicle type: If you obtain a CDL with a Tank endorsement, you are only permitted to drive tank vehicles that fall within the category of the endorsement. For example, if you have a Tank endorsement for liquids, you cannot drive a tank vehicle that transports gases.
2. Cargo type: You are only permitted to transport the types of cargo that your Tank endorsement covers. For example, if you have a Tank endorsement for flammable liquids, you cannot transport non-flammable liquids.
3. Endorsement expiration: Your Tank endorsement will expire at the same time as your CDL. You will need to renew your CDL and Tank endorsement on a regular basis.
4. Special training requirements: To transport certain types of hazardous materials, you may need to undergo additional training and certification beyond what is required for your Tank endorsement.
It is important to understand these restrictions and limitations if you hold a CDL with a Tank endorsement in North Carolina. Violating these rules can result in fines, loss of your CDL, or even criminal charges in some cases.
If you are caught transporting liquid or gas materials without a CDL Tank endorsement, you could face fines, penalties, and even the suspension or revocation of your regular CDL. Additionally, if you are transporting hazardous materials without the proper endorsements and safety training, you could be putting yourself and others on the road in danger.
It's always best to make sure you have the proper endorsements and training before operating any commercial motor vehicle that requires special skills or knowledge.
To add the Tank endorsement to your CDL, you must first pass the Tank endorsement knowledge test at a North Carolina DMV office. The test covers topics such as safe driving practices, inspection of tank vehicles, and special precautions for transporting hazardous materials. You may need to provide additional documentation, such as a hazardous materials endorsement or proof of training, depending on the type of cargo you will be transporting.
Once you have passed the knowledge test, you may need to take a skills test to demonstrate your ability to safely operate a tank vehicle. The skills test may involve driving on public roads or in a controlled environment.
After passing the knowledge and skills tests, the Tank endorsement will be added to your existing CDL license, along with any other applicable endorsements you may have.
It's important to note that adding endorsements to your CDL may require additional fees and paperwork. Be sure to check with your local DMV office for specific requirements and instructions.
