Before loading or unloading a tank with flammable liquids, you should turn off the engine, unless running the engine is necessary to operate a pump. Ground the tank before opening the filling hole and maintain the ground until after closing the filling hole.

The United States Department of Transportation (DOT)’s Emergency Response Guidebook (ERG) lists all hazardous chemicals and their assigned identification numbers.
5. Driving with a cargo of hanging meat in a trailer:
An operator should drive with care when transporting a cargo of hanging meat. Such a load is unstable, both because it has a high center of gravity and because the swinging of the meat can affect the driver's handling of the vehicle.
6. When loading or unloading a tank that is divided by bulkheads, equal weight distribution is:
Some tanks are divided into multiple smaller tanks by bulkheads. When loading or unloading such tanks, pay attention to weight distribution. Be careful not to place too much weight on a single end of the tank.

It is important to check with your employer and state regulations to see if there are any additional requirements or training programs you need to complete before operating a tanker vehicle.
In addition, the Federal Motor Carrier Safety Administration (FMCSA) requires all CDL holders to participate in ongoing training related to safety and compliance with regulations. This includes training related to tanker vehicles if you hold a Tank endorsement on your CDL.

5. Safe driving practices for tanker vehicles
You must pass this written test with a score of at least 80% to obtain your Tank endorsement.
In addition to the Tank endorsement written test, you must also pass a skills test that evaluates your ability to safely operate a tanker vehicle. This skills test will typically be conducted in a tanker vehicle and will assess your ability to perform maneuvers such as turning, backing up, and braking safely while hauling a liquid load.
It is important to note that you must already have a valid CDL before applying for a Tank endorsement, and you must also have a Hazardous Materials (HazMat) endorsement on your CDL before applying for a Tank endorsement.
1. Tanker vehicle inspection: This includes identifying potential hazards and defects that could affect the safe operation of the tanker vehicle, such as leaks, cracks, or other damage.
2. Tanker loading and unloading procedures: This covers proper procedures for loading and unloading liquids or gases into a tanker vehicle, including how to safely handle hazardous materials.
3. Identifying hazardous materials: This includes understanding the different types of hazardous materials that may be transported in a tanker vehicle, as well as how to properly label and handle them.
4. Emergency response procedures: This covers procedures for responding to emergencies such as accidents, spills, or leaks involving a tanker vehicle.
5. Safe driving practices for tanker vehicles: This includes understanding the unique challenges of driving a tanker vehicle, such as the potential for rollovers or loss of control due to shifting loads, and how to drive defensively to prevent accidents.
It is important to study these topics thoroughly before taking the Tank endorsement written test. You can find study materials online or through commercial CDL training programs.
The skills test will typically include the following maneuvers:
1. Pre-trip inspection: You will need to conduct a thorough inspection of the tanker vehicle before driving it, including checking the brakes, lights, tires, and other components.
2. Basic control skills: You will need to demonstrate your ability to control the tanker vehicle in tight spaces and while maneuvering through obstacles such as cones or barrels.
3. On-road driving: You will need to demonstrate your ability to safely operate the tanker vehicle on the road, including making turns, changing lanes, and merging with traffic.
4. Tanker-specific skills: You will also need to demonstrate your ability to safely load and unload liquids or gases into the tanker vehicle, as well as how to handle emergency situations such as leaks or spills.
It is important to practice these maneuvers before taking the CDL Tank endorsement skills test. Commercial CDL training programs can provide hands-on training and practice opportunities that can help you prepare for the skills test.
One of the main restrictions for drivers with a CDL Tank endorsement is the requirement for a hazardous materials endorsement (HME) in addition to the Tank endorsement. This endorsement is required for drivers who transport hazardous materials in quantities that require placards on their vehicle.
Other restrictions that apply to CDL Tank endorsement holders include:
1. Special training requirements: Drivers with a Tank endorsement must complete additional training on the safe operation of tanker vehicles, including how to respond to emergencies such as spills or leaks.
2. Vehicle restrictions: Tanker vehicles may be subject to weight restrictions or other limitations depending on the type of cargo they are carrying.
3. Endorsement renewal requirements: Tank endorsements must be renewed every five years, and drivers may be required to pass additional knowledge or skills tests as part of the renewal process.
It is important for drivers with a CDL Tank endorsement to understand and comply with these restrictions and limitations in order to maintain their safety and the safety of others on the road.
However, if you are transporting non-hazardous liquids or gases in small quantities that do not require placards on your vehicle, you may not need a CDL Tank endorsement. In this case, you would only need a regular commercial driver's license (CDL) with the appropriate class for the weight of your vehicle and cargo.
It is important to check with the Federal Motor Carrier Safety Administration (FMCSA) and your state's Department of Transportation (DOT) to determine the specific requirements for transporting liquids or gases in your area. They can provide guidance on which endorsements or licenses are required based on the type, quantity, and weight of materials you will be transporting.
To add a Tank endorsement to your CDL license, you will need to visit your state's Department of Motor Vehicles (DMV) or licensing agency and complete the following steps:
1. Submit a completed Commercial Driver's License Application.
2. Provide proof of identity and residency.
3. Pass the written test for the Tank Vehicle endorsement.
4. If applicable, pass the skills test for the type of tanker vehicle you will be operating.
5. Pay any applicable fees.
Once you have completed these steps and passed the necessary tests, your CDL license will be updated to include the Tank endorsement. It is important to note that you must also have a Hazardous Materials endorsement (HME) if you plan to transport hazardous materials in quantities that require placards on your vehicle.
1. Training: You must complete a hazardous materials training program that meets the requirements set forth by the Federal Motor Carrier Safety Administration (FMCSA).
2. Endorsement: In addition to the Tank endorsement, you must also have a Hazardous Materials Endorsement (HME) on your CDL license to transport hazardous materials in quantities that require placards on your vehicle.
3. Placarding: You must display the appropriate placards on your vehicle when transporting hazardous materials. The placards must meet specific size and color requirements.
4. Loading and Unloading: You must follow specific procedures when loading and unloading hazardous materials, including proper handling and securing of the cargo.
5. Reporting Incidents: You must report any incidents involving hazardous materials, including spills or leaks, to the appropriate authorities.
6. Record Keeping: You must maintain accurate records of all hazardous materials transported, including the type of material, quantity, and destination.
It is important to note that there may be additional state or federal regulations that apply to transporting hazardous materials with a CDL Tank endorsement. Be sure to check with your state's Department of Transportation (DOT) and the FMCSA for more information on these regulations.
