It's important to note that if you are applying for a hazardous materials (HAZMAT) endorsement in addition to your Tank endorsement, you'll need to complete additional steps and meet additional requirements.
1. Age: You must be at least 21 years old to operate a commercial vehicle across state lines or transport hazardous materials.
2. CDL: You must already have a valid California Commercial Driver's License (CDL) or be applying for one at the same time you apply for the Tank endorsement.
3. Knowledge Test: You must pass a written knowledge test on tanker vehicles. The test will cover topics such as loading and unloading, vehicle inspection, driving hazards, and emergency procedures.
4. Skills Test: You must pass a Tanker Skills Test in a tanker vehicle or complete an approved training course. During the skills test, you will be evaluated on your ability to safely operate a tanker vehicle and perform tasks such as backing up, turning, and maneuvering in tight spaces.
5. Medical Requirements: You must meet the medical requirements for operating commercial vehicles as set forth by the Federal Motor Carrier Safety Administration (FMCSA).
6. Background Check: You must pass a Transportation Security Administration (TSA) background check if you are also applying for a hazardous materials (HAZMAT) endorsement.
7. Fees: You must pay the appropriate fees for both the CDL and Tank endorsement.
It's important to note that obtaining a Tank endorsement is an additional requirement for those who plan to transport liquids or gases in bulk tanks. The Tank endorsement is not required for drivers who only transport smaller quantities of hazardous materials that do not require placarding.
You can receive training from a commercial driving school or from an employer-sponsored training program. The training should include classroom instruction on the characteristics of tanker vehicles and hands-on experience with driving and operating a tanker vehicle. Some employers may also require additional training specific to their company policies and procedures.
If you choose not to receive formal training, you can still pass the Tank endorsement test by studying the CDL handbook and practicing on your own. However, this approach may not fully prepare you for the unique challenges of driving a tanker vehicle, and it may be more difficult to find employment without formal training or experience.
The Tank endorsement knowledge test covers topics related to the safe operation of tanker vehicles, such as:
- Tanker vehicle inspection
- Proper loading and unloading procedures
- Identifying hazards and emergencies
- Controlling liquid surge and sloshing
- Safe driving practices
You can prepare for the Tank endorsement knowledge test by studying the California Commercial Driver Handbook. The handbook includes a section on tanker vehicles, which provides detailed information on the topics covered in the test.
It's important to note that passing the Tank endorsement knowledge test is just one part of obtaining a CDL Tank endorsement. You will also need to pass a skills test, which involves demonstrating your ability to safely operate a tanker vehicle and perform tasks such as backing up, turning, and maneuvering in tight spaces.
1. Tanker Vehicle Inspection: You will be tested on your ability to inspect the tanker vehicle for leaks, defects, and other safety hazards. You should also know how to check for proper securement of any equipment and cargo that is being transported.
2. Safe Driving Practices: This section of the test evaluates your knowledge of safe driving practices while operating a tanker vehicle. You should be able to demonstrate your ability to maintain control of the vehicle, anticipate and respond to potential hazards, and adjust your driving based on weather and road conditions.
3. Cargo Loading and Unloading: You will be tested on your knowledge of proper procedures for loading and unloading liquids, including how to properly balance the weight of the load in the tank.
4. Hazardous Materials: If you are transporting hazardous materials, you will need to demonstrate your knowledge of specific regulations related to hazardous materials, including placarding requirements, emergency procedures, and proper handling and storage.
5. Liquid Surge and Sloshing: Tanker vehicles are prone to liquid surge and sloshing, which can affect vehicle stability and handling. You will need to demonstrate your understanding of how to control liquid surge and sloshing in order to maintain vehicle stability.
It's important to study all these topics thoroughly before taking the written test for a Tank endorsement, as it is crucial for safe operation of a tanker vehicle.
During the skills test, you will be asked to perform a series of maneuvers that demonstrate your ability to control the vehicle, including:
1. Pre-trip Inspection: You will be required to perform a pre-trip inspection of the tanker vehicle before you begin driving. This involves checking the vehicle's brakes, tires, lights, and other equipment for safety and compliance.
2. Straight Line Backing: You will be asked to back up the tanker vehicle in a straight line for a certain distance. This is designed to evaluate your ability to control the vehicle's steering and braking systems.
3. Offset Backing: You will be asked to back up the tanker vehicle into a designated parking space at an angle. This is designed to evaluate your ability to maneuver the vehicle in tight spaces.
4. Parallel Parking: You will be asked to parallel park the tanker vehicle between two cones. This is another maneuver that tests your ability to control the vehicle's steering and braking systems.
5. Emergency Maneuvers: You may also be asked to demonstrate your ability to respond to emergency situations, such as sudden stops or swerves.
It's important to practice these maneuvers before taking the skills test for a Tank endorsement, as they require specific skills and knowledge in order to perform them safely and effectively.
1. Endorsement Required: A Tank endorsement is required to operate a tanker vehicle that is designed to transport liquids or gases.
2. Type of Tanker Vehicle: The endorsement is specific to the type of tanker vehicle that you will be operating. For example, if you have a Tank endorsement for a liquid tanker, you cannot operate a gas tanker without obtaining an additional endorsement.
3. Endorsement Renewal: The Tank endorsement must be renewed every 5 years.
4. Age Limit: Drivers under the age of 21 are not allowed to transport hazardous materials, which includes liquids and gases.

It's important to obtain the proper endorsement and comply with all safety regulations to prevent accidents and protect yourself and others on the road.
To add the Tank endorsement to your CDL license, you must first obtain a Commercial Learner's Permit (CLP) and pass the CDL Tank Vehicle written test. Once you have passed the written test, you will need to take a Tank Vehicle Skills Test in a vehicle that meets the endorsement requirements.
If you pass both tests, the DMV will add the Tank endorsement to your CDL license. You will receive a new license with the Tank endorsement added.
It's important to note that you must have a valid CDL license before applying for the Tank endorsement, and you must meet all other requirements for obtaining a CDL in California.
Some of the requirements and regulations for handling hazardous materials with a CDL Tank endorsement include:
1. Special training: Drivers who transport hazardous materials must receive special training on handling and transporting these materials safely.
2. Proper labeling and placarding: Hazardous materials must be properly labeled and placarded according to federal regulations.
3. Vehicle inspections: Drivers must complete a pre-trip inspection of their vehicle before each trip to ensure that it is safe to transport hazardous materials.
