But how can you get this certification?

This post will address all your concerns related to CDL tanker endorsement. We will explain everything you need to know, from understanding what CDL tanker endorsement is, to how to fulfill the qualifications, and how you can get it. Scroll down for more details!

What is a CDL tanker endorsement?

A CDL tanker endorsement which is well known as an N endorsement, grants permission to carry large amounts of liquid and gaseous products. These can include non-hazardous materials such as water, food-grade liquids (like milk or juice), or hazardous materials that include fuel and chemicals.

The reason N endorsement is required for tanker trucks is that there are particular challenges in the transporting of liquid cargo. Unlike solid cargo, liquids slosh around inside the tank while the truck is on the road, moving from side to side with each curve or brake applied. This movement affects the balance of the vehicle, making it particularly difficult to handle, especially when the tank is only partially filled. Therefore, the Federal Motor Carrier Safety Administration (FMCSA) requires any driver who intends to haul bulk liquids to get a tanker endorsement to ensure they understand such dynamics and how to handle them safely.

When do you need a tanker endorsement?

According to the FMCSA, a tanker endorsement is required if the vehicle you are operating meets the following criteria:

  • Cargo being transported consists of liquid or gas containers with a capacity greater than 119 gallons.
  • The aggregate combined rated capacity of all liquid or gas containers is greater than 1,000 gallons.
  • The containers are loaded and transported.

These rules apply to semi-trailers carrying liquids in a tanker, as well as dry vans pulling large containers, for example, Intermediate bulk containers (IBCs) individually containing over 119 gallons.

In addition, you are required to get a CDL tanker endorsement if you are a driver in the following industries:

  • Oil and gas industry: Drivers transport gasoline, diesel, and other fuels to fill up at gas stations or within a distribution facility.
  • Dairy and beverage industry: Drivers haul milk, juices, and any other liquids from manufacturing plants to retailers or storage facilities.
  • Chemical industry: Drivers transport liquid chemicals, solvents, or other hazardous materials.
  • Agriculture: Truckers haul liquid fertilizers, pesticides, or irrigation water.
  • Waste disposal: Drivers operate the transportation of liquid waste, sewage, or any other bu-product resulting from it.
  • Fire department: Water tankers transport large quantities of water pending the need in case of an emergency.
  • Construction: Liquid cement transporters or any other type of liquid that is required to be carried out in construction projects.

How to get tanker endorsement on CDL?

Follow this step-by-step guide to navigating your process of obtaining a CDL tanker endorsement:

Step 1: Confirm your ability

Ensure you meet the above eligibility requirements about the age minimum and residence status.

Step 2. Review your CDL

Before applying for a CDL tanker, you must first hold a valid Class A or Class B CDL. Schedule time to get one of these licenses if you do not already have one.

Step 3: Schedule an appointment at DMV

You must visit your local DMV to apply for the tanker endorsement and take the knowledge test. It is recommended that you call the DMV in your state to make an appointment to avoid long waiting periods. Remember to bring along: your current CDL, proof of citizenship or legal residency, and any documents required by your state, such as insurance information.

Step 4. Take the knowledge test

You will take this test at your state’s DMV. The tanker endorsement test covers the areas of surge effect, safety driving practices, emergence procedures, and loading and unloading procedures. You must answer 80% of the total questions correctly to pass the exam. Many states allow you to retake the test if you do not pass the exam on your first try, but require certain waiting.

Step 5. Pay the necessary fees

Application fees and testing for endorsements in most states range from $10 to $50.

Step 6. Consider combining endorsements

If you want to transport hazardous liquids such as gasoline or propane, you will be required to have both a Hazardous materials (HazMat) endorsement and a tanker endorsement. It is a good choice to apply for the X endorsement, which covers both. This endorsement can save you time and effort when desiring to transport dangerous materials in liquid form. To obtain an X endorsement, you need to:

  • Pass a HazMat knowledge test
  • Take a TSA background check
  • Submit fingerprints and provide additional documentation for security clearance.

Step 7. Receive your endorsement

Once you have passed the test and paid all required fees, your tanker endorsement will be added to your CDL

Step 8. Keep up to date

The tanker endorsements also can expire and regulations may change over time. Therefore, keep up to date with any changes through DMV notices or industry blogs.
