What is tanker endorsement, and why do you need it?

You’ve come to the right place for answers.

I wrote this guide discussing everything you need to know about tanker endorsements and if there are differences in liquid or gaseous materials requirements.

I’ll also give you some tips on the tanker endorsement knowledge test and what it takes to become a tanker truck driver.

What Is Tanker Endorsement?

A tanker endorsement is also known as an N endorsement. It’s a tanker certification and a commercial driver’s license (CDL) showing that you can transport liquid and gas in bulk.

For liquid or gaseous freight, you need both endorsements to operate.

Having an N endorsement widens your tank vehicle options.

What About Other Tanker Endorsements?

Aside from the N endorsement, you can also apply for an X endorsement, considered a hazmat endorsement, which allows you to haul hazardous materials.

With the N and X tanker endorsements, you’re qualified for hauling liquids, gas, and hazardous materials combined.

What Is a CDL Tanker Endorsement?

A CDL endorsement is the most basic tank vehicle endorsement in the trucking industry. You need a tanker endorsement on top of your CDL truck driver license to earn more and drive tank vehicles with more versatile cargo.

The trucking industry requires specialized endorsements like hazmat for hazardous liquids and other specific deliveries. However, all tanker vehicles require you to have a CDL and go through proper training.

How To Get Tanker Endorsement

You must take and pass the tanker endorsement knowledge test for the N endorsement.

This test includes 25 multiple-choice questions, and it only allows five mistakes. You can buy a reviewer for the standard test.

This is not a free test; you must pay a test fee (depending on your state).

You must also take the endorsement knowledge test for the X endorsement. After that, take the hazmat knowledge test and pass the Transportation Safety Administration (TSA) background check.

Unlike the basic endorsement knowledge test, completing the additional requirements for the X endorsement takes up to six weeks.

You must take the Entry-Level Driver Training test in certain places like Escambia County, Florida. You’ll get 30 days to complete your background check and fingerprints if successful.

If you haven’t finished the requirements within 30 days of taking the hazmat endorsements exam, you need to take the written exam again.

What Are Tanker Endorsement Requirements?

The N and X endorsement certificates have the following requirements.

  • You must be at least 18 years old.

  • You must have a valid United States passport and a valid residential status.

  • You must pass the eye exam.

How Much Does a Tanker Endorsement Cost?

The prices of an N and X endorsement differ depending on State.

Here’s an estimate of how much it’ll cost (These estimates are based on Escambia County, Florida.).

  • CDL: $81.25

  • Endorsements: $7 each (You’ll need separate endorsements for a tanker, double triple, passenger, school bus, and motorcycle).

  • Background Check and Fingerprints: $91

Besides the written test and training fees, you must also consider the time and effort you spend studying.

If you need an endorsement and plan to transport liquids and other haul loads but can’t study alone, consider enrolling in truck driving schools.

Note: These schools know the standard endorsement requirements, but you must pay enrollment costs.

When Do You Need a Tanker Endorsement?

When Do You Need a Tanker Endorsement

Are there any tanker endorsement exceptions? If your total combined volume and weight don’t meet the requirements and you aren’t driving a commercial vehicle, you won’t need an endorsement.

Here are vehicles that require an endorsement.

  1. If the vehicles with liquid or gas within one or more tanks have a capacity of 119 gallons each.

  2. If a commercial motor vehicle has an attachment of liquid or gas of at least 1,000 gallons or more.

If you transport liquid loads, even water, that exceeds 1,000 gallons, you need an endorsement.

What Is the Difference Between a Hazmat and Tanker Endorsement?

What Is the Difference Between a Hazmat and Tanker Endorsement

The hazmat endorsement is a specialized endorsement needed for a driver hauling hazardous materials.

You should have an endorsement if you want to haul liquids or gas and if you’re hauling over 1,000 gallons and your vehicle freights have a capacity of over 119 gallons each.

How Tanker Endorsements Affect Shipping Prices

Besides the monetary investment, you’ll spend time and effort learning and preparing for the exams.

Truckers who possess tanker endorsements can charge more.

A truck driver without these endorsements can deliver basic goods that aren’t incredibly dangerous or in large quantities.

Some companies must get an endorsed truck driver depending on the freight’s requirements. If those drivers are rare, companies have no choice but to pay more for certified drivers.
