If you’re reading this, odds are you’re ready to level up your commercial driving career, and answering the riddle of how to get a tanker endorsement on a CDL may be the only thing standing in your way.
Maybe you want to expand your job options, boost your pay, or simply stand out from the sea of CDL holders in the trucking industry. Whatever your reason, adding a tanker endorsement to your CDL is a smart, strategic move, and it’s more doable than you think.
Let’s break it down step-by-step so you know exactly how to get a tanker endorsement on a CDL without spinning your wheels.
What Is a Tanker Endorsement on a CDL?
A CDL tanker endorsement is an official add-on to your commercial driver’s license that allows you to legally haul liquid or gaseous materials in bulk.
We’re talking milk, fuel, chemicals, even water in some cases. This endorsement is also known as the N endorsement and is required if you’re operating a tank vehicle designed to transport liquids with a capacity of 1,000 gallons or more. These tank vehicles are essential to the transport of liquid loads, but they take proper training from the federal motor carrier safety administration to operate.
Keep in mind: if the material you’re hauling is hazardous, you may also need a hazardous materials endorsement on top of your tanker. For any driver wondering how to get a tanker endorsement on a CDL, this is one of the first distinctions you’ll want to clarify.
Who Needs a Tanker Endorsement (and Who Doesn’t)?
If you plan on driving a tank vehicle that hauls bulk liquids or gaseous freight, you’re going to need that N endorsement. This includes:
- Milk haulers
- Fuel truck drivers
- Chemical transporters
- Food-grade liquid drivers
Even some dry freight drivers are surprised to find they need a tanker endorsement when their load includes intermediate bulk containers with liquid cargo.
If your loads are small, sealed, and under the capacity threshold on a commercial vehicle, you’re likely in the clear. But when in doubt? Ask your safety manager or check with your local DMV. It’s always best to understand how to get a tanker endorsement on a CDL before you end up stuck at a weigh station.
Adding this endorsement early in your career helps prevent future compliance issues and opens more doors in the trucking industry. It’s a smart investment whether you’re new or experienced.
Requirements to Get a Tanker Endorsement on a CDL
As of 2022, the FMCSA’s ELDT regulations require specific training standards for certain endorsements. Ready to get this show on the road and figure out what that means for you? Here’s what you need before applying for your tanker endorsement:
- A valid Class A or B CDL
- Must meet age requirements (usually 21+ for interstate driving)
- Pass the tanker endorsement written knowledge test
- Undergo a background check if applying for hazmat too
- Be prepared to pay an endorsement fee
No additional road skills test is required for the tanker endorsement, but you will need to prove your knowledge through a written knowledge exam. It’s a key step in how to get a tanker endorsement on a CDL that many drivers underestimate. CDL drivers looking to get their tanker endorsement should ensure that they are well prepared to pass this written exam, or face the burden of a retake.
