Are you planning on driving a tanker truck that transports hazardous materials?
Then you’ll have to add the X endorsement to your commercial driver’s license (CDL).
But what is an X – hazmat and tanker endorsement?
When is it required?
How do you get it?
We’re here to answer all those questions and more.
So let’s jump right to it!
What is a Hazmat and Tanker Endorsement?
The X endorsement allows commercial drivers to operate a tanker truck that transports hazardous materials.
This is a combination endorsement.
So instead of getting an individual N endorsement (for tanker trucks) and an H endorsement (for hazardous materials), you only need to apply for the X endorsement.
Okay, you won’t have to get 2 separate endorsements anymore.
However, you still have to learn about both and go through the same application process.
When is a Hazmat and Tanker Endorsement Required?
Tanks usually carry hazardous materials — so it’s more likely that you’ll need the X endorsement if you drive a tanker truck.
But there are a few specifications that you need to know about.
- You only need the X endorsement if:
- The tank transports hazardous materials, such as those that are toxic, flammable, and can potentially cause harm.
- The tank contains individual liquid or gaseous containers greater than 119 gallons.
- The tank and/or containers are loaded and not empty.
- The total combined volume of the liquid or gaseous materials being hauled is greater than 1,000 gallons.
- You only use the X endorsement for:
- Non-excepted interstate (NI) driving
- Non-excepted intrastate (NA) driving
IMPORTANT! Every state has different rules and regulations, so make sure to check the specifics of where you live.
