What is CDL X Endorsement?


1. What is CDL X Endorsement?

In general, CDL X Endorsement is one of 6 CDL Endorsements types, which is the combination of CDL HazMat (N endorsement) and CDL Tanker (X Endorsement). It seems understandable because a Tanker usually transports and carries hazardous materials, thus owning the combo CDL endorsement is a must for Tank drivers. However, because this is a combination endorsement, the process to obtain is a little bit more complicated than other endorsements. Let’s move to the second part to know how to get an X endorsement.


2. What is the process of getting a CDL X Endorsement?


Step 1: Submit the application 

  • Call 1-800-777-0133 between 8:00 a.m. and 5:00 p.m. to schedule a skill test appointment. 
  • Mondays, Tuesdays, Thursdays, and Fridays, as well as Wednesdays from 9:00 a.m. to 5:00 p.m., except holidays.
  • Bring the vehicle(s) you will be driving for the class.
  • The skills exam must be passed. Road testing, basic control skills tests, and vehicle inspection are all included. If you fail any section of the skills test, you will have to retake it. You only have three chances to pass the skills exam. Each time you retake the skills exam, you must pay a retest charge.

In the following cases, the skills test requirement may be waived:

  • You currently hold a valid CDL from another state, or your CDL has been expired for less than two years. You must forfeit that license or (proof thereof).
  • Check that the license has the same classification, endorsements, and limits as the one you’re seeking for.
  • If you have military driving experience, please submit a completed Commercial Military Waiver (DL 965) (PDF).


Step 2: Complete all appropriate law tests

Generally, in order to obtain an X endorsement, you must pass the Tanker endorsement Knowledge Test and Hazmat Knowledge Test. Besides, the TSA Background check is a must for drivers. You may need to read the CDL Tanker Endorsement Study Guide as well as the CDL Hazmat Endorsement Study Guide to understand clearly what you will be tested.  Averagely, it takes you between 2 and 6 weeks to complete your background check. 


Step 3: Submit a medical form

You must provide a CDL Self-certification Form that examines by a certified medical examiner in order to prove that you are qualified for this X endorsement. For instance, this is a medical form to illustrate. 


Step 4: Submit your fingerprints

To prove your identity, you will be required to get your fingerprints. 


Step 5: Pay the fee

The cost of CDL X Endorsement varies among states. The total cost of obtaining a CDL Hazmat endorsement is about $100. The TSA screening is $86.50, and certain states may charge additional fees to take the exam and renew your CDL-A license. If you drive more than 2,500 miles each week, you’ll recoup your investment in 2-4 weeks. That depends on how much more money you get.


Step 6: Submit other required information 

To be qualified to apply for a CDL with the X endorsement, you must meet the following rules:

  • Must be at least 18 years old
