At Fundamental Labor Strategies, we have several driving jobs available that require CDL endorsements. CDL endorsements give truck drivers the ability to operate certain types of commercial vehicles, such as doubles, tankers, passenger buses, or hazardous material carriers.

How to get a CDL endorsement?
You must pass additional tests to obtain endorsements for your CDL. Some of these endorsements require a knowledge test, skills test, or both. Once passed, the endorsement allows the CDL holder to operate that specific type of vehicle.

Can I add endorsements to my CDL later?
CDL endorsements are able to be added to your commercial driver’s permit or added on to your license after the fact. Whichever method you end up taking to add these endorsements to your CDL, they all require an additional fee and tests.

What are the types of CDL endorsements?

  • T – Double/Triple Trailers – This allows the driver to operate a tractor with double or triple trailers. (Require knowledge test only).
  • N – Tank vehicle – This allows the driver to operate a tank vehicle (permanent or temporary tank). (Require knowledge test only).
  • H – Hazardous materials – This allows drivers to operate vehicles that transport hazardous materials, such as flammable and combustible liquids, gases, or other explosives. This endorsement requires a security check. (Require knowledge test only).
  • X – Combination of tank and hazardous materials – This allows the driver to operate tank commercial vehicles that transport hazardous materials. This endorsement requires a security check. (Require knowledge test only).
  • S – School Bus – This allows the driver to operate a school bus. (Require knowledge and skills test).
  • P – Passenger – This endorsement allows drivers to operate a vehicle that carries a specified number of passengers. (Require knowledge and skills test).

What endorsements are allowed on a Commercial Learner’s Permit (CPL)?
Commercial learner’s permits (CLP) may only carry “P”, “S”, and “N” endorsements.

Hazardous materials (H or X) endorsements are not allowed on a CLP because they require full CDL and federal security clearance.

Do CDL endorsements expire?
Yes – CDL endorsements expire with your Commercial Driver’s License, and in many cases, you will need to retake the corresponding test.

The “H” or “X” endorsements will expire no more than 5 years after the date the security assessment was completed.

Having CDL endorsements allows a driver to have more career flexibility. Obtaining endorsements will qualify you for more types of trucking jobs and oftentimes for higher paying positions.
