CDL endorsements and credentials: what to tell your recruiter
Understand the difference between license endorsements, restrictions, and separate credentials.
By RoadHouse Recruiting · Reviewed October 3, 2026
Read your current license
Report the endorsements and restrictions you hold today. Tell your recruiter if you plan to add a credential, but distinguish that plan from an endorsement already issued. Equipment experience is separate: driving a reefer or flatbed does not itself establish a CDL endorsement.
Know the common endorsement codes
T covers double/triple trailers; N covers tank vehicles; H covers hazardous materials; X combines tank and hazardous-materials endorsements. The required endorsement depends on the vehicle and cargo. Check the specific opening with the carrier and consult your state licensing agency for testing and eligibility requirements.
Keep separate credentials separate
A TWIC card and passport are separate credentials, not CDL endorsements. Share whether you currently hold them when an opportunity involves port access or international travel. Ask what the actual route requires before paying for a new credential.
Discuss restrictions and experience
Let your recruiter know if your license has an automatic-transmission restriction. Also describe recent equipment experience, how long you drove each type, and whether you need additional training. A credential alone does not guarantee that you meet a carrier’s experience requirements.
Choose training around a real goal
Ask which opportunities a new endorsement could make relevant to you, whether the carrier offers training support, and whether it changes the duties or pay. Confirm current requirements with official sources before enrolling.
