If you’re looking to expand your hauling options and boost your income, adding a doubles and triples endorsement to your CDL might be the move. This endorsement lets you pull longer combination vehicles (LCVs), giving you access to higher-paying loads and specialized routes. In this post, we’ll break down what the endorsement covers, how to get it, and what it means for your job prospects.

What Is a Doubles and Triples Endorsement? A doubles and triples endorsement (also called a T endorsement) allows a CDL holder to pull:

  • Double trailers (two trailers hitched together)
  • Triple trailers (three shorter trailers in sequence)

These longer combinations are common in LTL (less-than-truckload) and high-volume freight networks. They’re usually found on major highways and require careful handling due to their length and potential for trailer sway.

Why Drivers Get This Endorsement Adding a doubles and triples endorsement can give you a competitive edge:

  • Higher Pay: LCV loads often pay more due to the complexity and responsibility.
  • More Job Options: Especially with LTL carriers like FedEx, UPS, and XPO.
  • Career Flexibility: Adds another layer of qualifications to your driving resume.

Pros, Cons & What to Watch Out For Pros:

  • Increased income potential
  • More diverse freight opportunities
  • Builds professional credibility

Cons:

  • Requires extra training and testing
  • Not every state or region allows triple trailers
  • More challenging driving, especially in wind or on inclines

What It Means for Your Driving Career If you’re currently a solo company driver or even an owner-operator looking to transition to LTL or regional work, this endorsement could open new doors. Some companies require it for specific routes or offer bonuses to drivers who have it. It’s especially useful if you’re thinking about long-term job security with stable carriers.
