T Endorsement in Texas

The Doubles/Triples endorsement authorizes you to tow double or triple trailers. These combination vehicles require specialized knowledge of coupling, uncoupling, handling characteristics, and braking systems unique to multi-trailer configurations. This endorsement is most commonly used by LTL (less-than-truckload) carriers who regularly run double trailers between terminals. In Texas, the T endorsement is particularly valuable due to the state's strong presence in Oil & gas (Permian Basin, Eagle Ford, Gulf Coast) and Cross-border trade (Mexico, multiple ports of entry) industries. Combined with TX's average CDL-A salary of $62,400, the +$3,000 - $8,000/year boost makes this one of the best endorsement investments you can make.
