How long is the Doubles and Triples ELDT course?

The T endorsement curriculum is focused on what's specifically different about pulling multiple trailers — coupling and uncoupling multiple trailers in sequence, handling double and triple combinations through turns and on highway grades, managing the unique stability challenges of long combinations, inspection routines for multi-trailer setups, and the federal regulations on routes and weights. Most students finish in 8 to 12 hours. The course is short because you're already a Class A driver — you've already learned the broader CDL theory.

The compressed timeline relative to base ELDT courses reflects the focused nature of endorsement-specific content. T doesn't re-cover general CDL theory, traffic law, or single-trailer operation — those are prerequisites that the candidate already mastered to earn the underlying Class A. The endorsement curriculum builds directly on that foundation rather than duplicating it, which is why the time investment is dramatically smaller than a full Class A ELDT and the content density is higher per hour of study.

For drivers timing the T endorsement around an employment start date or a job offer, the short timeline means the endorsement rarely becomes the gating constraint. Most drivers can complete T theory in evening sessions over a single week without taking time off work. The actual gate is usually the BTW component plus skills test scheduling at the DMV rather than the theory hours themselves. Drivers should still target the longer end of the time range when first-time exposure to multi-trailer concepts is involved, because rushing the unique-handling content can leave gaps that show up later in the BTW phase.
