Doubles Triples Endorsement: Worth Adding?

The doubles triples endorsement lets CDL drivers legally pull two or three trailers at once, mainly in LTL freight networks that use pup trailers. Many drivers wonder if the extra training and test are worth the effort in 2025.

What the Doubles Triples Endorsement Covers

This endorsement adds the T classification to your CDL. It covers combinations like a tractor pulling two 28-foot pups or, in some states, three trailers. You still follow the same hours-of-service rules, but the setup changes how you handle backing, coupling, and weight distribution on the road.

Most carriers that run LTL routes need this skill because freight moves through terminals in smaller loads. Without the endorsement you stay limited to single-trailer work.

How to Add the Endorsement

You need a valid CDL-A, pass a written knowledge test at the DMV, and complete a skills test that includes coupling and uncoupling doubles. Some training schools bundle the prep in a one- or two-day course for a few hundred dollars. Current drivers often study on their own and test during a scheduled day off.

No extra medical exam is required beyond your normal DOT card.

Doubles Triples Endorsement Pay Bump Reality

Pay increases vary by region and carrier. In LTL operations, drivers with the endorsement often see an extra $0.03 to $0.08 per mile or a small weekly premium. Annual totals commonly land between $1,500 and $4,000 more, depending on miles and overtime. The bump is steadier in dedicated LTL fleets than in irregular over-the-road work.

Demand stays solid because fewer drivers hold the endorsement than standard tanker or hazmat credentials. Check current openings on the iMOGL jobs board to compare offers in your area.

Pros and Cons for Working Drivers

• More LTL terminal jobs and dedicated routes open up
• Slightly higher hourly or mileage rates at union and non-union carriers
• Extra practice needed for safe coupling in tight yards
• Some runs involve more physical work dropping and hooking pups

Safety records matter. Carriers track jackknife and rollover incidents closely on doubles, so clean logs help you keep the better-paying assignments.

Is It Worth Your Time in 2025?

If you already run regional or local routes and want steadier LTL work, the endorsement usually pays for itself within a year. Long-haul solo drivers who rarely see terminals may not notice enough difference to justify the test. Look at your current pay stub and the local freight mix before signing up for training.

iMOGL Market Intelligence shows consistent demand for doubles-qualified drivers in the Midwest and Southeast LTL corridors this year. For the latest pay ranges across CDL endorsements, see the 2025 CDL-A pay guide.

Talk with dispatchers at your current company or nearby terminals. Many will tell you straight whether they can put you on doubles runs right after you pass the test.
