Free AR CDL Double/Triple Trailers Practice Test 2025

Want to drive combination vehicles with two or even three trailers or semi-trailers? You must obtain a Class A CDL (including passing the Combination knowledge test) and a Double/Triple (T) endorsement on your Class A CDL.

Is the T endorsement worth getting? Consider that the limited number of drivers with this endorsement and their specialized skills and additional responsibilities place them in high demand.

In Arkansas, the logistics sector (e.g., J.B. Hunt Transport Services, ABF Freight, FedEx Freight, and UPS Freight) relies heavily on double trailers for freight transportation. So does the retail and E-commerce sector (e.g., Amazon Fulfillment Centers and Walmart Supply Chain).

As of early 2025, drivers qualified to pull doubles or triples were earning $10,000 to $25,000 more per year nationwide than drivers of single-trailer vehicles, depending on the trailer configuration (Double Pup, Rocky Mountain Double, etc.).

To obtain the Double/Triple endorsement, you must pass the Double/Triple knowledge test. This test covers such topics as safe handling, air brakes on doubles and triples, coupling and uncoupling, pre-trip inspections, rollovers, and trailer sway. (Note that no special skills test is required for this endorsement.)

This knowledge test is based on the official Arkansas CDL manual (Arkansas CDL Handbook 2025), especially Chapter 7: Doubles and Triples. You likely studied other chapters of this manual to get your CDL. But you may have noticed this manual isn’t that easy to learn from. We can offer you more help.

This Arkansas Doubles and Triples Endorsement Practice Test, the first of five we offer, is based on the official CDL manual, just like the official Double/Triple knowledge test. It’s up to date as of October 2025. The 20 multiple-choice practice questions and answers on this practice test deal with air lines, converter dollies, coupling, following distance, rearward amplification, rollovers, and other topics.

Our AI Assistant can help you figure out the answer to any practice question. You can ask it to give you a hint or rephrase the question. You can also ask your own questions. If you still miss the question, the AI Assistant will immediately give you the correct answer and an accompanying explanation.

This practice test isn’t timed; take all the time you need to learn and master the material covered by this practice test. Disappointed by your final score? You can retake this practice test as often as you wish.
