Free AK CDL Double/Triple Trailers Practice Test 2025

Perfect for first-time and renewal CDL/CLP applicants, and those adding endorsements
Based on 2025 AK commercial driver's license manual
Triple-checked for accuracy
Updated for April 2025

Alaska’s huge size, difficult climate, and rugged terrain make truck transportation a critical industry. Double tractor-trailers (tractors pulling two trailers) are less common than in the Lower 48. Still, they are used in several key sectors to maximize freight efficiency and reduce fuel costs.

In logistics, double trailers help intermodal and less-than-truckload (LTL) carriers improve their efficiency. UPS and FedEx use double-pup trailers in Alaska as elsewhere. In the state’s key energy sector, some companies employ double tankers to haul crude oil, fuel, or chemicals. Finally, the state depends on food shipments from the Lower 48. Companies like Costco and Carrs-Safeway receive shipments in double-trailer grocery trucks.

Triple trailers are not legally allowed in Alaska.

If you want to pull doubles or triples, you must obtain a Double/Triple (T) endorsement on your Class A CDL. For this endorsement (assuming you are already qualified to drive combination vehicles), you must pass the Double/Triple knowledge test (but no additional skills test). This test covers such topics as safe handling, air brakes, coupling and uncoupling, pre-trip inspections, rollovers, and trailer sway.

This knowledge test is based on the official Alaska CDL manual (Alaska CDL Handbook 2025), especially Chapter 7: Doubles and Triples. You likely studied other parts of this manual to pass your General Knowledge test and Combination knowledge test.

We offer a set of tools to complement the official manual with intensive training. This is one of our tools: the first of five Alaska Doubles and Triples Endorsement Practice Tests. This practice test is based on the official CDL manual, like the Double/Triple knowledge test. It’s up to date as of April, 2025. The 20 multiple-choice practice questions and answers on this practice test address such topics as air lines, converter dollies, coupling, following distance, rearward amplification, and rollovers.

Our AI Assistant can help you answer any practice questions. It can give you a hint or an example or answer any of your own questions about driving. If you still miss the question, the AI Assistant will immediately give you the correct answer and an explanation.

This practice test has no time limit; take all the time you need to learn the material covered by this practice test. Not satisfied with your final score? You can retake this practice test as often as you wish. Each time, the order of the questions will be randomized.
