Sample CDL Doubles & Triples practice questions
Try a few representative questions below. Each includes the correct answer and a short explanation — the same style you'll see in the full practice test.
- Question 1Air Brake Systems
When driving a doubles or triples combination vehicle, what is the primary safety concern related to the trailer's air brake system that differs significantly from a single trailer setup?
- A.The necessity of ensuring all trailer air tanks are independently drained to prevent freeze-ups.
- B.The increased risk of trailer brake-away due to the longer air lines and potential for leaks.
- C.The potential for uneven braking force distribution between trailers, leading to jackknifing.(Correct)
- D.The need for a higher air pressure setting to compensate for the increased braking force required.
Explanation
With multiple trailers, the air lines are longer, and there's a greater chance for variations in brake application pressure between trailers. This can cause one trailer to brake harder or softer than others, increasing the risk of instability and jackknifing, especially during emergency braking.
- Question 2Pre-Trip Inspection
You are inspecting the gladhand connections on a triples combination. You notice a slight hissing sound from the service line gladhand of the second trailer. What is the most immediate and critical action you should take?
- A.Tighten the gladhand connection, as a small leak is usually not significant.
- B.Record the leak in your logbook and proceed, noting it for future repairs.
- C.Immediately attempt to repair the leak with temporary sealant before proceeding.
- D.Disconnect the second trailer and proceed with only the first trailer, if legally permitted.(Correct)
Explanation
A hissing sound from a service line gladhand indicates a leak. In a doubles or triples setup, this leak can impair the braking performance of the affected trailer and potentially the entire train. Disconnecting the affected trailer is the safest course of action to ensure the remaining combination can be safely operated.
- Question 3Turning and Maneuvering
What is the critical difference in trailer tracking between a doubles combination and a triples combination when making a right turn?
- A.In doubles, the first trailer tracks inside the tractor's path, while in triples, the second and third trailers track progressively wider.
- B.In doubles, the first trailer tracks wider than the tractor, while in triples, the second trailer tracks wider than the first.
- C.In doubles, the first trailer tracks wider than the tractor, while in triples, all trailers track inside the tractor's path.
- D.In doubles, the first trailer tracks inside the tractor's path, while in triples, the second trailer tracks inside the first, and the third tracks inside the second.(Correct)
Explanation
When turning, the rear of each trailer follows a tighter arc than the front. In doubles, the first trailer cuts inside the tractor's path. In triples, the second trailer cuts inside the first trailer's path, and the third trailer cuts inside the second trailer's path, requiring careful observation of all trailer positions.
