Doubles & Triples Practice Question 23

TDoubles & Triples · Question 23

When the rear trailer of a double sways in a crosswind, you should:

• ASpeed up
• BReduce speed and steer smoothly to dampen the oscillation; consider pulling off if it persists
• CBrake hard
• DUse the trailer hand valve hard

Correct answer: B. Reduce speed and steer smoothly to dampen the oscillation; consider pulling off if it persists

Why: Speed amplifies the sway. Reduce speed gently and avoid abrupt steering or braking. Pull off in a safe location if the sway becomes uncontrollable.

How this question fits the Doubles/Triples test

Each additional articulation point multiplies rearward amplification. A driver pulling triples must steer earlier, brake sooner, and inspect twice as much equipment as a single-trailer driver.
