Doubles & Triples Practice Question 4
TDoubles & Triples · Question 4
Rearward amplification:
- ADecreases with each trailer added
- BIncreases with each trailer added — sudden steering creates much larger swings at the rear trailer
- CHas no relationship to trailer count
- DOnly affects single trailers
Correct answer: B. Increases with each trailer added — sudden steering creates much larger swings at the rear trailer
Why: Each articulation point amplifies steering input. A 5-degree wheel turn at the tractor can cause much larger swings at the rear of a triple.
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.
