Practice question

What is the primary reason a heavy vehicle's turning circle (swept path) is larger than that of a car?

  1. Heavy vehicles have wider tyres
  2. Heavy vehicles must travel faster to turn
  3. The greater length between front and rear axles causes the rear wheels to follow a different (tighter) arc than the front, requiring a wider overall swept path
  4. Heavy vehicles use a different type of steering rack

Answer: C — The greater length between front and rear axles causes the rear wheels to follow a different (tighter) arc than the front, requiring a wider overall swept path
