When passing a large vehicle, the driver of a small vehicle must be prepared for:
- Loud noises.
- Excess air pollution.
- Wind gusts produced by the large vehicle. ✓
- Falling vehicle parts.
Answer: C. Wind gusts produced by the large vehicle.
When you pass a large vehicle, be ready for wind gusts produced by that large vehicle.
Why this is the answer
The handbook warns that a strong gust of wind can push a rider across a whole lane if they are not ready for it, and it adds that wind gusts coming from large trucks in the other lane are a hazard too. The point is that big vehicles push air around them, so a driver in a smaller vehicle should expect that push when passing and be ready to correct. The handbook does not describe any other effect of passing a large vehicle.
Why the other answers are wrong
- A. Loud noises. — Noise is not something the handbook lists as a hazard to prepare for when passing a large vehicle.
- B. Excess air pollution. — Extra air pollution is not mentioned in the handbook as a concern while passing.
- D. Falling vehicle parts. — The handbook says nothing about parts falling from a large vehicle as something to prepare for.
Remember it
Think of a big truck as pushing a wall of air beside it, so keep a steady grip as you go by.
