In the context of commercial driving, what is a turnout?
- A place for a train to pull off the main railway track to let other trains pass
- A place where the road widens
- A runaway lane
- A place to pull off the road to let other vehicles pass ✓
Answer: D. A place to pull off the road to let other vehicles pass
In commercial driving, a turnout is a spot where you leave the roadway so other vehicles can get past.
Why this is the answer
The handbook's industrial-road section defines a turnout as an area you pull into off the road to let other vehicles go by. It also says that on a narrow road you should use one to yield to a loaded truck, and that you should yield to a loaded truck descending a steep hill on an industrial road. That matches the choice about pulling off to let other vehicles pass. The passage does not describe a railway siding, a widened road, or a runaway lane.
Why the other answers are wrong
- A. A place for a train to pull off the main railway track to let other trains pass — A railway siding for trains is not what the passage describes; the handbook's turnout is a roadside place for vehicles, not a train track.
- B. A place where the road widens — The passage does not say a turnout is where the road widens; it says you pull off the road to let others pass.
- C. A runaway lane — A runaway lane is not mentioned in the passage's definition; the turnout is for yielding to other vehicles, not for runaway vehicles.
Remember it
Picture a narrow industrial road: you tuck off to the side so a loaded truck can get by.
