You are following a large truck that is signaling a right turn. You should anticipate
- the truck swinging right.
- the truck stopping suddenly.
- the truck turning close to the right curb.
- the truck swinging left. ✓
Answer: D. the truck swinging left.
You should anticipate the truck swinging left as it sets up for the right turn.
Why this is the answer
The handbook says a large vehicle making a right turn may first swing wide to the left, then come back around to the right so it doesn't hit the right curb. That is why you should expect the truck to move left before it turns. Do not fill the gap that opens in the right lane; stay back until the truck has cleared the turn.
Why the other answers are wrong
- A. the truck swinging right. — A right turn does not start with the truck swinging right; the handbook describes it swinging wide left first before coming back around to the right.
- B. the truck stopping suddenly. — The passages do not say a large truck making a right turn will stop suddenly; the warning is about the space it needs and the swing of the turn.
- C. the truck turning close to the right curb. — The truck may actually swing away from the right curb first to avoid hitting it, and after the front clears the corner the rear can move partly back into the right lane.
Remember it
If a big vehicle signals right, expect the cab to drift left first and keep your lane open behind it.
