A large truck is ahead of you and is turning right onto a street with two lanes in each direction. The truck:
- May complete its turn in either of the two lanes.
- May have to swing wide to complete the right turn. ✓
- Must stay in the right lane at all times while turning.
Answer: B. May have to swing wide to complete the right turn.
A large truck ahead of you may have to swing wide to complete a right turn.
Why this is the answer
The manual explains that large trucks often shift left before making a right turn because the turn is wide. That leftward movement is part of how the truck sets up for the turn, so a driver behind it should expect the truck to need extra room rather than assume it will turn tightly in the right lane. The passage also warns that you may not be visible to the truck driver in the wide area the truck needs for turning.
Why the other answers are wrong
- A. May complete its turn in either of the two lanes. — Nothing in the passages says a large truck may choose either lane to finish the turn; the turn material says a right turn normally ends in the right lane unless signs direct otherwise.
- C. Must stay in the right lane at all times while turning. — A truck does not simply stay in the right lane throughout the turn; the manual says it may move left first because its right turn is wide.
Remember it
If a truck shifts left before a right turn, do not squeeze past; that space is part of its turn.
