A big combine harvester in front of you wishes to turn right. What is correct?

Your answer is correct because a large combine harvester uses a wide turning radius and usually swings out to the left before making a right turn to navigate the turn safely. This maneuver is necessary due to its size and limited maneuverability. Additionally, the harvester will slow down significantly before turning to ensure control and safety. The option that it "cannot swing out due to rear-wheel steering" is incorrect because many large agricultural vehicles do have rear-wheel steering, but this allows for a wider swing rather than preventing it. Understanding that large vehicles require extra space and slow down before turns helps you anticipate their movements and drive safely around them.
