Which statement about large trucks in roundabouts is true?

• A. Large trucks may cross into other lanes while turning in roundabouts
• B. Large trucks must stop at all roundabouts
• C. Large trucks never cross lanes
• D. Large trucks may not use roundabouts under any circumstances

Answer: (A)

In roundabouts, large trucks often require a wider turning path than smaller vehicles. To complete the turn safely and avoid hitting the curb, a truck may swing into the adjoining lane within the roundabout and then merge back onto the exit lane. That makes the statement true: large trucks may cross into other lanes while turning in roundabouts.

The other ideas aren’t correct because you don’t have to stop at every roundabout—vehicles yield to traffic in the circle and only stop if necessary. Large trucks aren’t prohibited from using roundabouts, and it’s not accurate to say they never cross lanes; their wide turns can require brief lane changes.
