What statement is true about large trucks in roundabouts?

• A. All drivers should be cautious and avoid passing large trucks in roundabouts
• B. Large trucks may cross into other lanes while turning in roundabouts
• C. Large trucks need more space than normal-sized vehicles in roundabouts
• D. Large trucks always stay in their own lane when turning

Answer: (B)

When trucks turn in roundabouts, their turning geometry requires extra space. A truck has a long wheelbase and often a trailer, so the front wheels swing wider toward the center as it enters the roundabout, while the rear wheels follow a different path. This can cause the entire vehicle to cross into an adjacent lane or even span lane markings as it completes the turn. That’s why it’s true that large trucks may cross into other lanes while turning in roundabouts. They do need more space overall, and you shouldn’t assume they’ll stay neatly in one lane; give them room and don’t try to pass.
