Which statement about center island size is true?

• A. Roundabouts have a larger center island.
• B. Centers are the same size.
• C. Roundabouts have a smaller center island; traffic circles have a larger center island.
• D. Center island size is irrelevant to operation.

Answer: (B)

When you drive through either a roundabout or a traffic circle, the central island mainly shapes the path you take and helps slow cars, but it isn’t what changes how you operate the intersection. The key rules are to yield to traffic already in the circle, then proceed when it’s safe and travel around the island in the circulating lane. That’s why the statement that centers are the same size is the best answer: the size of the central island isn’t used to differentiate how you drive around a roundabout versus a traffic circle. The driving actions—yielding on entry and circulating—remain the same regardless of slight differences in island size. The other options imply a size-based difference that isn’t a standard rule, so they don’t fit as well.
