A "No buses (over 8 passenger seats)" sign restricts which type of vehicle?

The correct answer emphasizes that the sign specifically restricts buses that have more than 8 passenger seats. This means that any bus designed to carry a larger number of passengers, potentially including larger vans or minibuses that exceed this seat capacity, are not allowed to use the roadway or area marked by the sign. The language of the sign is clear and precise, aiming to limit access to those vehicles that fall into this specific category.

The focus on buses with over 8 passenger seats indicates an intention to manage traffic effectively, possibly due to road capacity, safety concerns, or preventing congestion. Understanding the wording of the sign is crucial for recognizing what is explicitly prohibited, which is why this answer is the most accurate for the given question.
