The correct answer is based on established safety regulations surrounding school buses. In speed zones exceeding 35 mph, it is mandated that flashing yellow lights be activated at least 300 feet before a school bus comes to a stop. This measure is intended to provide adequate warning to motorists that the bus is preparing to stop, allowing them sufficient time to slow down and ensure the safety of children boarding or disembarking from the bus.

Signaling well in advance is crucial in high-speed areas to minimize the risk of accidents, as drivers may not expect a stop in areas where they are allowed to travel at higher speeds. This regulation emphasizes the importance of caution in school zones, enhancing the protection of students during critical times.
