How far must you stop from a school bus with its stop sign extended?

The correct answer is that you must stop at least 25 feet from a school bus that has its stop sign extended. This regulation is in place to ensure the safety of children as they board and exit the bus. When the stop sign is extended, it is a clear indication that children may be crossing the street or are close to the bus, and stopping at this distance provides ample time and space for children to move safely without the risk of being struck by a vehicle.

Maintaining this distance is crucial, as children are often unpredictable and may not be fully aware of traffic. By enforcing the rule of stopping 25 feet away, drivers can better react to any sudden movements by children and can contribute to a safer environment around school buses.

The other distances provided (10 feet, 15 feet, and 50 feet) do not comply with state laws that specify the required stopping distance from school buses, thus highlighting why the 25-foot standard is essential for ensuring safety in school zones.
