When approaching a school bus stop, what is the correct distance to activate flashing lights?

Answer: B — 100 feet

Activating your flashing lights when approaching a school bus stop is essential for the safety of children boarding or exiting a school bus. The correct distance to activate these lights is 100 feet. This distance allows sufficient time for other drivers to react and slow down, ensuring the safety of children who might unexpectedly cross the street. Setting the distance at 100 feet strikes a balance between allowing drivers enough time to see the lights and react appropriately, while also reflecting the typical stopping distance at moderate speeds. It provides a clear indication to all road users that they need to prepare to stop, creating a safer environment around school buses.
