Final answer:
The speed at which you may pass a stopped school bus directly in front of a school is 10 mph but always verify local traffic laws.
Step-by-step explanation:
When a school bus has stopped directly in front of a school to pick up or let off children, you may pass from either direction at a speed of not more than 10 mph. This is the standard speed limit set for safety reasons; however, it's essential to always check the local traffic laws as they may vary by state or municipality. When encountering a stopped school bus, it is crucial to proceed with caution and be vigilant for children entering or exiting the bus.
