Final answer:
You can only pass a stopped school bus when it's legal, safe, and all children are clear from the road. Pay attention to the bus's signals, as it's often illegal to pass when red lights are flashing.
Step-by-step explanation:
To safely pass a stopped school bus, you must do so only when you have confirmed that it's legal and safe in your specific location, and all children have cleared the road. Special attention should be given to the bus's signals; in many places, it is illegal to pass a school bus when it displays flashing red lights, which indicate that children are boarding or disembarking. In that case, one must stop and cannot proceed until the lights are turned off and the bus begins moving again. Pedestrian safety around school buses is paramount, and laws are in place to protect children from the dangers of traffic as they get on and off the bus.
