In which situations might you not need to stop for a school bus?

When determining when it's appropriate to not stop for a school bus, one critical factor is how the road is configured. If a school bus is on the opposite side of a divided highway or road with a physical barrier, such as a median, you are not required to stop. This is because the physical barrier separates the lanes of traffic, reducing the risk to children who may be crossing the road.

In addition to this, stopping for a school bus is primarily about ensuring the safety of children getting on and off the bus. When a bus is effectively isolated by a physical barrier, the need for a vehicle to stop is minimized, as there is no direct path for children to cross through moving traffic in that situation.

In other scenarios, such as having no children visible or a bus flashing yellow lights, a more cautious approach is warranted. The presence of yellow lights indicates that the bus is preparing to stop, and thus, caution is necessary, while the absence of visible children does not eliminate the responsibility to stop if required.
