What must a driver do when approaching a stopped school bus with flashing overhead lights?

When a driver approaches a stopped school bus that has its overhead lights flashing, the law requires the driver to stop before the bus and refrain from proceeding. This regulation is in place to ensure the safety of children getting on or off the bus, as they may be crossing the road or otherwise unrestricted in their movements.

The flashing lights serve as a clear indication that the bus is loading or unloading passengers, and failing to stop poses a significant risk of endangering children who may be in the vicinity. It is a legal requirement in many jurisdictions, including Ontario, to halt your vehicle whenever you see a school bus with its lights activated, regardless of the direction from which you are approaching the bus.

In contrast, maintaining speed would not only violate the law but also increase the potential danger to children. Stopping only if children are crossing overlooks the fact that children may be getting on or off the bus and may not be visible to the driver. Honking to alert the bus driver is not only unnecessary but could potentially distract the driver or startle children. Therefore, stopping is the only appropriate and safe action in this situation.
