What is the correct action when you see a school bus with its red lights flashing?

When you see a school bus with its red lights flashing, the correct action is to stop your vehicle in both directions until the lights stop flashing. This rule is in place to protect children who may be getting on or off the bus. The flashing red lights serve as a warning that the bus is either picking up or dropping off passengers, and stopping ensures the safety of those children as they cross the road or approach the school bus.

Failure to adhere to this rule can result in severe penalties, including fines and points on your driving record, as it puts children at risk. It's essential to recognize that this rule applies regardless of whether you're approaching the bus or traveling in the opposite direction—safety takes precedence in these scenarios.

The other choices do not align with safety protocols established for school bus situations. Slowing down and proceeding with caution does not provide the necessary protection for children, as it allows for the possibility of accidents. Passing the bus if no children are present overlooks the critical safety measures in place for all scenarios, and honking to alert the bus driver is unnecessary and could distract or startle children. Thus, stopping when the red lights are flashing is the only correct and safe action.
