What should you do if you approach a school bus with its red lights flashing?

When you approach a school bus with its red lights flashing, the appropriate action is to stop your vehicle and wait until the lights stop flashing. This law is in place to ensure the safety of children getting on or off the bus. The red lights signify that children may be crossing the street or are in danger of being in the path of vehicles. By stopping, you provide a safe environment for these children, allowing them to board or leave the bus without the worry of oncoming traffic. It is a crucial part of road safety regulations to protect vulnerable pedestrians, especially in areas where children are frequently present.

Continuing to drive, honking the horn, or driving past slowly does not provide the necessary precautions to ensure children's safety and may put them at risk of injury. Thus, stopping your vehicle is the correct response in this situation.
