Why do school buses have crossing arms?

Answer 1

School buses are equipped with crossing arms to enhance the safety of children as they board and disembark. The crossing arm extends out from the front of the bus, creating a visual barrier that signals to drivers to stop and not pass the bus while children are crossing the street. This helps prevent accidents and ensures that children have a clear and safe path to and from the bus. Overall, the crossing arm is a critical safety feature aimed at protecting young pedestrians.
