It’s that time of year. Schools are opening, and children are traveling on school buses again. Over and over, students will hear the same admonitions: stay seated and talk quietly during your bus ride, don’t stand or play in the aisle, follow the bus driver’s instructions, and don’t throw things in the bus or out the window. These are all important rules of safety and civility that parents should discuss with their children. This year, however, you should consider spending extra time talking about those safety rules that are most likely to save your child’s life.
