Maybe you have heard about this horrible accident in the spanisch province catalonia. While there has been some speculation about whether the driver has fallen asleep, I would like to draw attention to another point: The driver seemingly has only been injured slightly. I guess that the students which were killed didn't wear the seat belt. While this is obligatory, I know that this is treated very sloppily in catalunia. Did the driver remind the students to close the belt before beginning the voyage? I think this would have saved many lives in this case. Maybe you consider it too, the next time you ride a bus.
