Kansas City, Mo. ? A new device could mean the end of sleeping students being left on school buses.

The Kansas City Star reported Wednesday that a growing number of districts are adding alarms that sound if drivers fail to walk to the back of their buses to deactivate them after finishing their routes.

Transportation provider First Student has installed the devices on all its school buses. The company transports students for several area school districts, including the Lawrence school district, as well as Shawnee Mission, Blue Valley and Olathe.

Raytown school district’s transportation director, Dennis Robertson, says the alarms are another example of how school districts have tried to make their buses safer.
