An Idaho school bus driver has been arraigned on charges of drug possession and injuring children after she was spotted driving erratically on Monday. Police say 33-year old Theresa Mahurin failed sobriety testing and officers found what appears to be methamphetamine in her purse. Police say people called emergency officials to report the driver going too fast around curves, too slowly along others and using the bus lights improperly. The bus company was able to intercept the morning route and had a replacement bring the children to school. Police say none of the children was hurt. The driver faces charges of injuring children because state law allows the charge if an adult drives child passengers while intoxicated.
