School buses carry millions of children every day to institutes and safety of the bus occupants is a major concern for all. The 'Yellow Bus Story' follows the story of two such school going children and a few other characters, as they learn and share their experiences of travelling in a school bus, safe and sound.
Peeli Bus is the school bus that comes to pick up and drop the children of AITS. 'PB' is the name coined by Harry for the bus because he sees it as a fun place where he meets many friends.
Unknown to all the children, PB has a life of her own. She cares about the children travelling in her and wants to communicate that school bus safety is important for everyone.
