Do we have any regulation that the length of the bus should be this much metres or something. Is there any specification provided by the transport ministry?

Or is it that costly to have/maintain a toilet within the bus? Or the greedy bus owners dont want to lose that much amount of space, and have more seats instead? Why dont buses in India have toilets?

Last night I was coming back from chennai to bangalore. There was a lady along with her 4 or 5 year old son travelling. The kid felt like using the bathroom frequently. And every time, the lady used to goto the front and request the driver to stop the bus. Some drivers are rude and dont stop. But this guy was decent enough and stopped frequently. Thanks to the kid, we all got frequent toilet breaks. At the same time, its easy for guys. But very tough for women. I wonder why the bus owners/manufacturers dont think of buses with toilets?

Many people, especially families hesitate to travel in buses mainly because of this reason!
