Does anyone know what a bus driver is instructed to do when he
approaches a stop and there are two or more buses stopped there already.

There is then little chance of an intending psssenger making a clear
signal or of the driver being able to see any signal made.

So, I show hope that
(a) he will stop even if no signal is seen.
(b) he will let passengers off and on when at the back of the queue, if
it is safe to do so.
(c) he will stop again shen he later reaches the stop sign, lest any
passengers have not been able to get to an earler stopping position.

I hope he will NOT decide there are no passengers for his bus and
overtake the stopped buses.
