Given that buses have self levelling air suspension that is continuously adjusting the height based on the load, angle of the road etc, I assume the height listed for the bus is the absolute maximum it can go to rather than what it normally rides at?
I've been on buses a few times where the driver has raised the bus up quite a few inches (presumably just the front using the kneeling function) to go through water, so would that be considered the maximum height?
