Poor Bus

Today I saw a weird incidence.For KL residents should know the Hop-On Hop-Off bus rite. When I was on bus no. 62, I saw the Hop-On Hop-Off bus was trapped at the tunnel. This was happened at the tunnel below a roundabout at Pudu. The poor bus was unable to pass through the tunnel because it is higher than the tunnel. Then traffic polices came to control the traffic so the bus can reverse and take the roundabout to go to another side. It was so lucky that the driver did not drive fast or else the top of the bus will be gone. I wonder whether there was any passenger in the bus or not. If got, dunno what was his feeling.
