Can you drive?

This morning an A Re Yeng (V-S1016, F5) bus blocked traffic twice because it could not turn right at first and then later on left at a different road. Firstly is kept on driving after the light turned amber, could not make the turn and simply stood there, whilst the traffic light changed to green twice. The car on the other side of the bus - which apparently prevented the driver from turning had to manoeuvre his car around so that the driver could make the turn - and that after he stopped quite close to the curb as he want to turn left into the street the bus came from! Can you please have these people going for driver's licenses or at least get them GPS, because it seemed that the driver this morning had no clue what to do or where to go.
