The Yellow Box looks like it is at the bus stop. There is a stop
line there too. That means there is a traffic light.
We have a traffic light and bus stop in close
proxmity.
The student driver sees the Stop light, but sees no vehicle
infront so moves up to the Stop line and into the Yellow Box.
With experience, the driver will be able to see the traffic
lights, the Stop Line, the Yellow Box, any bus in the bus bay,
and any tailgating cars behind, all at once.
