Invalid Yellow Box Junctions
Here are two examples of yellow box junctions with four straight sides, and two curved sides. They clearly do not comply with the above diagrams.
These box junctions are on Colney Hatch Lane, London, N10
A little further down the road
Yellow Junction box outside Wood Green Bus Garage. Notice that there is no side road and therefore a junction does not exist. A yellow box junction must be at the junction of at least two roads, a yellow box at a bus garage exit and a road as in this case would not be valid.
