This question isn't because I'm getting done for speeding or anything, but something about the signing on the main road into a shopping area (Broadfields retail park, Aylesbury for those who know the ares) has often puzzled me.
A map is in order..
The red things are supposed to be road signs, with the arrow representing the direction you would have to be facing in order to see the sign. For clarity I haven't shown the 40 signs as you enter the big roundabout at the bottom.
So as you enter from the bottom of the map, the limit drops to 30, then once you are past the one way street to McDonalds and the service road, it drops to 20. And yes, two of the 20 signs have been facing sideways for the last 6 months.
So my question is, looking at the two routes marked A and B on the map, what is the speed limit when they are on the roundabout at the top of the map
