Hi All
Firstly, apologies if this is in the wrong forum (Admins please feel free to move accordingly).
Q: Where/when does a "no u-turn" sign become effective? As soon as it becomes visible, from the signpost onwards to which the sign is affixed or does it all boil down to the TMO that is in effect?

When people stop making U-Turns

Sorry, couldn't resist.
On a stretch of road a traffic order will specify the length of the restriction from and to specified kerb measurements, and the start and end signs should be located at these points.

What if the first 'no u-turn' sign that you see is in the middle of the stretch of road governed by the TMO? Is the TMO effective prior to the sign?
