[Talk-GB] Where do speed signs take effect (from Changing "stub" cycleways to pavements)

[Chris Hodges]

More of an issue on big roundabouts is when it's possible to follow a 
lane in ideal circumstances at 40-50, and the implied limit is 60, but 
the lines of sight mean that a lower speed is needed. For example a 
tractor or cyclist pulls out when there's nothing visibly coming, but 
hasn't got very far when there's a car doing 40 towards their right hand 
side.  A speed limit then is both guidance an objective/enforceable 
measure of what's too fast.


So reduced speed limits on big roundabouts are becoming more common 
(Bristol and Kidderminster ring roads spring to mind) though by no means 
universal - not on the A47 in Norfolk and the one at Hardwicke 
(Gloucester) is emphatically 60 (Street View:

).  I cycle through this one sometimes (there's a bypassing bike path in 
one direction but it leads to a standing start onto the dual carriageway 
just after the roundabout)
