what always gets me is this. in this cash strapped council/police force etc. who is paying to replace all the speed restriction signs down the bypass. the restriction cannot be enforced until all these sign are properly displayed.

BY THE WAY WE ALL KNOW THE SPEED LIMIT ON THE BY PASS DONT WE BOYS. only those who have been booked for speeding before now I suspect
