Saw the scamera van on the A90 for the first time tonight.
It was on the south bound side, but after the roadworks! I was coming north at about 6.30, and the van was opposite from where the 30 limit starts on the north bound side, so I guess that is where the temporary crash barrier on the southbound side ends, just as the road bends to the left, and shortly before the end of the 30 limit.
Very sneaky - no sign of workmen, van not in the actual roadworks section, and placed just after a bend.
Of course it's all about safety, and not revenue generation.
