Hidden Speed Trap

Can they do this? legally?

Are the operators of speed traps allowed to use their own vehicles to partially obscure the high visability markings on the rear of the speed camera van?

That's what's happened at this one near Tain in northern Scotland. Was it deliberate? I don't know. But since the cameras must be clearly marked, obscuring those markings would seem to be against the spirit if not letter of that regulation.

And I don't yet know if it 'got' me.
