Just got back from Bg and travelled from Sofia- Sliven/Yambol area and back again and spotted something unusual.
Whilst travelling from Sofia passing Chirpan at the very end of the motorway/dual carriageway there is a roundabout, we turn left towards Stara Zagara, about after mile I noticed a box on the other side of the road, which looked like a speed camera, another two were spotted between Stara Zagora and Nova zagora. My friend also said he has seen one near Sozopol/Primorsko way. I have also been told in the past that there is one near sunny beach.
There was no white markings on the road at the boxes, but did see an unusual sign miles away from the box, as per usual there was no speed signs anywhere near the boxes, so difficult to tell what the actual speed should have been
I don't remember seeing them in May when i did the same route.
Can anyone shed any light or have any information about the boxes.
