i don't know if anyone else is aware of this, since i was told, by a bulgarian friend, that he saw it on the telly, yesterday. not only should we all be sporting our new vignettes, old vignettes MUST be removed from the windscreen. failure to do so may result in a 100 leva fine. i don't know if that's 100 leva per vignette, but if it is, i could cop for a 500 leva fine.
they've been left on there, because it's a nightmare to remove them. easier to get a new windscreen fitted, i thought, until i heard on here that a hairdryer is the way to do it. good job i keep one handy in the car.
PS. i think, maybe, that this requirement has always been there, but possibly they've just noticed an untapped revenue source, and will be enforcing it.
