To be fair, I’ve yet to meet anyone in Glasgow who knows exactly what the Low Emission Zone means.
It doesn’t help that their online checker is extremely vague (‘your car may not qualify’ is the best it will say. Somehow I suspect the computer that issues the fines won’t act all coy when spitting out its tickets).
As it happens, I’m sure my 10 year old diesel Berlingo doesn’t qualify, while my 5 year old petrol Panda does. Neither are electric, obvs. Your nuisance caller was talking out of his bahookie on all points.
