I believe that they have had some quite Draconian alcohol laws in Scandinavia for some time now, and that the 0mg rules there apply not only to cars,but to boats and horse-drawn vehicles !!There has been talk recently of having an alcohol ban for pleasure-boaters on the Thames and other British waterways, but who the hell is going to enforce such a rule ??
       I am,however,in favour of some sort of re-think on our existing drink-drive rules & regs ; The main problem with our existing limit is that is easy not to drink at all, whereas ,after one drink,one is more likely to have a second,and after a second drink,one is quite likely to have another,and after that,one is VERY likely to have another !! That is the nature of alcohol,and its effects on people----not ALL people,perhaps,but certainly enough for it to be a problem. So if a 0mg limit saved just ONE life,it would be worth it IMHO.
    Incidentally, I have only failed a breathalyser once, and that was all legal & above board, in the course of studying for my Certificate of Professional Competence in National Road-Haulage Operations !!
Now then ....what's the time ?? Sun's over the yardarm, so--Nunc Est Bibendum !!
