Basically, all this survey indicates to me is that most folk are aware that it's probably unwise to have just one drink and then drive.
Unfortunately, 75% of these will indeed have the one beer or glass of wine which will place them above the the new limit - given the large measures being served in many pubs/restaurants

(BMJ was reported in the press as claiming this was also adding to the overall health problems caused by too much

aparently has some facts and figures from Switzerland. Like most Swiss laws - this one arrived via Kantonal referenda. It seems it was "successful" with an initial blitz campaign to enforce

and then they found that all their accidents in which excess booze in the system began to increase ,, with most of them being above the current UK one too.

These were the same who voted for the lowered limit as well in a referendum initially
Which more or less brings us back to the fact that enforcement of the current limit - never mind a lowered one, requires police to be out there to actually enforce this - with random tests if need be. Now we do test all involved in an incident to establish whether or not drink was a factor. That's a normal routine. If we have any reason to suspect any driver see driving erratically and/or we stop for any other reason is under any influence - then we are required to check them out. But that's here in an area which has a higher presence lurking around.

One of the main complaints we read in the press is that the police car is the "rare checkered breed"

- "the "red squirrel to the grey one"

with the s/cam being the fast multiplying "grey squirrel" and has the same effect - allegedly - on the local " plods"

So even if this comes to be - it still has to be enforced and one complaint throughout all the press bib bash articles seems to be that "we are not out there copping silly

s"
My own view? I will just advise all to drink orange juice or other soft drink if intending to drive a car shortly afterwards.
