The amount of Alcohol whould have been a problem for anyone if they had immediately began driving etc. This was 4 or more hours after I had consumed any Alcohol. Even the Officers admited thet it was very unusual to have any detectable Alcohol in the system after this time period. This is why i posed the question. The strength is not important, 1 beer or one shot of Whiskey should take a max. of one hour for you body to process.
Thank you for you comment.
You don't have to feel 'buzzed' or even your judgment impaired to be over the limit, technically. 3 1/2 beers are probably about 3 'units' of alcohol, (depending of course on the strength of the beer, as some are stronger than others) -which does sound just a bit over the driving limit to me....
That would go over on the breath test.
