Indeed. The reduction of the alcohol content of your blood is an exponential decay - i.e. it 'tends' to zero, but never actually gets there. If you have one drink there will be *some* alcohol content a week later, although it will clearly have no significant impact on your driving. Using a specific threshold is the only logical approach.

The UK drink-drive limit is roughly equivalent to 94ppm. 4.5% is 45,000ppm. So 4.5% ABV blood would be just shy of 480 times the legal drink-drive limit.

Actually, ignore that... It's 0.08% BAC (I was misreading the Wiki page - http://en.wikipedia.org/ wiki/Blood_alcohol_content - and, yes, I fully expect the bad jokes about "must still be pissed"...) so "only" 56 times. |
