I agree with the 0.00 blood alcohol for driving that way we eliminate the guess work of 'am I ok to drive? Have I had too much?' It's clear if you've had any alcohol you shouldn't be driving. However, as others have said, I don't think someone who had a glass of wine with a meal several hours before driving should be penalised the same as someone who is completely hammered. There should be a sliding scale of penalties so that blowing up to .05 would be similar to receiving a speading fine with demerit points. Anything over .05 should be a greater offence. And while we're on the subject, they really need to increase the penalties. The legal system is far too tolerant at the moment- these things are not just an honest mistake.
