I can't see the logic in that. If a breath test shows you are OVER the limit, what would you possibly have to lose by demanding a blood sample? It will normally take time for a doctor to arrive and take the sample, time that all works in your favour. The average body can shift 1 unit of alcohol in 1 hour - so by the time the blood sample is taken, especially if your are JUST over the limit, the result could be very different. I understand that the blood sample would take premacy as it is considered a more accurate test?
The way I see it there are only2 possible outcomes to a positive breath test:
Breath test over limit - leave it at that - GUILTY.
Breath test over limit - take your chances - demand blood test.
Then either:
1. Blood test over limit - GUILTY.
2. Blood test under limit - NOT GUILTY.
Where;s the disadvantage?
NOT that I am condoning deliberate alcohol consumption before a period of duty, but as someone already said, we all make a mistake from timt to time.
