No doubt the medical experts will be queuing up to jump in and tell me I’m wrong, so read carefully what is written.

My understanding is that for the average person it can take up to 48 hours for alcohol to leave the system. So that innocent bedtime drink could have serous repercussions next morning.

Although zero tolerance could be desirable isn’t going to be practical to achieve this. There are too many innocent ways to fall foul of the breathalyser. Sherry trifle. Xmas pudding. What about a pub landlord who spends hours amongst alcoholic fumes direct from the product being sold and also from the breath of the clientele. Would breathalysing him come back zero or would there be a smidgin of alcohol in his breath.
