I got this information from my friend in my yahoo mail , so I would share with you to see your opinion on this.
Don't Lower the Drink Drive Limit
Everyone understands that alcohol in any quantity impairs your judgement and reaction times and therefore agrees with the principle that if you drink then don't drive.
Yet distractions abound that also impair, for example,
Car radio
Phone ringing (even if you don't answer it)
Munching a sandwich
Drinking a coffee in one of those sealed paper cups
Spouse's chatter
Kids squabbling in the back seat
Billboards (especially with pretty girls or small print)
Worry (about work, mortgage, illness, whatever)
Traffic signs and road markings
There is therefore a certain level of alcohol impairment that is no more malign than these other acceptable diversions.
We do not know what this level is, but most jurisdictions have settled on a maximum blood alcohol levelthat is legal for driving, for example -
USA, Canada, UK, Ireland: 80 mg of alcohol per 100 ml of blood
Much of Continental Europe, Australia: 50mg/100ml (50mg for short)
In Ireland there have been commendable efforts over the past decade to enforce the law by (semi-)random breath-testing,upping the annual arrest rate for drunken driving from from 11,000 to 18,000 and applying penalty points licences. See this chart covering the period 1999-2008
According to a study by Lane Clark & Peacock, a respected international actuarial consultancy, this has helped reduce by about a third the road death rate per population and per vehicle, as this chart running from 1980-2007 illustrates (both are from an LCP study into road deaths in Ireland).
