Permissible Blood Alcohol Limits and Driving

"If you drink, dont drive. Dont even putt." - Dean Martin

Alcohol content in blood is measured either as a percentage by mass or by mass per volume or a combination. For example,

  • BAC of 0.20% can mean 2 grams of alcohol per 1000 grams of an individual's blood
  • Or it can mean 0.2 grams of alcohol per 100 millilitres of blood.

Permissible Blood Alcohol Limits while driving light motor vehicle (e.g. passenger car)

Even Dubai is quite strict for drunken driving. They take photos - from Police cameras and people get booked with hefty fines.

How does 30mg/100ml translate in terms of the amount of Alchohol that can be consumed by an individual and keep him within this safe limit. Will having a bottle of beer keep within this safe thresh hold. I know BAC depends on a lot of other factors...but I guess a safe limit can be arrived at in terms of bottles of beer.....or a CHOTA or a BADA peg.......Cheerio.
