Before stepping out for a night of fun, you need to know about these laws on drunken driving. Drunken driving can be described as driving under the influence of alcohol. To such an extent that you can't control the vehicle. he permissible limit of blood alcohol in India is 0.03%. Which means that 330ml of beer or 30ml of whiskey or rum is under the permissible limit. Rather than having to appear at court to pay fine, it is better that you ask someone sober to drive you or take a cab.
