.08 sounds a rather liberal limit to me. But then again, I live in what our Swedish neighbours once called the "last Soviet state" ... Here, the rules are as follows:
The legal limit is .02, which in practice means that one bottle of light beer is all you can allow yourself to drink before driving.
Up to .05, the punishment is a fine, up to 1 months pay - so the more you earn, the bigger the fine. You may also lose your license for a limited time, but it's not certain.
From .05 to .10, the fine is 50% bigger, you will inevitably lose your license for at least 12 months, and you'll be given a suspended jail sentence - typically three weeks.
Above .10, the fine is the same, the license goes, but depending on the circumstances the jail sentence may be unconditional and you go to jail.
Above .15 you go to jail anyway, maybe also longer than three weeks, and you lose your license for at least two years.
It has to be said, none of these punishments are based on breathalyzers only. If the breathalyzer indicates you have been drinking, you are taken to the police station for a blood sample, and the alcohol content in the blood sample is what determines your punishment.
Now, what do I think of this? First and foremost, I think that for really drunk driving, one might just as well withdraw the driving license for life (at least for a second offense). If you get pissed and then drive, you're an idiot and should not be allowed to drive any motor vehicle.
When it comes to the punishment for lesser violations, though, I find them incredibly strict - especially when compared to the punishment for other violations of traffic laws. For example, it is not allowed to use a handheld phone while driving. I'd say the level of distraction is comparable to driving with a low alcohol level, but the fine is less than 1.000 NOK (compared to a potential 15.000 for driving with an alcohol level of .03). Also think about the following: Driving after a night of no or very little sleep has been shown to impair your concentration as much as a blood alcohol level of between .05 and .08. Yet, if you are caught driving erratically and the police observes that you're just very tired, all that happens is that you're told to take a rest before driving on. So, the punishments are not near to proportional.
