Generally you have to do a lot to get banned for life - remember Germany is run by car lobbies, they are not interested in banning people from driving,
> you have to supply hair samples
That seems like an idea that could be useful, over here, but we have a pretty strong sin lobby, so it's unlikely to happen.
Sin is ok here, that's why our policitians have little or no hair ;)
For comparison, to get a similar penalty by speeding you would have to exceed the speed limit by 51 km/h (32 mph).
There are many additional related offences you could commit, with different consequences. Repeat offences to the above, for example, are punished more severely: you get 3 months instead of 1 and the fine is doubled and tripled for the second and third offence, respectively. Already with a blood alcohol level of 0.03% you risk legal consequences, e.g. if you make an error while driving. If you endanger someone else (or property) with that level you are committing a crime, will lose your license, and can go to prison. If you are in your probationary period (two years after acquiring your license), any nonzero level is an offence.
Losing your license is generally temporary. You are blocked from re-acquiring it for some time, depending on the offence (at least 6 months, but can be multiple years). You have to complete an MPU, which certifies your ability to safely drive. For alcohol based offences, this would include demonstrating that you have reduced your consumption significantly. This can be quite harsh; you may, for example, be required to show complete abstinence for a period of one year. Of course, you are also looking at costs close to $1000 for the MPU alone. It is possible to get permanently blocked from driving, but it's quite difficult, I believe.
In the UK you get a minimum 12 month ban, an unlimited fine (which are based on income and have been quite big in the past (Dec of Ant and Dec got an £86000 fine). I don't think this approach is uncommon in Europe.
With a valid employment reason (such as snow plow operator) you can get an employment only permit. Your insurance will easily be $1000 a month just for basic liability. I’ve known a few guys in this situation.
The bigger problem is people who are judgment proof and don’t mind spending some time in jail. They just drive drunk over and over and don’t care if their car (which is often a relative’s) gets impounded. They have no valid licence and no insurance. Short of permanent incarceration, there isn’t much they can be done about such people.
Yep, when you get down to this root fact, it's nearly impossibly to _actually_ stop someone from driving a car. If you make insurance mandatory, they will still not buy insurance. If you revoke their license, they will keep driving without it. If you fine them, they just won't pay. If they go to jail for it, they'll resume driving when they get out.
