The relevant paragraph would be “§ 81 StGB: fahrlässige Tötung unter besonders gefährlichen Umständen”
(Art. 81 of the Austrian Criminal Code: negligent homicide under especially dangerous circumstances). The maximum penalty is three years of prison.
Additionally, if it can be expected, due to the perpetrator’s addiction to a drug (including alcohol), that he will commit further crimes caused by that addiction, the perpetrator is to be remanded to a rehab center (for as long as necessary, but no longer than 2 years).
But that does not mean the maximum penalty is four times three years plus mandatory rehab.
Sentences are always served concurrently, consecutive sentences do not exist. Any mandatory rehab time would also run concurrently.
A teenager’s binge drinking and his lack of judgement in drinking and driving does not usually constitute an addiction, though.
The perpetrator was 16 years of age at the time, so the maximum penalty is halved to 18 months. For a first offence, sentences of less than 2 years are usually suspended in their entirety, with a probationary period of at most three years. If I read that paragraph correctly, it says that for sentences less than 2 years, two thirds of the sentence have to be suspended, which leaves 6 months of prison + 12 months of a suspended prison sentence with a probation period of 3 years would be the absolute theoretical maximum.
In any case, all conditions of probation would be lifted after at most three years. And after five years, the sentence will be struck from all publicly accessible databases, so no worries about future employment, either.
