Sounds like this just short circuits law suits against drunk drivers. Most likely the family of a bread winner killed by a drunk driver is going to sue for damages including loss of family income, etc. Most likely these families will win their lawsuits. However, collecting on such judgements does not always happen. Liability insurance covers some of the damages but what it the drive does not have liability insurance? I am assuming this law will allow the state to garnish wages and liquidate assets to ensure payments are made. In the end the family of the deceased avoid legal fees, and time consuming trials.
Is this a bad thing? I don't think so but I believe in most cases it is not going to amount to much.
