The Wisconsin Assembly has approved a plan requiring a mandatory 18-month prison sentence for anyone convicted of operating while intoxicated, fifth offense.  Lawmakers want to make it tougher on repeat drunk drivers.  They also voted for a plan to give prosecutors more time to see if a driver has an O-W-I in another state before making a decision on charges.  The sponsor of the bill, State Representative Jim Ott, says this isn’t about locking more people up – he just wants drivers to think about their drinking and driving choices.
