This question is best asked to an attorney in your area for guidance because how the court's view and react to these matters are really specific to the area i which you live.  In other words, how the court's rule can best be known to an attorney that practices in the area on a regular basis.  Generally speaking if the ordering of the interlock device is based upon the law - in other words it is a sentence that is required by the judge to give to cases with the same set of facts that come before the court - then there will be no leeway in the sentencing. I know that Florida has very strict laws on DUI and very strict sentences.  Ask for help.  Good luck.
