A new Arizona DUI law took effect on July 19, 2007 and is now one of harshest DUI laws in the country for DUI first offenders. 

The new Arizona DUI law targets first time ’super extreme’ offenders as they are now named if they submit a chemical test with a BAC of .20% or greater which works out to be more than twice the legal limit.  The new Arizona DUI law will require these super extreme DUI offenders to have a mandatory ignition interlock device installed in their vehicle.  In addition there is a mandatory 45 day jail sentence which the judge cannot suspend. 

 ** Ouch… **

One thing is for sure… with stiff penalties like that for a first offense you can be sure that many more cases will be contested and taken to trial than previously.
