What does "1ST" mean when it follows a DUI charge in AZ and are all the BAC levels charged in case BAC is challenged?

Asked almost 2 years ago - Flagstaff, AZ

I suspect "1st" means first offense, and that the prosecutor charges all of the BAC levels so that if the defense successfully challenges a particular level, all of the lower levels remain (sort of like a lesser included offense). Is this correct?

Additional information

Example charges:
DUI, 1st
DUI, BAC .08 or more 1st
DUI extreme, BAC .15 to .19 1st
DUI extreme, BAC .20 or more 1st.

    Lawyers agree


    Answered . The penalities for DUI's can be made more harsh if the person convicted has prior DUI convictions within a certain amount of time. And you are correct in regards to why all are charged. Plus, for the DUI/Impaired, if the prosecutor can prove the defendant's BAC was above .08%, then the jury can assume the driver/defendant was impaired.
