Misdemeanor DUI Penalties in Arizona
The Facts About a Misdemeanor DUI in Phoenix & Scottsdale, Arizona
Yes, Arizona’s DUI penalties are bad. However, for purposes of getting you to sleep tonight, you should know that most misdemeanor DUI cases DO NOT result in long terms of jail.
Even the thought of spending a minute in jail can be is terrifying. Accordingly, your lawyer should do everything possible to prevent you from spending even one minute in jail. But, in the event of a conviction, the required time in jail is likely not as long as you imagined.
Jail math does its best to tell you that 2 + 2 = 7. Let’s see if we can make things add up correctly.
Misdemeanor DUI Penalties
MANDATORY MINIMUMS
*CURRENTLY in Maricopa County home detention is only permitted in city courts. If your case is prosecuted in a justice court then home detention is not permitted. Thus, an Extreme DUI can only be reduced to 9 days jail and a Super-Extreme DUI to 14 days jail. And yes...this makes no sense.

Second DUI Penalties
MANDATORY MINIMUMS
*PREVIOUSLY in Maricopa County home detention is only permitted in city courts. If your case is prosecuted in a city court then home detention is available after 20% of your sentence. Therefore, a person sentenced to a 2nd Extreme DUI could serve 24 days in hail and then serve the remainder of the sentence on home detention. A second Super-Extreme DUI conviction would require an initial 36 days of jail before home detention. That changed in September 2020.

COVID-19 & DUI Home Detention
Here is the latest administrative order regarding home detention for Arizona DUI cases: 2020-83
Subsection I, of Arizona’s Extreme DUI statute (A.R.S 28-1382) provides a method to substantially reduce the amount of jail if convicted of Extreme or Super-Extreme DUI.
After a conviction, the Arizona Motor Vehicle will be notified by the court of conviction and then issue an interlock requirement. Notice of the requirement is sent through the mail. This process can take weeks (in some cases even longer). Under subsection I, if you get the interlock at the time of sentencing (instead of waiting until MVD issues it after sentencing) the court can reduce your sentence as follows:
Keep in Mind:
- Discretionary - the court has to order it.
- First Offenses - not eligible for 2nd offenses.
- Extents Interlock - no credit for early installation.

Hiring an Experienced DUI/DWI Attorney in Phoenix, AZ
Arizona DUI law is extremely complicated and has severe consequences. DUI law is commonly referred to as a minefield. An attorney must be competent in the Arizona Rules of “Criminal” Procedure, the Arizona Rules of Evidence, the United States and Arizona Constitutions, and the Arizona Department of Motor Vehicles Rules and Regulations.
An attorney cannot do anything for you unless he or she has extensive experience in these areas. Police officers are only human and do commit legal errors. However, only an experienced DUI attorney will be able to find these errors and use them to help his or her client.
You should choose an experienced DUI attorney for the same reason you should choose a qualified doctor. If you break your wrist, you go to a doctor that specializes in wrist injuries. When you are charged with a DUI, you should hire a qualified DUI attorney.
An experienced Arizona DUI attorney can analyze your case for legal errors and defenses. He or she can have blood samples independently analyzed, look for suppression issues, review calibration / COBRA records of breath machines, find the right expert witnesses for your trial, and assist you with your driver’s license issues.
