Arizona DUI Penalties and Sentencing – Complete Guide

Arizona Has Some of the Harshest DUI Penalties in the Country

Arizona does not treat DUI as a minor offense. The state’s DUI sentencing structure is among the most severe in the nation, with mandatory minimum jail sentences even for first-time offenders, escalating fines that reach into the tens of thousands, and license consequences that can disrupt your life for years.

Understanding exactly what you face is the first step toward building an effective defense. The penalties vary dramatically depending on your BAC level, whether you have prior offenses, and whether aggravating factors are present. A first-offense standard DUI carries mandatory jail time. An aggravated DUI is a felony with a presumptive prison sentence of 3.5 years.

Brad Rideout is a former Arizona District Attorney who spent years on the prosecution side of DUI cases. He knows how prosecutors determine charging decisions, how they use sentencing guidelines to pressure plea bargains, and where there is room to fight for reduced charges or alternative sentencing. That prosecution experience is now the foundation of his defense practice.

Arizona’s DUI Classification System

Arizona law classifies DUI offenses into four tiers based on BAC level and circumstances. Each tier carries its own mandatory minimum penalties that judges cannot reduce below. Understanding which tier applies to your case is essential.

Standard DUI – A.R.S. § 28-1381

A standard DUI is charged when a driver is impaired to the slightest degree by alcohol or drugs under A.R.S. § 28-1381(A)(1), or has a BAC of 0.08 to 0.149 under A.R.S. § 28-1381(A)(2). This is a Class 1 misdemeanor.

Even at this lowest tier, Arizona mandates jail time. There is no option for a fine-only sentence on a standard DUI conviction. The judge must impose at least the mandatory minimum jail sentence.

Extreme DUI – A.R.S. § 28-1382(A)(1)

An extreme DUI is charged when the driver’s BAC is 0.15 or above but below 0.20. This is also a Class 1 misdemeanor, but the mandatory minimum penalties are significantly higher than a standard DUI. The legislature created this enhanced tier specifically to punish drivers with elevated BAC levels more severely.

Super Extreme DUI – A.R.S. § 28-1382(A)(2)

A super extreme DUI applies when the driver’s BAC is 0.20 or above. This remains a Class 1 misdemeanor but carries the harshest misdemeanor DUI penalties in Arizona law. The mandatory jail time, fines, and license consequences escalate dramatically at this level.

Aggravated DUI – A.R.S. § 28-1383

Aggravated DUI is a felony. It is charged when any of the following circumstances exist:

• The person commits a DUI while their license is suspended, canceled, revoked, or restricted due to a prior DUI offense
• The person commits a third DUI within 84 months (7 years) of two prior DUI convictions
• The person commits a DUI while an ignition interlock device is required on their vehicle
• The person commits a DUI with a passenger under 15 years old in the vehicle
• The person commits a DUI while driving the wrong way on a highway

Aggravated DUI is classified as a Class 4 felony (or Class 6 for wrong-way driving), and conviction carries mandatory prison time. Not jail. Prison. Under the Arizona Department of Corrections.

Understanding the Financial Penalties

The fines listed in Arizona DUI statutes are base fines only. The actual amount you pay is significantly higher once mandatory surcharges and assessments are added. Arizona imposes multiple surcharges on criminal fines that can double or triple the base amount.

The financial penalties for a DUI conviction include:

• Base fine – Set by the court within statutory guidelines
• Surcharges – Multiple state surcharges added as percentages of the base fine
• Prison construction assessment – $500 for DUI offenses
• DUI abatement fund – $500 minimum
• Public safety equipment fund – $20
• Probation surcharge – If probation is imposed
• Ignition interlock costs – $70-$150 per month for installation and monitoring, paid by the defendant
• Alcohol screening and treatment costs – $200-$2,000+ depending on the recommended treatment program
• License reinstatement fees – $100-$500
• SR-22 insurance – $25-$50 per month for 3 years, in addition to dramatically increased insurance premiums

When all costs are calculated, a first-offense standard DUI typically costs between $8,000 and $15,000 in total financial impact. A super extreme DUI or aggravated DUI can cost $20,000 to $150,000 or more when you include legal fees, lost wages from jail or prison time, and the long-term increase in insurance premiums.

Mandatory Minimum Sentences – What Judges Cannot Change

Arizona DUI law is built on mandatory minimums. Unlike many other criminal offenses where judges have broad discretion to fashion appropriate sentences, DUI sentencing constrains judicial discretion significantly.

Jail time is mandatory. A judge cannot sentence a DUI defendant to zero jail time for any DUI conviction. The minimum jail sentences described above are absolute floors. For extreme and super extreme DUI, the jail time must be served consecutively – meaning continuously, without work release or home detention during the mandatory minimum period.

Ignition interlock is mandatory. For every DUI conviction, Arizona requires installation of a certified ignition interlock device. The court cannot waive this requirement. The length varies by offense level and number of prior offenses.

Alcohol screening is mandatory. Every DUI defendant must complete an alcohol screening assessment, and the court must order any treatment recommended by the screening.

Fines are mandatory. The statutory minimum fines and assessments cannot be waived or reduced, though some judges have discretion to convert a portion of fines to community service in appropriate cases.

This mandatory minimum structure is precisely why the charging decision matters so much. The difference between a standard DUI and an extreme DUI is not just a label – it is the difference between one day of actual jail time and 30 consecutive days. The difference between a misdemeanor and an aggravated felony DUI is the difference between months in county jail and years in state prison.

How Prior Offenses Affect Sentencing

Arizona uses an 84-month (7-year) lookback period for DUI prior offenses. Any DUI conviction within the 84 months preceding the current offense counts as a prior for sentencing purposes.

The lookback period is calculated from the date of the prior offense to the date of the current offense, not from conviction date to conviction date. This distinction matters because DUI cases can take months to resolve. The date you were stopped and arrested is the date that counts.

What Counts as a Prior

The following count as prior DUI offenses for purposes of enhanced sentencing:

• Any DUI conviction under A.R.S. § 28-1381, § 28-1382, or § 28-1383
• DUI convictions from other states
• Convictions under local DUI ordinances
• Juvenile adjudications for DUI offenses in some circumstances

The Third Offense Trigger

A third DUI within 84 months automatically elevates the charge to aggravated DUI under A.R.S. § 28-1383, regardless of the BAC level. This means a driver who would otherwise face a standard misdemeanor DUI charge is instead facing a Class 4 felony with a presumptive prison sentence of 2.5 years.

---

Aggravated DUI – The Felony Tier

Aggravated DUI under A.R.S. § 28-1383 deserves special attention because the consequences are in a different category entirely.

Prison, Not Jail

Aggravated DUI convictions result in imprisonment in the Arizona Department of Corrections, not county jail. The sentencing ranges for a Class 4 felony are:

Category	Mitigated	Presumptive	Aggravated
No Prior Felonies	1.5 years	2.5 years	3.75 years
One Prior Felony	2.25 years	3.75 years	7.5 years
Two Prior Felonies	6 years	10 years	15 years

For wrong-way driving aggravated DUI (Class 6 felony):

Category	Mitigated	Presumptive	Aggravated
No Prior Felonies	0.5 years	1.5 years	2.75 years

Felony Record

A felony conviction follows you permanently. It affects employment opportunities, professional licensing, housing applications, firearm ownership rights, voting rights (until completion of sentence), and immigration status for non-citizens. Unlike misdemeanor DUI convictions, a felony aggravated DUI conviction cannot be easily set aside under Arizona law.

Mandatory Prison for Child Passengers

When an aggravated DUI is charged because a child under 15 was in the vehicle, Arizona law prohibits the judge from suspending the sentence or granting probation. Prison time is mandatory, not discretionary.

Sentencing Factors That Can Help or Hurt

While mandatory minimums constrain judges, there is still a range between the minimum and maximum sentence. Several factors influence where within that range a judge will sentence:

Mitigating Factors (Reducing Sentence)

• No prior criminal record
• Cooperation with law enforcement
• Acceptance of responsibility
• Enrollment in treatment before sentencing
• Stable employment and community ties
• Support of family members
• Low BAC (for standard DUI)
• No accident or danger to others

Aggravating Factors (Increasing Sentence)

• High BAC level
• Prior DUI history (even outside the 84-month window)
• Accident causing property damage or injury
• Excessive speed or reckless driving behavior
• Children in the vehicle
• Driving on a suspended license
• Refusal of chemical testing
• Lack of remorse or acceptance of responsibility

Why the Charging Decision Is the Real Battle

Understanding penalties is important, but the most critical moment in a DUI case often occurs before sentencing – at the charging stage. The difference between standard and extreme DUI, between misdemeanor and felony, is where the real fight happens.

Brad Rideout is a former Arizona prosecutor who made these charging decisions. He knows the criteria prosecutors use, the evidence thresholds they apply, and the negotiation dynamics that determine whether a case is charged as a standard DUI or an extreme DUI. He knows when a prosecutor’s case is strong enough to support the higher charge and when it is not.

That prosecution experience translates directly into more effective defense. When your attorney knows the charging playbook from the inside, they can identify weaknesses in the prosecution’s case that defense-only attorneys might miss.

Frequently Asked Questions

Can a DUI be expunged from my record in Arizona?

Arizona does not have true expungement for DUI convictions. However, Arizona’s “set aside” process under A.R.S. § 13-905 allows defendants who have completed their sentence to petition the court to set aside the judgment of guilt. A set aside does not erase the conviction, but it notes on the record that the case has been dismissed. This can be helpful for employment purposes. Note that felony aggravated DUI convictions face additional restrictions on set-aside eligibility.

Is home detention available instead of jail for a DUI?

For standard DUI first offenses, some courts allow home detention or work release for the jail time that exceeds the mandatory minimum. However, for extreme and super extreme DUI, the mandatory minimum jail days must be served consecutively in custody. Home detention may be available for days above the mandatory minimum in some jurisdictions.

Can I avoid an ignition interlock device?

No. Arizona law mandates ignition interlock installation for all DUI convictions. The court cannot waive this requirement. The minimum interlock period is 12 months for a first-offense standard or extreme DUI, 18 months for a first-offense super extreme DUI, and longer for second or subsequent offenses.

What happens if I violate probation on a DUI?

Probation violations can result in the imposition of any sentence the judge could have originally imposed, up to the statutory maximum. For a Class 1 misdemeanor DUI, that means up to 6 months in jail. For a felony aggravated DUI, it means up to the aggravated prison term. Judges take probation violations seriously in DUI cases.

Does a DUI affect my immigration status?

A DUI conviction can affect immigration status depending on the specific circumstances. While a single misdemeanor DUI is generally not considered a deportable offense, aggravated DUI (felony), DUI with a controlled substance, or multiple DUI convictions can trigger immigration consequences including inadmissibility, deportation proceedings, or denial of naturalization. Non-citizens facing DUI charges should consult with both a criminal defense attorney and an immigration attorney.

How long does a DUI stay on my driving record in Arizona?

A DUI conviction remains on your Arizona driving record permanently. The MVD does not remove DUI convictions from driving records. The 84-month lookback period applies only to enhanced sentencing for subsequent DUI charges – it does not mean the conviction disappears from your record after 7 years.

Can I get a restricted license during a DUI suspension?

For first-offense misdemeanor DUI, after the first 30 days of a 90-day suspension, you may be eligible for a restricted license that allows driving to work, school, and court-ordered programs if you have installed an ignition interlock device. For felony aggravated DUI, the license revocation is typically one year with no restricted license available.

Fight the Charge, Not Just the Sentence

The best time to reduce a DUI sentence is before conviction – by fighting to reduce or dismiss the charges themselves. Every day of mandatory jail time, every dollar of mandatory fines, and every month of ignition interlock is tied to the specific charge. Change the charge, and you change the sentence.
