What you need to know
If you’ve been arrested for DUI in Arizona, you may be wondering what kind of charge you’re facing. In many cases, a DUI is classified as a Class 1 misdemeanor, which is the most serious type of misdemeanor under Arizona law. But not all DUIs are created equal—and understanding the differences can impact your case and your future.
At Rideout Law Group, our experienced Scottsdale DUI attorneys help clients across Maricopa County fight DUI charges, protect their licenses, and avoid jail time. Here’s what you need to know.
What Is a Class 1 Misdemeanor DUI in Arizona?
Under Arizona Revised Statutes §28-1381, a first-time DUI is typically charged as a Class 1 misdemeanor. This applies when:
- Your blood alcohol content (BAC) is 0.08% or higher (0.04% for commercial drivers)
- You’re driving while impaired to the slightest degree by alcohol, drugs, or a combination
- No one was injured, and no aggravating factors were present
A Class 1 misdemeanor is the most serious misdemeanor level in the state. While it’s not a felony, it carries hefty penalties, including:
- Up to 6 months in jail
- Fines and fees totaling $1,500+
- Alcohol screening and treatment
- Mandatory MVD license suspension
- Ignition interlock device installation
- Possible probation
Penalties for First-Time DUI in Arizona
Even a first-time Class 1 misdemeanor DUI can be life-changing. Arizona has some of the toughest DUI laws in the country, with mandatory minimum sentences and little room for leniency.
For example, a first offense generally requires:
- 10 consecutive days in jail (with up to 9 days suspended upon completion of alcohol education)
- $250 base fine (plus assessments and surcharges)
- License suspension for 90 days (or one year for refusal of a chemical test)
If your BAC is higher—above 0.15% (Extreme DUI) or 0.20% (Super Extreme DUI)—the penalties increase, but the charge may still remain a misdemeanor unless other factors apply.
When Does a DUI Become a Felony in Arizona?
A DUI becomes a felony (Class 4 or Class 6)—known as Aggravated DUI—when certain conditions are met:
- Third DUI within 7 years
- DUI while your license is suspended or revoked
- DUI with a child under 15 in the vehicle
- Refusal to install a court-ordered ignition interlock
These felony charges carry much harsher penalties, including up to 3.75 years in prison, longer license revocations, and lifelong consequences for housing, employment, and civil rights.
Legal Representation Makes the Difference
DUI charges in Arizona move quickly. You’ll face both criminal court proceedings and administrative license actions through the MVD. Having a skilled attorney early in your case can help you:
- Challenge the legality of the stop or arrest
- Review breathalyzer or blood test accuracy
- Fight for reduced charges or case dismissal
- Negotiate alternative sentencing (e.g., home detention)
At Rideout Law Group, we offer aggressive DUI defense tailored to your situation. Our attorneys understand Scottsdale courts, prosecutors, and diversion programs, giving our clients a strong local advantage.
