If you have been arrested for a DUI in Scottsdale and your blood alcohol concentration (BAC) was measured at 0.15 percent or higher, you are likely facing a charge more serious than a standard DUI. Arizona law creates a distinct category for high-BAC drunk driving called “Extreme DUI,” and it carries significantly harsher penalties than a regular first-offense DUI. Understanding what sets this charge apart and what defense options exist, is essential for anyone facing this situation in Maricopa County.
What Is an Extreme DUI Under Arizona Law?
Arizona Revised Statutes § 28-1382 defines Extreme DUI as operating or being in actual physical control of a vehicle while having a BAC of 0.15 percent or greater within two hours of driving. The statute creates two sub-tiers:
- Extreme DUI: BAC between 0.15% and 0.199%
- Super Extreme DUI: BAC of 0.20% or higher
Both are charged as misdemeanors for a first offense, but the mandatory minimum penalties are far more severe than a standard DUI (which applies at BAC 0.08% or above). Arizona is one of the strictest states in the country when it comes to DUI enforcement. According to the National Highway Traffic Safety Administration (NHTSA), Arizona consistently ranks among the top states for DUI arrest rates per capita.
Extreme DUI Penalties in Arizona: First Offense
A first-offense Extreme DUI in Arizona carries the following mandatory minimum penalties:
- 30 consecutive days in jail (none of which can be suspended, and none can be served on home detention)
- Minimum fines and surcharges exceeding $2,500
- Alcohol screening and education or treatment
- License suspension of 90 days
- Ignition Interlock Device (IID) required on all vehicles driven for 12 months after license reinstatement
- Traffic Survival School
Compare this to a standard first-offense DUI, which carries a minimum of 10 days in jail (9 of which can be suspended upon completion of treatment), and minimum fines of approximately $1,500. The Extreme DUI designation roughly doubles the floor on penalties.
Super Extreme DUI Penalties: First Offense
If your BAC was 0.20 percent or higher, you face Arizona’s Super Extreme DUI designation. Penalties include:
- 45 consecutive days in jail; mandatory, none suspended
- Minimum fines and surcharges exceeding $3,250
- 18-month ignition interlock requirement
- License suspension
- Mandatory alcohol treatment
These are minimum thresholds. Judges have discretion to impose additional jail time, extended supervision periods, and higher fines, especially if aggravating factors such as speeding, an accident, or a prior offense are present.
Second-Offense Extreme DUI: Felony Territory
A second Extreme DUI within 84 months (seven years) dramatically escalates the consequences. Penalties can include 120 days or more in jail, license revocation for one year, dramatically increased fines, and a permanent criminal record entry that employers, landlords, and licensing boards can see. In some circumstances, a second DUI within seven years with a BAC above 0.15 can form the basis for an Aggravated DUI charge, a Class 4 felony.
How an Extreme DUI Is Proven in Court
Prosecutors in Maricopa County typically rely on two types of BAC evidence:
Breath Testing (Intoxilyzer 9000): Arizona law enforcement primarily uses the Intoxilyzer 9000, a breath testing instrument that must be calibrated and maintained according to strict protocols. Malfunctions, improper calibration records, and operator error can all affect the reliability of results.
Blood Testing: Blood draws provide more accurate BAC measurements but are subject to chain-of-custody challenges, improper storage issues, and laboratory protocol compliance. Fermentation in improperly stored blood samples can cause BAC readings to rise after the draw.
Both methods have vulnerabilities that an experienced defense attorney can probe.
Defense Strategies for Extreme DUI in Scottsdale
Even with a high BAC reading, a skilled defense attorney has several avenues to challenge an Extreme DUI charge:
- Challenging the legality of the traffic stop (was there reasonable suspicion?)
- Challenging field sobriety test administration (NHTSA-standardized procedures must be followed exactly)
- Attacking the calibration and maintenance records of the breathalyzer
- Challenging blood draw procedures and chain of custody
- Arguing rising BAC, that your BAC was below 0.15 at the time of driving, but rose to an extreme level by the time it was measured
- Challenging the two-hour window required by the statute
An experienced Scottsdale extreme DUI defense attorney will analyze every step of the DUI investigation, from the initial stop to the blood or breath test, to identify weaknesses in the prosecution’s evidence. In some cases, charges can be reduced to a standard DUI, significantly lowering the mandatory minimums. In others, suppression of key evidence can result in dismissal.
Frequently Asked Questions About Extreme DUI in Scottsdale
Can I refuse a breath or blood test?
Arizona’s implied consent law (A.R.S. § 28-1321) means that by driving in Arizona, you have already consented to chemical testing if lawfully arrested for DUI. Refusal results in an automatic 12-month license suspension for a first refusal and 24 months for a second. However, refusal does not prevent prosecution, police can obtain a search warrant for a blood draw.
Will I lose my license immediately after an Extreme DUI arrest?
The Arizona Motor Vehicle Division (MVD) will administratively suspend your license within 15 days of your arrest notice. You have 15 days from the date of the notice to request a hearing to contest the suspension. Miss that window, and the suspension becomes automatic.
Can an Extreme DUI be expunged in Arizona?
Arizona does not have traditional expungement, but a 2023 law (A.R.S. § 13-911) allows for the sealing of certain criminal records. Most DUI convictions are eligible for sealing after a three-year waiting period from the completion of the sentence, though sealed records can still be seen in some law enforcement and licensing contexts.
