Super Extreme DUI Charges in Lake Havasu?
The Test Result Is Not the Whole Case.
Super extreme DUI is the top tier of ARS 28-1382 and applies at an alcohol concentration of 0.20 or more within two hours of driving. It carries the longest jail term, the highest fines, and the longest interlock requirement of any misdemeanor DUI in Arizona.
Forty-five consecutive days in jail. That is what Arizona requires for a first-offense Super Extreme DUI, and it is more mandatory jail than most states impose for a third offense. Under ARS 28-1382(A)(2), a blood alcohol concentration of 0.20 or higher triggers the state’s most severe misdemeanor penalty, and no judge in Mohave County has the authority to hand down less.
The one lever that exists is the ignition interlock provision. Installing a certified device for 12 months allows a court to suspend all but 14 days. That is the difference between six weeks in the Mohave County jail and two weeks, and securing it requires a defense attorney who knows how the local courts approach these requests.

Understanding the arrest usually starts with understanding the day. A 0.20 sounds like extraordinary drinking. On the water in Arizona in July, it frequently is not.
Alcohol consumed over hours in extreme heat, with significant dehydration and little food, produces higher readings than the same drinks at home. People underestimate intake during a long day, lose track across a boat and a bar and a rental, and stop drinking well before driving without realizing their level is still climbing. Then they get stopped on Highway 95 at 9 p.m. and test at 0.21.
None of that is a legal excuse. But the physiology behind it matters enormously to the defense, because it goes directly to the two-hour window and the rising BAC analysis.
| Penalty | Requirement |
| Jail | 45 consecutive days, reducible to 14 with a 12-month ignition interlock |
| Base fine | $500 minimum plus surcharges |
| Prison construction assessment | $1,000 |
| Jail costs | Paid by the defendant |
| License suspension | 90 days |
| Ignition interlock | 18 months after reinstatement under MVD rules |
| Alcohol screening and treatment | Mandatory |
| SR-22 insurance | 3 years |
A second Super Extreme DUI, or one with any prior DUI within 84 months, brings 180 days in jail with 90 served consecutively, a 12-month license revocation, and a 24-month interlock requirement. Total costs across a first-offense case routinely exceed $5,000 and often reach five figures once lost income is counted.
When the state charges Super Extreme DUI, it almost always charges standard DUI and Extreme DUI as lesser included offenses in the same complaint.
This matters strategically. Defeating the 0.20 reading does not end the case; it moves the case down a tier. Pushing a 0.20 to 0.19 converts a 45-day minimum into a 30-day minimum. Pushing below 0.15 converts it into a 10-day minimum. Each step is worth weeks of a client’s life, which is why BAC challenges remain the highest-value work in these cases even when a complete dismissal is unlikely.
Lake Havasu City houses its municipal court, justice court, and a Mohave County Superior Court location together in a single facility.
Lake Havasu City sits in Mohave County, and felony matters go to Mohave County Superior Court rather than to any separate city courthouse. Which court and which prosecutor you are in front of shapes what interlock reduction and plea outcomes are realistically available.
The statute permits a court to suspend all but 14 days if the defendant installs a certified ignition interlock and complies with the applicable requirements. Permits, not requires.
At the Super Extreme level, judges frequently attach conditions before granting the reduction: completing an alcohol screening and any recommended treatment before sentencing, demonstrating a period of documented sobriety, agreeing to continuous alcohol monitoring, or installing the device early rather than after conviction. Building that record ahead of sentencing, rather than asking at the hearing, is a substantial part of what defense counsel does in these cases.
At 0.20 and above, several forensic issues become more pronounced rather than less.
Breath instrument margin of error. A reading of 0.21 sits within range of the Extreme tier once the instrument’s inherent error is accounted for.
Blood sample fermentation. Samples stored without adequate preservative or refrigeration can generate additional alcohol after collection, and this artifact is more significant at higher concentrations.
The two-hour window. Arizona requires the concentration to reflect the level within two hours of driving. In Mohave County, a highway stop can mean substantial transport time before a blood draw or a station breath test, which widens the gap between driving and testing.
Rising BAC. A person who drank heavily shortly before driving may still have been absorbing when tested, meaning the driving-time concentration was lower than the number on the report.
Observation period. The continuous 15-minute observation before a breath test is frequently compressed during high-volume holiday enforcement, and any burping or regurgitation during that window can introduce mouth alcohol.
Lake Havasu City Police, the Mohave County Sheriff’s Office, and Arizona DPS all make DUI arrests here, with jurisdiction depending on location. Enforcement surges over spring break, Memorial Day, the Fourth of July, and Labor Day, when officers work extended shifts and process arrests in volume.
That volume creates defense opportunities. Calibration and maintenance documentation, observation period compliance, chain of custody across agency handoffs, and consistency between body camera footage and the written report are all more likely to show problems during surge periods than during routine patrol.
Arrests on the water fall under Operating Under the Influence, enforced by Arizona Game and Fish, which carries different elements including the requirement that the vessel was underway.
The criminal case and the license case are separate. You have 15 days from service to request a hearing with the Arizona Motor Vehicle Division. If you do not, the suspension takes effect automatically regardless of how the criminal case turns out. Out-of-state drivers face this deadline too, and Arizona reports the outcome to your home state through the Driver License Compact.
Super Extreme DUI carries Arizona’s harshest misdemeanor sentence, and the defense work that matters happens early: independent review of the breath or blood evidence, building the record for an interlock reduction, and preserving the MVD hearing. Six weeks in jail and two weeks are both possible outcomes from the same arrest.
