THE NEW ARIZONA DUI LAWS ARE HERE!
Posted on May 08, 2011It's true - Arizona has reduced the penalties for DUI convictions. Here are some of the highlights: The interlock requirement has been reduced from 12 months to 6 months (for first time non-extreme DUI.) The mandatory jail requirements have been modified / reduced...
Blood Testing Is About More Than A Machine
Posted on February 05, 2011In DUI cases, an accurate blood test result requires more than just the blood tester to be working properly. A reliable test results requires more than than what the machine (the blood tester) provides. As shown below, see the machine is just a fraction of the process need to obtain an accurate and reliable result...
Interview with KTAR's Jay Lawrence
Posted on October 26, 2010This past Sunday I was interviewed by local radio station KTAR's Jay Lawrence on a number of Arizona DUI issues, including: current Arizona charges and penalties, changing enforcement standards for DUI charges based on jurisdiction (Scottsdale, for example), measurement and testing, drug-based DUI charges - both legal prescription and illegal, differing charges while a child is in a vehicle, and timelines for resolution of DUI charges...
The Dirty Little Secret (of Arizona DUI First Offense)
Posted on August 25, 2010Here is the math used in Arizona: INCREASED JAIL + DUI PROBLEM = REDUCED DUI PROBLEM. It makes perfect sense, right. Who would risk more than a month in jail for a few drinks. Apparently - lots of people. Maybe even more people now, than when the penalties were previously lower...
The DUI With No Driving - Part 1
Posted on July 21, 2010DUI stands for driving under the influence. However, years ago Arizona, like many other states, changed its DUI laws to cover situations where the person was not actually driving. Instead, to be guilty of DUI, a person just needed to be "controlling" a vehicle...
Scottsdale DUI: Home Detention Is Here (Almost)
Posted on July 09, 2010I was in the Scottsdale City Court yesterday when I heard a Judge discussing the much anticipated Home Detention Program. It appears that they have finally implemented the program. Here are the minimum qualifications based on the information I was given at court...
Scottsdale DUI: Home Detention Update
Posted on June 10, 2010While the City of Scottsdale has approved a home detention program, it has not released any of the program's details. The most anticipated detail is the start date. As of yesterday, the start date has not been released. There has been speculation that it may not start until the end of summer...

Best DUI Blog Posts: December 2009
Posted on December 16, 2009I am starting a new list of the best DUI blog posts for the past month. I am admittedly stealing the idea after reading Kevin O'Keefe's Best In Law Blogs. However, as I am one of Kevin's clients, I don't think he will mind (as long as the check clears...
When Lawyers Attack
Posted on December 15, 2009Last night I am reading Gideon's blog and I see a post with the title: 'This Seattle DUI lawyer is a Douchebag.' As someone who loves a good fight, I started reading. Here is the beginning of the post: So normally I don't write posts like this, because I don't give flyin' rat's ass...
Arizona Extreme DUI: The Out of State Visitor Dilemma
Posted on November 18, 2009The harsh penalties for an Arizona extreme DUI conviction have been well chronicled in this blog. However, what happens when we apply these penalties to people who were only visiting Arizona and charged with DUI? One could take the view: who cares? When people come to "our state" and commit crimes, they deserve whatever they get...
How accurate is blood testing for alcohol?
Posted on October 28, 2009The truth of the matter is we don't really know. Most labs in the Phoenix Arizona area claim to be accurate within 5%. That means if your blood result came back at .08, then the true result can be anywhere from 5% lower or 5% higher. Other scientific organizations claim 5% is not a realistic range of accuracy...
No Consent, No Warrant, No Blood
Posted on September 04, 2009Some things in life seem obvious. It is hotter in the summer. It is colder in the winter. The government must get a warrant to stick a needle in your arm before they forcibly take your blood. However, this last presumption has not been so obvious in Arizona...
5 Things You Should Know About Arizona Super Extreme DUI Convictions
Posted on July 30, 2009Arizona is one of a few states that has created something referred to as "Super Extreme DUI." A DUI is "Super Extreme" if a person's blood alcohol concentration is .200 or above. While this crime is still a misdemeanor, it carries a minimum jail term that is greater than most first time felonies...
What Do Field Sobriety Tests Prove?
Posted on June 29, 2009The short answer is not much. At best, they may correlate to someone having a blood alcohol concentration over a .08. At worst, they prove nothing at all. To understand their meaning you must look at how they came into existence and who developed them...
A Person Accused Of DUI Deserves A True Second Opinion
Posted on June 15, 2009Arizona DUI cases almost always involve a chemical test. There is a movement in Arizona towards the exclusive use of blood testing. It is well settled that blood testing is more accurate than breath testing. But how accurate is blood testing? Can it truly determine a person blood alcohol concentration? I believe that these are reasonable questions to be asked by a person accused of DUI and facing 30 to 45 days in jail...
A Well Written Post on The Source Code Issue
Posted on January 26, 2009I ran across an excellent post discussing the source code issue. That is, the fight between criminal defense attorneys and the maker of the breath tester (CMI) to disclose the code used in their breath testers. CMI will not allow an inspection of the code...

Wonder Bread Does it Again!
Posted on December 15, 2008It turns out my previous post showing Wonder Bread causing a false blood alcohol concentration reading was not an isolated incident. The same forensic toxicologist and drug recognition expert did another Wonder Bread experiment. Here it is:
Can Bread Cause the Intoxilyzer to Give a False Reading?
Posted on December 06, 2008As demonstrated below, it appears that Wonder Bread is like Kryptonite to the Intoxilyzer 8000. While I cannot guarantee the accuracy of the test that occurred in this video, I have very little reason to doubt its veracity. Especially since the manufacture of the Intoxilyzer 8000 (CMI) will not allow anyone (including the government) to inspect the source code used in this contraption...
