Attorneys Have to Carefully Choose When to Argue Certain Defenses

As an attorney, you really need to be careful in making certain arguments. The wrong facts in a case can destroy an argument for years to come. You do not want to go to a court or field with the wrong facts because it can harm its future use by attorneys who have the right facts.

You need to be careful on when you argue it, and how you argue it. There are a lot of cases where you are just waiting for the right facts to make the right arguments and hopefully, from that make good case laws.

How Do the Police React to a Recommendation for Marijuana?

Interviewer: When you see clients being pulled over and they have medical marijuana recommendation, and the police see that, what usually occurs next? Do the officers definitely try to arrest them for DUI or do they heed the medical recommendation?

Brian: They make take notes that they believe this person is under the influence of marijuana. They will take notes that someone has a medical marijuana card. I have only seen one client that has a active valid medical marijuana card that was arrested for DUI and that was because there was also alcohol involved  and because they were going on a theory of impairment.

That client was not charged with having any drug or metabolite in her system even though she did have marijuana in our system. The problem is that it’s similar to alcohol. Alcohol is legal. You are supposedly allowed to consume it and then drive a vehicle.

It Is Difficult to Distinguish When a Legally Approved Substance Causes Impairment

It’s only that at some point, alcohol impairs your ability to drive even to the slightest degree. Even though it’s legal, even though you can use it, there’s a fine line between using it and driving, and not being impaired and using it and driving and being impaired.

When Judging Alcohol Impairment, There Are Established Levels for When You Are Not Impaired and When You Are Impaired

At least with alcohol, we have legal presumptions. If you are between a 0.00 and 0.39, you are presumed to not be impaired. If you are at a level of 0.4 and a 0.079, there’s no presumption as to whether you’re impaired or not.

If you are at a 0.08 or above, you are legally, statutorily presumed to be impaired.

“I am one of only a handful of Phoenix DUI Lawyers that focuses solely on DUI Defense representation.”

I have spent my entire career SOLELY focused on Arizona DUI Defense Representation, having personally defended more than 4,400 Driving Under the Influence (DUI) clients in the past 19+ years.

If you’re looking for a Divorce Attorney, Tax Attorney, Civil Attorney, etc., I can comfortably say, "I’m not the one for you." I ONLY defend DUI cases in most of Maricopa County, Arizona.

Coming up with traditional, as well as outside-the-box motions and defenses for my clients, often with good results, is the hallmark of my practice.

Lawyers that say they are "aggressive" or "will fight for you" are a dime a dozen. They use these phrases because it is a proven advertising phrase. Being "aggressive" isn’t the same as being good, and is often used to put on a show to hide the fact that they aren’t doing anything meaningful for the client.

The same is true for the Lawyers claiming to do DUI Defense, and Criminal Cases, and Accident Cases, and Divorces, etc. A Jack-of-all-Trades is a master of none! By handling all sorts of cases, they take away from their ability to truly focus on DUIs, and keep up-to-date on the latest changes in DUI Defense Representation.

What I offer is intelligent, quality DUI Defense at an exceptional price. Unlike many other law firms, if you hire The Law Offices of Brian D. Sloan, you actually get me representing you, doing all the work, and working the case. You aren’t hiring one guy with all the experience, but getting the underling with very little knowledge or experience.

I work seven days a week on my client’s cases, and spend hours laying all my thoughts out for my clients in writing, so they can understand their options, and my recommendations. No other DUI Lawyer in the state does this. I try to do what I can to go above-and-beyond for my clients. I hate when the businesses I deal with nickel-and-dime me with hidden costs, and I take pride in not doing that to my clients.

I have not only taught other lawyers how to do DUI Defense Representation at statewide seminars, but I have produced DUI Legal Guides used by defense lawyers across Arizona.

I am one of Arizona's most award-winning DUI Defense Lawyers, as well as being recognized nationally. I was the only DUI Defense Lawyer in the United States named a "Power Lawyer" in a 2022 issue of USA Today

There are no other private Lawyers in Arizona that have personally defended more DUI cases than I have. And as a bonus, I offer a very reasonable flat rate for my legal services, with a payment plan, and without any hidden charges. This guarantees that I offer some of the most competitive rates among all Arizona DUI Attorneys, while being a well-documented and preeminent leader in the field of DUI Defense Representation.

Over the years, countless people have come to me after discovering that their first lawyer made a mistake, gave them false hope or false promises, or simply took their money and didn't do much to advance their case. And you would be surprised at how often this happens.

So, instead of wasting time and money on the wrong DUI Defense Attorney, do yourself a favor and get the proven and well-recognized best DUI Lawyer in Phoenix and the surrounding areas of Maricopa County.

You can reach me on my personal cell phone at 480-720-7839 for a Free ‘In Depth’ Consultation.

I personally defend DUI cases in urban Maricopa County City, Town, and Justice Courts, including:

Ahwatukee / Agua Fria / Arcadia Biltmore / Avondale / Buckeye / Chandler / Country Meadows / Desert Ridge / Dreamy Draw / Downtown / East Mesa / El Centro / Encanto / Gilbert / Glendale / Goodyear / Guadalupe / Highland / Kyrene / Litchfield Park / Maryvale / McDowell Mountain / Mesa / Moon Valley / North Mesa / Peoria / Phoenix / Queen Creek / San Marcos / San Tan / South Mountain / Scottsdale / Tempe / University Lakes / West McDowell / West Mesa / White Tank

For any other Courts in the State of Arizona, including Felony cases, I would recommend my associates on The Arizona DUI Team, whom I work closely with, but I am not the one personally representing the client.
