DUI Sobriety Checkpoints In Arizona

DUI or sobriety checkpoints, also referred to as mobile checkpoints or roadblocks, are permitted in Arizona. They refer to police traffic stops that are not tied to any specific or individual suspicions. They may be set up at a random location for a short period of time at a chosen location in order to stop and identify motorists who may be driving under the influence of alcohol or other controlled substances. These checkpoints also help identify other traffic offenders or violators, such as those driving on a suspended license, or those driving without a valid license.

Based on estimates, the average cost of conducting a DUI checkpoint in Arizona is approximately $8,900 per checkpoint. Estimates also show that the state of Arizona saves approximately $62,500 per checkpoint when it comes to police resources, cost of travel delays, and the value of mobility losses as a result of impaired drivers apprehended and sanctioned.

What Happens At A Sobriety Checkpoint?

Drivers passing through a sobriety checkpoint are briefly detained and interviewed. The officer will ask then to roll down their window and answer some basic questions. Drivers will also be asked for their driver’s license, registration, and proof of car insurance. The officer will also ask them where they are coming from and where are they headed.

The officer will usually look for signs of intoxication, such as if the driver smelled of alcohol, has bloodshot eyes, has a flushed face, has slurred speech, or is showing lack of coordination. If the officer suspects that the driver is under the influence, they will ask them whether they have been drinking. The driver will be instructed to move their vehicle to the side of the road and step out of the car. The officer will also issue standard field sobriety tests or do a breathalyzer test using a handheld breathalyzer.

The goal of these checkpoints is to identify drunk and intoxicated drivers and to keep them off the roads. Based on statistics provided by the CDC (Center for Disease Control and Prevention), sobriety checkpoints have the potential to prevent approximately 1 out of 10 DUI-related deaths.

Police Need Probable Cause To Arrest Someone In Arizona

In Arizona as well as in other states, police need probable cause to stop someone and interrogate them. However, sobriety checkpoints are an exception to the search and seizure provisions of the U.S. Constitution. Moreover, the U.S. Supreme Court has ruled that the “degree of intrusion” of sobriety checkpoints are outweighed by the dangers of drunk driving.

The National Highway Safety Transportation Board has issued guidelines for police officers when administering sobriety checkpoints. The first and the most important guideline is that police must publicize the checkpoints ahead of time. If you have been stopped at a DUI sobriety checkpoint in Arizona and are facing drunk driving charges, you need to get in touch with a DUI defense attorney.

“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.
