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 focused on DUI Defense representation, having personally defended more than 4,100+ DUI clients in the past 18+ years.

If you’re looking for a divorce attorney, tax attorney, or civil attorney, then I can comfortably say: "I’m not the one for you".

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 that is what they think people want to hear. The truth of the matter is, being "aggressive" rarely gets the client anywhere in these court systems. Being "aggressive" isn’t the same as being good, and is often used to put on a show for a client to hide the fact that they aren’t doing anything meaningful for the client.

The same is true for the lawyers that claim to do DUI Defense... and Criminal Cases..., and Accident cases..., and Divorces. A Jack-of-all-Trades is a master of none. By handling all different 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.

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

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

I am one of the most award-winning DUI Defense Lawyers in Arizona; have been recognized nationally, including in a 2022 issue of USA Today; and there are only a few lawyers in Arizona who have personally defended more DUI cases than I have. I am also one of the most reasonably-priced DUI Lawyers, as I pride myself on charging a Flat Rate only for the legal services you need, and not for the legal services you don’t.

I am also the lawyer who people call once they realize that their original lawyer screwed something up, gave them false hope or false promises, or simply just took their money and didn’t do much on the case. You would be surprised at how often this happens.

Save yourself the trouble of hiring the wrong lawyer, and hire the right DUI Defense Lawyer from the start.

You can reach me on my personal cell phone: 480-720-7839.

Let me know if you have any questions!
