The flashing lights in the mirror were the easy part. What happens in the next few minutes, and over the next 30 days, will shape your options in ways most drivers don’t fully grasp until it’s too late. The moment an officer pulls you over on suspicion of DUI in Phoenix, two separate clocks start running: the criminal case and the license suspension. Missing a deadline on either one can close doors that can’t be reopened.
I founded The Koplow Law Firm in 2005 after prosecuting DUI cases for the Maricopa County Attorney’s Office, including time in its Vehicular Crimes Unit. I’ve sat on both sides of these cases. That background shapes how I read an arrest report, how I evaluate a chemical test result, and how I spot the places where a stop or a subsequent arrest didn’t go the way the law requires. What follows is what I tell people who call me right after a DUI stop in Phoenix.
What Happens in the First Few Minutes of the Stop
Arizona law requires a driver to provide a name, driver’s license, vehicle registration, and proof of insurance. That’s it. You have the right to remain silent about where you were coming from, whether you had anything to drink, or how much. Answering those questions doesn’t help you. It gives the officer language for an arrest report that becomes part of the state’s case against you.
The roadside tests most people associate with a DUI stop, including the walk-and-turn, the one-leg stand, and the horizontal gaze nystagmus test (which measures involuntary eye movement the officer associates with alcohol impairment), are voluntary in Arizona. Declining them doesn’t trigger a license suspension. A refusal can be referenced at trial, but that’s a very different consequence than the suspension that follows a post-arrest chemical test refusal. Field sobriety performance is also influenced by age, footwear, road surface, medical conditions, and anxiety. Officers aren’t always trained to account for those factors.
Underneath all of this sits a constitutional framework that matters to your defense. An officer needs reasonable suspicion to make the stop and probable cause to make an arrest. Whether the officer actually met those standards is frequently where a defense finds its opening.
The Test Request: Why the Answer Changes Everything
Arizona’s implied consent law, codified at A.R.S. § 28-1321, means that by driving in Arizona, you’ve already consented to a chemical test of your breath, blood, or urine if you’re lawfully arrested on suspicion of DUI. That request comes after an arrest, not during the roadside investigation. These are two distinct moments, and the consequences attached to each are completely different.
If you submit to testing and your blood alcohol concentration registers at or above the legal limit, the Admin Per Se suspension under A.R.S. § 28-1385 takes effect: 90 days for a first offense, with restricted-driving eligibility available after the first 30 days. During those initial 30 days, you can’t drive at all unless you obtain a Special Ignition Interlock Restricted Driver License, which comes with its own requirements and fees.
If you refuse the chemical test, the Implied Consent suspension is longer and harsher: 12 months for a first refusal, or 24 months if you’ve had a prior refusal within the last 84 months. That suspension runs regardless of whether the DUI charge is ever proven in court. Refusal also eliminates the possibility of a restricted license during the suspension period. The test-or-refuse decision carries real weight, and it’s made in a high-stress moment with no time to think it through. Understanding these consequences now (before you’re ever in that situation) is the point.
The 30-Day Window Most Drivers Don’t Know About
When you receive a suspension notice from the Arizona Motor Vehicle Division, a 30-day clock starts. You have 30 days from the date on that notice to request an MVD executive hearing to challenge the suspension. Miss that window and the suspension can’t be challenged administratively. It proceeds on its own track, separate from anything happening in criminal court, and there’s no way to get that hearing back. Requesting the hearing on time pauses the suspension until a decision is reached. That matters enormously for people who drive for work or need a vehicle to manage daily life.
Several sources online still cite a 15-day deadline for this hearing request. That figure is outdated. The date on your specific suspension notice controls your deadline, which is one more reason to review your paperwork with an attorney immediately rather than rely on general information you find online.
The license track runs entirely separately from the criminal case. Most first and second Phoenix DUI arrests that rise to the level of misdemeanor charges are handled at Phoenix Municipal Court, located at 300 W. Washington St. That court processes cases up to Class 1 misdemeanors, which carry a maximum of six months in jail and a $2,500 fine. If your charges are aggravated or involve a felony, the case moves to Maricopa County Superior Court’s Criminal Department, heard primarily at the Central Court Building at 201 W. Jefferson St. and the South Court Tower at 175 W. Madison St. Knowing which court handles your case tells you what the procedural timeline actually looks like and what’s at stake on the criminal side.
What to Do Before You Talk to Anyone Else
Memory degrades fast, especially after a stressful experience. Before you call a friend or post anything online, write down everything you remember: the sequence of events from the moment you saw the lights, any medications you took that day, any physical conditions that might have affected your balance or eye movement during field sobriety testing, road conditions, lighting, and what the officer said and when. That record isn’t just useful for you. It’s material I can use to examine whether the tests were administered correctly and whether the officer’s observations hold up.
Don’t discuss the stop or the arrest with anyone other than your attorney. Statements made to friends, family, or on social media can surface in the criminal case or in the MVD hearing. The same goes for text messages sent in the hours after the stop. Keep all the paperwork together as well. The citation, the suspension notice, and any temporary permit you received at the time of the stop each carry deadlines or reference numbers that matter.
Two Clocks, One Window to Act
The choices made in the first hour after a DUI stop, and the steps taken within the first 30 days, determine what options remain further down the road. The suspension clock doesn’t wait for the criminal case to resolve, and both tracks demand attention at the same time.
I’ve defended DUI cases in Phoenix and across Arizona since 2005, and before that I prosecuted them for the Maricopa County Attorney’s Office. I know how these cases are built, where they can be challenged, and what the deadlines actually require. If you’ve just been through a DUI stop, I’m available around the clock and offer free consultations, including virtual meetings for people who need flexibility.
