Being arrested for driving under the influence is a stressful and life-altering experience. If you are unsure what to do after a DUI arrest in Arizona, you are not alone. Arizona has some of the toughest DUI laws in the United States, and the actions you take immediately after your arrest can greatly affect your freedom, finances, and driving privileges.

This general guide explains the legal process, your rights, and the smartest steps to take after a DUI arrest anywhere in Arizona.

Understanding a DUI Arrest in Arizona

A DUI arrest in Arizona typically starts with a traffic stop by a local police officer, county sheriff, or state trooper. If the officer suspects impairment, they may conduct field sobriety tests or request a breath or blood test.

Under Arizona law, you can be arrested for:

• Driving with a BAC of 0.08% or higher

• Driving while impaired to the slightest degree

• Driving with drugs (prescription or illegal) in your system

• Extreme or aggravated DUI offenses

Knowing the seriousness of these charges is the foundation of understanding what to do after a DUI arrest in Arizona.

---

Step 1: Stay Calm and Protect Your Rights

After a DUI arrest, your behavior matters. Staying calm can prevent additional charges and complications.

Your Legal Rights

• You have the right to remain silent

• You have the right to an attorney

• You do not have to answer questions about drinking or drug use

Be respectful, but avoid volunteering information. Even casual comments can later be used as evidence.

---

Step 2: Know What Happens Immediately After the Arrest

A DUI arrest in Arizona triggers two separate legal actions:

1. A criminal court case

2. A driver’s license suspension process through the Motor Vehicle Division (MVD)

Many drivers are surprised to learn that the license suspension process begins even before a court conviction. This makes understanding what to do after a DUI arrest in Arizona extremely time-sensitive.

---

Step 3: Request an Arizona MVD Hearing Quickly

After most DUI arrests, you have 15 days to request a hearing with the Arizona Motor Vehicle Division.

Failing to request this hearing may result in:

• Automatic license suspension

• Loss of driving privileges for months or longer

Requesting a hearing may allow you to continue driving temporarily and gives your attorney an early opportunity to challenge the arrest.

---

Step 4: Write Down Everything You Remember

As soon as possible, document details such as:

• Where and why you were stopped

• What the officer said or asked

• Whether sobriety tests were explained clearly

• How chemical testing was conducted

Small details can become powerful defense tools later.

---

Step 5: Avoid Talking About Your DUI Case

One of the biggest mistakes people make after a DUI arrest is talking too freely.

• Do not post about the arrest on social media

• Avoid discussing details with coworkers or friends

• Only discuss your case with your attorney

Silence can protect you while your defense is being prepared.

---

Step 6: Contact an Experienced Arizona DUI Lawyer

Hiring a DUI defense attorney is one of the most important decisions you can make.

How a DUI Lawyer Can Help

• Review police reports and video footage

• Challenge breath or blood test accuracy

• Identify violations of your constitutional rights

• Negotiate reduced charges or penalties

Arizona DUI laws are complex, and legal guidance can significantly impact the outcome of your case.

---

Step 7: Prepare for the Arizona Court Process

A DUI case may involve:

• Arraignment

• Pretrial hearings

• Motion filings

• Trial or plea negotiations

Following your attorney’s advice, appearing in court on time, and taking the case seriously all work in your favor.

---

Possible Penalties for a DUI Conviction in Arizona

Depending on the facts of your case, penalties may include:

• Jail or prison time

• Fines and court costs

• Driver’s license suspension or revocation

• Mandatory DUI education or treatment

• Ignition interlock device installation

Arizona penalties increase quickly for high BAC levels or repeat offenses.

---

Common Mistakes to Avoid After a DUI Arrest

To protect yourself, avoid:

• Missing court dates or deadlines

• Ignoring MVD notices

• Talking to police without a lawyer

• Delaying legal representation

These mistakes can make a difficult situation much worse.

---

If you or a loved one is facing a DUI charge, taking informed action right away is the smartest step forward.

Why a bicycle or horse usually isn’t “DUI” in Arizona

Arizona’s DUI statute (A.R.S. § 28-1381) makes it illegal to drive or be in actual physical control of a vehicle while impaired. Under Title 28, a “vehicle” is a device used to transport people/property on a roadway but excludes devices moved by human power (like a standard bicycle). A horse is an animal—not a “device”—so it’s not a “vehicle” either.

Bottom line: Riding a human-powered bike or a horse while drunk typically does not meet the definition for DUI in Arizona.

⚠️ Exception: If you’re operating an animal-drawn carriage/cart, that device is a “vehicle.” DUI exposure can exist for the driver of the buggy/cart—not a person merely riding a horse.

---

What about e-bikes, e-scooters, mopeds & “whizzers”?

If it’s powered by a motor (gas or electric), it can fall within Arizona’s “vehicle” definition (even if it’s not a “motor vehicle”). That means DUI can apply to:

• Gas-assist bicycles / “whizzers”

• Many stand-up e-scooters

• Mopeds & motorized skateboards

• Mini-bikes, ATVs, UTVs, and of course cars/trucks

These cases often turn on the device’s specs (power, top speed, throttle/pedal-assist), where you were riding, and how the officer articulated “actual physical control.”

---

“So I’m safe on a bike/horse, right?” Not necessarily.

Even when DUI doesn’t apply, police can (and do) charge other offenses if your conduct is unsafe or disruptive, such as:

• Disorderly conduct (A.R.S. § 13-2904)

• Endangerment (A.R.S. § 13-1201)

• Criminal nuisance (A.R.S. § 13-2908)

• Obstructing a highway / traffic violations (Title 28)

• Animal-related offenses (if a horse is put at risk)

Arizona has no statewide “public intoxication” crime, but conduct-based charges still apply.

---

“Actual Physical Control” still matters

With motorized devices, you can face DUI even if you weren’t moving when contacted (e.g., straddling an e-scooter with the power on). The facts—location, keys/power state, impairment clues—decide APC.

---

Penalties if DUI applies to your motorized device

Arizona DUI penalties are harsh (jail, ignition interlock, license issues, fines, classes). Certain devices also trigger license suspensions and interlock. The exact outcome depends on BAC/BrAC, priors, and the device category.

---

Defenses we use in “bike/horse/e-scooter” cases

• Not a “vehicle” under Title 28 (human-powered bike, horse)

• Device classification (pedal-assist vs. throttle, power/speed limits)

• No actual physical control

• Illegal stop/seizure or bad field sobriety procedures

• Faulty breath/blood testing

• Body-cam/video contradictions

---

What to do after a stop or citation

1. Say you want a lawyer and remain polite & silent.

2. Don’t guess about your device’s classification on the roadside.

3. Write down details (location, device make/model, settings, names of witnesses).

4. Call Ted Law, Tempe: 602-453-3100.
