Casa Grande DUI Lawyer

Casa Grande is a Pinal County hub between Phoenix and Tucson. Interstate 10 and State Routes 287 and 387 connect the city with surrounding communities, so a DUI stop may occur on a local street, a commercial corridor, or a highway used for longer-distance travel. The Census Bureau estimated Casa Grande’s population at 68,927 in 2024, reflecting substantial growth since 2020.

The Casa Grande Police Department provides local policing, and Casa Grande Municipal Court handles cases within its jurisdiction. A DUI allegation arising outside city limits may be assigned to a different court, while felony charges may be handled by Pinal County Superior Court. Confirm the court and deadlines from the citation and any paperwork issued after the arrest.

For a Casa Grande DUI case, an attorney can examine the officer’s reason for the stop, observations of impairment, field sobriety exercises, and any breath or blood testing. On I-10 and other high-speed routes, records of the precise stop location and the sequence of events may help clarify the circumstances. The defense should also check whether testing and evidence documentation followed required procedures. Rosenstein Law Group helps clients understand the charge, court process, and available options.

What is an Arizona DUI Offense?

You can find Arizona’s DUI law in statute ARS 28-1381. This statute defines DUI in three ways:

• Driving or being in “actual physical control” of a motor vehicle while being under the influence of any type of intoxicating liquor, drug, or vapor-based toxic substance
• Driving or being in “actual physical control” of a vehicle with a BAC greater than .08%
• Driving or being in “actual physical control” of a vehicle with any impairing drug and/or its metabolite in your system.

What Does it Mean to Be Under the Influence of Alcohol or Drugs?

When you are pulled over or questioned by the Casa Grande police, the officer will try to get you to agree to give a breath or blood sample to measure your blood alcohol concentration (BAC). If you provide such a sample and it returns a BAC level of 0.08 percent or more, you will be presumed to be impaired by alcohol. 

If a non-alcoholic drug is affecting your driving, its presence in your system qualifies as being under the influence, including medications a licensed physician has prescribed to you. 

Special BAC Concentrations that Can Lead to a DUI Charge in Casa Grande

In some alcohol-related DUI situations, you do not need to have a BAC of 0.08 to be charged with DUI under Arizona law:

• If you are a commercial driver, you are presumed to be under the influence of alcohol with a BAC level as low as 0.04. 
• If you are under the age of 21, then any BAC level carries a presumption of impairment and will result in an underage DUI charge.

What Happens If I Decline to Give a BAC Sample?

By receiving an Arizona driver’s license, you automatically consent to submit to DUI breath, chemical, or blood tests during traffic stops. If you refuse to take a breathalyzer test at the station or processing facility (note that this is not the same as the portable breath testing device often administered on-scene, which you do not have to consent to), or refuse to submit to a blood test when stopped for an alleged DUI in Casa Grande, then you have violated your implied consent.

If this happens, then the Arizona Motor Vehicles Division (MVD) will suspend your driving privileges for one year. This license suspension is separate from any DUI sentence the court might impose if a court convicts you. 

Even if you are not convicted of a DUI, the Arizona MVD suspension of your driver’s license will remain in effect. 

What is an Intoxicating Drug?

In Arizona, many types of drugs, in addition to alcohol, can result in a DUI charge. Some of the better-known intoxicating substances under ARS 13-3401 include: 

• Amphetamines
• Methamphetamine
• Fentanyl
• Phencyclidine (PCP)
• Cannabis (Marijuana)
• Cocaine
• Opium
• Codeine
• Heroin
• Morphine
• Oxycodone
• Lysergic acid diethylamide (LSD)

You can also be charged with DUI for being under the influence of prescription-only medication if you don’t have a valid prescription or if the drug impairs your driving.

What Does “Actual Physical Control” of a Motor Vehicle Mean?

In Casa Grande, a police officer can arrest you for DUI even when your car is parked with the motor off. 

Arizona’s DUI laws do not define what actual “physical control” means, but Arizona courts have have identified examples: 

• Whether the vehicle’s engine was running or off
• Where the vehicle’s key was located
• If the vehicle’s engine was running for climate control only
• If the parking brake was on
• If the vehicle was in neutral or park
• If the vehicle’s headlights were on or off
• Where the car was parked
• The individual’s position inside the vehicle
• The individual’s reason for being inside the vehicle
• What the individual was doing in the car at the time the police arrived
• The time of day and weather conditions
• Whether the driver voluntarily pulled off the road

What Kinds of DUIs Does the Casa Grande Municipal Court Hear?

Under Arizona law, the following are misdemeanor-level DUI charges:

Types of DUI Charges Based on BAC Levels

DUI Type	Description
Standard DUI	Applies to a BAC of 0.01 to 0.149 or under the influence of an intoxicating substance
Extreme DUI	Applies to a BAC between 0.15 and 0.199
Super Extreme DUI	Applies if your BAC level is more than 0.199

If you are convicted of DUI in Casa Grande, the penalties for even a first-time conviction can be severe. You could face jail time, fines, license suspension, ignition interlock installation, community service, and probation.

The type of DUI conviction the court imposes on you will decide what penalties the prosecutor can seek against you.

• A standard DUI can result in a minimum of 10 days in jail (9 of which can be suspended upon successful completion of drug and/or alcohol treatment), more than $1,500 in fees and surcharges, a driver’s license suspension, and mandatory ignition interlock device installation.

This crime may be charged as a Class 4 or a Class 6 felony depending on the circumstances. You can also be sent to an Arizona prison for up to 3.75 years.

Common Arizona DUI Defenses

A strong defense by an experienced attorney can prevent a conviction or lower the penalties of DUI charges in Anthem. Possible defenses to a DUI charge that our DUI defense lawyers can employ on your behalf can include:

• You were not impaired
• You were not in actual physical control of the vehicle
• Unreliable or inaccurate drug or alcohol testing by the police
• The prosecution lacks enough evidence to convict you
• The prosecution has mishandled the evidence against you
• The police traffic stop or arrest was unlawful
• The police violated your constitutional rights
• You were not read your Miranda rights when subjected to questioning while in custody

What to Do (and Not Do) in a DUI Arrest

Understanding how to react during a DUI stop can be crucial in preventing or reducing the severity of a DUI charge against you.

Use the following tips to protect yourself as much as possible during a DUI arrest:

• Listen to your Miranda rights. The law enforcement officer should read you these rights after your arrest prior to questioning. They include the right to remain silent and the right to consult with an attorney.
• Stay calm and exercise your right to remain silent. Do not answer questions the officer asks about whether you have been drinking. Anything you say to police officers can be used against you.
• Do not agree to take field sobriety tests. While submitting is required, they cannot force you to participate, nor does refusing to participate in the field sobriety tests result in any violation of Arizona’s Implied Consent law (which again is what has implications to your driving privileges in Arizona.)
• Do not provide a breath sample in the Portable Breath Testing (PBT) device on the side of the road/while on scene. Submitting to this breath test is NOT required by Arizona’s Implied Consent law. Only failure to provide a breath sample into the Intoxilyzer machine back at the police station or DUI processing facility implicates Arizona’s Implied Consent law.
• If you are placed under arrest, do not resist. This could result in additional charges against you as well as serious physical injuries. You will have the chance to fight the charges later in a court of law.
• Contact an experienced Arizona nationally certified DUI defense attorney as soon as possible. If you are taken to the police station and/or jail, request that you be allowed to use your phone call and contact Rosenstein Law Group immediately at 480-248-7666.

An experienced criminal defense attorney, like the one you will receive from the Rosenstein Law Group, will take immediate steps to defend your legal rights in a DUI matter.
