Understanding an Aggravated DUI Charge in Tucson

An aggravated DUI is a DUI charge elevated to a felony due to aggravating factors defined under ARS § 28-1383. These factors significantly increase the seriousness of the charge and its associated penalties.

Key Factors That Lead to an Aggravated DUI Charge in Tucson

  1. Driving with a Suspended or Revoked License: Operating a vehicle while under the influence with a suspended or revoked license.
  2. Repeat Offenses: Being charged with DUI after two or more DUI convictions within the past seven years.
  3. Child Passengers: Driving under the influence with a passenger under the age of 15 in the vehicle.
  4. Failure to Install an Ignition Interlock Device (IID): Non-compliance with a court-ordered IID installation can lead to felony charges.
  5. Accidents Causing Injury or Property Damage: Incidents resulting in serious injury or extensive property damage while driving under the influence.

Consequences of an Aggravated DUI Charge in Tucson

An aggravated DUI charge in Tucson comes with harsh penalties designed to deter repeat offenses. The consequences can include:

  • Imprisonment: First-time aggravated DUI offenses can result in prison sentences of up to 2.5 years.
  • License Revocation: A mandatory license revocation period of one year follows a conviction.
  • Fines and Fees: Expect thousands of dollars in fines, court costs, and other administrative fees.
  • Mandatory IID Installation: Convicted drivers must install an IID for up to two years after their license is reinstated.

These penalties emphasize the importance of having experienced legal representation like AZ DUI Pros to build a strong defense.


Hypothetical Scenarios

Scenario 1: Driving with a Suspended License

Jake, a Tucson resident, was previously convicted of a DUI, resulting in his driver’s license being suspended. Despite knowing his license was invalid, Jake decided to drive home after having a few beers at a party. On his way home, he was pulled over by an officer for speeding. During the stop, the officer noticed signs of impairment, such as the smell of alcohol and slurred speech. A breathalyzer test revealed Jake’s BAC was 0.12%, over Arizona’s legal limit of 0.08%.

Because Jake was driving with a suspended license, his offense escalated to an aggravated DUI charge in Tucson under ARS § 28-1383, a felony charge. Now, Jake faces harsh penalties, including potential prison time, a one-year license revocation, and significant fines. His case underscores the serious consequences of an aggravated DUI charge in Tucson and the importance of having legal representation to challenge the validity of the stop or identify procedural errors that could weaken the prosecution’s case.

Scenario 2: DUI with Child Passengers

Melissa, a single mother, was driving home with her 8-year-old son after attending a family gathering. During the event, Melissa consumed two glasses of wine but believed she was sober enough to drive. On her way home, she ran a red light and was pulled over. A breathalyzer revealed her BAC was 0.09%, slightly over the legal limit. The presence of her young son in the vehicle elevated the charge to an aggravated DUI charge in Tucson under ARS § 28-1383.

An aggravated DUI charge in Tucson involving a minor is a felony offense in Arizona, carrying severe penalties such as prison time, substantial fines, and mandatory installation of an ignition interlock device. Beyond these legal consequences, Melissa risks further scrutiny regarding her parenting and could even face custody challenges. A strong legal defense could focus on challenging the BAC results or presenting mitigating factors, such as her otherwise clean record, to negotiate reduced charges or alternative sentencing for her aggravated DUI charge in Tucson.

Defenses Against Aggravated DUI Charges in Tucson

An aggravated DUI charge in Tucson is a serious legal matter, but it doesn’t mean a conviction is guaranteed. With the right legal defense, it’s possible to reduce charges, minimize penalties, or even have the case dismissed. At AZ DUI Pros, our attorneys analyze every detail of your case to identify weaknesses in the prosecution’s evidence and build a strong defense.

Here are some of the most effective defenses against aggravated DUI charges:

1. Lack of Probable Cause for the Traffic Stop

Police officers must have a valid reason, known as probable cause, to stop your vehicle. Examples include speeding, erratic driving, or a visible traffic violation. If the stop was unjustified or based on mere suspicion, any evidence obtained afterward, such as breathalyzer results or field sobriety test findings, may be inadmissible in court.

2. Errors in Field Sobriety Tests

Field sobriety tests (FSTs) are often used to determine a driver’s level of impairment. However, these tests can be flawed for various reasons:

  • Poor lighting, uneven road surfaces, or inclement weather can affect performance.
  • Certain medical conditions, such as vertigo, injuries, or neurological disorders, can mimic signs of intoxication.

By questioning the validity of FST results, your attorney can weaken the prosecution’s case against you.

3. Inaccurate Breathalyzer Results

Breathalyzer devices must be properly maintained and calibrated to produce accurate BAC readings. Potential issues include:

  • Improper calibration or outdated equipment.
  • Operator error during the test.
  • The presence of medical conditions like acid reflux or diabetes, which can falsely elevate BAC readings.

If these factors are present, your attorney can challenge the reliability of the test results, possibly leading to the dismissal of your aggravated DUI charge in Tucson.

4. Procedural Errors by Law Enforcement

Strict procedures govern how officers handle DUI investigations. Examples of procedural errors include:

  • Failing to properly administer Miranda rights during an arrest.
  • Conducting unlawful searches without a warrant or probable cause.
  • Mishandling evidence, such as blood samples or breathalyzer records.

Any violation of your constitutional rights can provide grounds to suppress evidence, which can significantly weaken the prosecution’s case.

5. Alternative Explanations for BAC Levels

A high BAC reading does not always mean intoxication. Factors such as certain medications, residual mouth alcohol, or a recent diet change (e.g., a ketogenic diet) can elevate BAC levels without actual impairment. These factors can be presented as part of your defense to challenge the charge.


Relevant ARS Statutes

The main statute for aggravated DUI in Arizona is ARS § 28-1383, which outlines the aggravating factors and their corresponding penalties.

  • Subsection A: Lists conditions such as driving with a suspended license, multiple DUI offenses, or the presence of minors in the vehicle.
  • Subsection B: Specifies penalties, including mandatory prison time and fines for aggravated DUI convictions.
