Underage First Offense DUI

Underage DUI laws in Arizona are particularly strict due to the state’s “zero tolerance” policy. Here are the key aspects of a first offense underage DUI (under the age of 21) in Arizona:

  • Zero Tolerance Law: In Arizona, it’s illegal for anyone under the age of 21 to operate a vehicle with any detectable amount of alcohol in their system. This is stricter than the standard DUI laws for drivers over the age of 21, where the BAC limit is 0.08%.
  • Penalties: The penalties for a first offense underage DUI can include:
    • License Suspension: A two-year suspension of the driver’s license is typical for underage DUI offenders.
    • Fines: Though there might not be a jail sentence for a first offense underage DUI, fines and mandatory fees can be imposed.
    • Alcohol Education and Counseling: Mandatory participation in alcohol education programs or counseling sessions.
    • Community Service: Courts often impose community service requirements.
  • Long-term Impacts:
    • Criminal Record: An underage DUI can result in a misdemeanor conviction, impacting future job prospects, educational opportunities, and more.
    • Insurance Rates: As with any DUI conviction, insurance rates will likely increase significantly.
  • Ignition Interlock Device (IID): Though not always mandatory for first-time underage offenders, a judge might order the installation of an IID based on the circumstances of the case.
  • Legal Proceedings: Underage DUI charges can also lead to other legal consequences, including additional charges if other minors were in the vehicle, or if there was damage or injury caused while driving under the influence.

Arizona’s approach to underage DUI is aimed at discouraging underage drinking and driving through severe penalties and extensive loss of driving privileges, emphasizing the state’s commitment to road safety.

CDL First Offense DUI Penalties

For holders of a Commercial Driver’s License (CDL) in Arizona, the penalties for a first offense DUI are even more stringent than those for non-commercial drivers, given the higher standards of safety expected from professional drivers. Here’s an overview of the key penalties and consequences:

  • Legal BAC Limit: The legal blood alcohol concentration (BAC) limit for CDL holders while operating a commercial vehicle is 0.04%, which is half the limit set for standard drivers.
  • License Suspension:
    • Commercial License: A first DUI offense results in a minimum one-year disqualification of the CDL.
    • Non-commercial Driving: If the CDL holder was operating a non-commercial vehicle at the time of the DUI, their standard driving license can also be suspended for the same durations as non-CDL holders (usually 90 days).
  • Jail Time and Fines: The jail time and fines are similar to those for non-commercial DUI offenders:
    • Jail Time: Minimum of 10 consecutive days.
    • Fines: Minimum of $250, with additional assessments that can total over $1,500.
  • Ignition Interlock Device (IID): Installation of an IID on any vehicle operated by the offender, including personal vehicles, is required for at least one year.
  • Employment Impact: A DUI conviction can severely impact a CDL holder’s current and future employment opportunities in commercial driving. Many employers in the transportation sector have zero-tolerance policies for DUI offenses.
  • Insurance: CDL holders can expect significant increases in insurance premiums or may even be dropped by their insurance providers.
  • Alcohol Education and Treatment: Mandatory participation in alcohol education or treatment programs is often required.
  • Permanent Record: A DUI conviction will appear on the CDL driver’s permanent driving record, potentially affecting job prospects and other opportunities.

The penalties underscore the higher expectations and responsibilities placed on professional drivers, and the serious consequences of impaired driving when holding a CDL in Arizona.

Ignition Interlock Requirements First Offense DUI


In Arizona, the ignition interlock device (IID) requirements for a first offense DUI are mandatory and part of the state’s effort to reduce repeat offenses by individuals convicted of DUI. Here’s how the IID requirements typically work for a first DUI offense:

  • Duration: For a standard first offense DUI, an IID must be installed on every vehicle operated by the offender for at least one year. The duration can increase depending on the specifics of the offense:
    • Extreme DUI (BAC of 0.15% to less than 0.20%): The IID is required for at least one year.
    • Super Extreme DUI (BAC of 0.20% or higher): The requirement extends to 18 months.
  • Installation: The IID must be installed by an authorized service provider. The offender is responsible for all costs associated with the IID, including installation, monthly rental fees, and maintenance.
  • Operation: The IID requires the driver to provide a breath sample before the vehicle can start. If the device detects alcohol above a pre-set limit (usually very low, close to zero), the vehicle will not start.
  • Monitoring: Regular monitoring and data download sessions are required to ensure compliance. These check-ins also incur a fee, which the offender must pay.
  • Compliance: Failure to comply with the IID requirements, such as tampering with the device, missing monitoring appointments, or driving a vehicle without an installed IID, can result in extended IID periods, additional fines, or further legal penalties.
  • Removal: After the mandated period, the IID can be removed by a certified installer once the Arizona Motor Vehicle Department (MVD) confirms that the offender has met all the requirements and has no outstanding violations.

These requirements are designed to allow offenders to continue driving under close supervision, reinforcing safe driving habits and ensuring public safety on the roads.

Implied Consent Law

Arizona’s implied consent law is a critical component of its DUI enforcement framework. This law stipulates that by operating a motor vehicle within the state, drivers automatically consent to chemical testing (blood, breath, or urine) to determine alcohol concentration or the presence of drugs if they are arrested on suspicion of DUI. Here’s how it specifically applies to a first offense DUI:

  • Testing Requirement: After a lawful arrest for suspected DUI, the driver is required to submit to and complete a chemical test as directed by a law enforcement officer.
  • Choice of Test: Law enforcement typically chooses the type of test (blood, breath, or urine). In some cases, the driver may have the option to choose, but this is at the discretion of the officer.
  • Consequences of Refusal:
    • License Suspension: Refusal to submit to a chemical test results in an automatic suspension of the driver’s license for 12 months for a first refusal. This is an administrative action taken by the Arizona Department of Transportation regardless of the outcome of any DUI charges.
    • Evidence in Court: The fact that a driver refused to take a chemical test can also be used as evidence against them in a DUI court proceeding, potentially leading to harsher penalties.
  • Right to Additional Testing: Drivers have the right to obtain additional independent testing at their own expense after undergoing the test requested by law enforcement.
  • Warrant for Testing: If a driver refuses the test and the officer still wishes to conduct it, they may seek a warrant from a judge to compel the test. Compliance is mandatory once a warrant is issued.

The implied consent law is designed to facilitate the enforcement of DUI laws by ensuring that officers can obtain the necessary evidence to prosecute DUI offenses effectively. It underscores the serious legal obligations drivers have to comply with testing if suspected of DUI in Arizona.

DUI Class Requirements

In Arizona, DUI classes, also known as alcohol education or treatment programs, are a standard requirement for individuals convicted of a first-time DUI. These programs are part of the penalties designed to educate offenders about the risks associated with DUI and to prevent future offenses. Here’s what typically involves:

  • Screening: Before enrolling in any classes, DUI offenders are usually required to undergo a screening process to assess their alcohol consumption patterns and determine the appropriate level of education or treatment needed. The screening can help in tailoring the intervention to the individual’s needs.
  • Education Programs: For a first-time DUI offender, the education program often consists of at least 16 hours of classroom instruction. These classes cover a range of topics including the effects of alcohol and drugs on the body and driving ability, Arizona DUI laws, and the social and financial consequences of DUI.
  • Treatment Programs: Depending on the results of the initial screening, some offenders may also be required to participate in further treatment programs. This could include counseling sessions, support group meetings, or more extensive substance abuse treatment programs.
  • Costs: Offenders are responsible for the costs associated with these programs, which can vary based on the provider and the specific requirements of the treatment plan.
  • Completion: Successful completion of the required education or treatment program is often a condition for reinstating driving privileges or for the completion of probation terms. Non-compliance can result in extended suspensions or additional penalties.

Driver License Hearing


In Arizona, if you are arrested for a DUI, you’ll face not only criminal charges but also administrative actions by the Arizona Department of Transportation (ADOT), specifically through the Motor Vehicle Division (MVD). The administrative aspect primarily involves a hearing concerning your driving privileges. Here’s how the DMV (or MVD, in Arizona) hearing process generally works for a first offense DUI:

  • Requesting the Hearing: When you are arrested for a DUI, your driver’s license is typically seized, and you are issued a temporary license that lasts 15 days. You have the right to request an MVD hearing to challenge the suspension of your license. This request must be made within 15 days of the arrest. If you do not request a hearing within this period, your license suspension will automatically begin on the 16th day post-arrest.
  • Purpose of the Hearing: The MVD hearing is an administrative procedure, separate from the criminal case, focusing solely on your driving privileges. The hearing will determine whether your license should be suspended due to failing or refusing a chemical test under Arizona’s implied consent law. The hearing does not address whether you are guilty of a DUI.
  • Issues Reviewed: The hearing officer will review specific issues, such as:
    • Whether the officer had reasonable grounds to believe you were driving or in actual physical control of a vehicle while under the influence.
    • Whether you were arrested.
    • Whether you refused to submit to or failed to complete the blood, breath, or urine tests after being requested to do so by an officer.
    • If you refused the test, did the officer properly advise you of the consequences of refusal?
  • Conducting the Hearing: The hearing is usually conducted over the phone, but you can request an in-person hearing. You can represent yourself, or you can have an attorney represent you. During the hearing, both you (or your attorney) and the officer who made the DUI arrest can present evidence and argue the case.
  • Outcome: If the MVD hearing officer finds that the suspension is justified, your license will be suspended for a period depending on whether it was a test failure or refusal:
    • Test Failure: Suspension typically lasts for 90 days.
    • Test Refusal: Suspension for a first refusal is typically 12 months.
  • Appeal: If you disagree with the outcome of the MVD hearing, you can usually appeal the decision to a higher court, but this must be done within a specific timeframe.

It’s important to note that the MVD hearing and the criminal DUI proceedings are separate. Even if you win the MVD hearing, you can still be prosecuted and convicted in criminal court, which may include additional penalties like fines, jail time, mandatory DUI education courses, and the installation of an ignition interlock device.

Final Thoughts

Beyond legal penalties, a DUI conviction can have extensive personal and professional consequences. It can affect your employment, especially if your job requires driving. Insurance premiums will likely increase significantly. There might also be social and family impacts stemming from a DUI conviction.

The DUI arrest triggers both criminal and administrative processes. The administrative process involves dealing with the Motor Vehicle Division for license suspension issues, separate from any criminal court proceedings. You have rights during DUI proceedings, including the right to legal representation. Given the complexities of DUI laws and the consequences of a conviction, consulting with an attorney who specializes in DUI cases can be crucial. An attorney can help navigate the legal challenges, potentially minimize penalties, or even contest the charges.
