Driving Under the Influence (DUI) laws in Arizona are among the strictest in the United States. The state has implemented rigorous measures to deter impaired driving, protect public safety, and reduce the incidence of alcohol and drug-related traffic incidents. This article provides a comprehensive overview of Arizona's DUI laws, including legal definitions, penalties, enforcement practices, and resources for individuals facing DUI charges.
Legal Definitions
Driving Under the Influence (DUI)
In Arizona, a person is considered to be driving under the influence if they operate a vehicle while impaired by alcohol, drugs, or any combination thereof. The legal framework for DUI is outlined in Arizona Revised Statutes (A.R.S.) § 28-1381. According to this statute, a person can be charged with DUI if:
- They have a blood alcohol concentration (BAC) of 0.08% or higher within two hours of driving.
- They are impaired to the slightest degree by alcohol or drugs.
- They have any amount of a drug defined in A.R.S. § 13-3401 or its metabolite in their body.
Extreme DUI
Arizona law also defines "Extreme DUI" under A.R.S. § 28-1382. This applies when a person has a BAC of 0.15% or higher within two hours of driving. The penalties for Extreme DUI are more severe than those for standard DUI offenses.
Aggravated DUI
Aggravated DUI, as defined in A.R.S. § 28-1383, involves more serious circumstances, such as:
- Committing a DUI while driving on a suspended, revoked, or canceled license.
- Having two prior DUI convictions within the past seven years.
- Committing a DUI with a passenger under the age of 15 in the vehicle.
- Refusing to submit to a BAC test while having an ignition interlock device (IID) installed.
Penalties for DUI Offenses
First Offense DUI
For a first-time DUI offense, the penalties can include:
- A minimum of 10 days in jail, with the possibility of 9 days being suspended if the offender completes an alcohol education program.
- Fines and assessments totaling approximately $1,500.
- A 90-day license suspension.
- Installation of an IID for 12 months.
- Completion of a drug and alcohol screening, education, or treatment program.
Second Offense DUI
A second DUI offense within seven years carries harsher penalties:
- A minimum of 90 days in jail, with 60 days potentially suspended upon completion of an alcohol education program.
- Fines and assessments totaling approximately $3,500.
- A one-year license revocation.
- Installation of an IID for 12 months.
- Completion of a drug and alcohol screening, education, or treatment program.
Extreme DUI Penalties
For a first-time Extreme DUI offense, the penalties include:
- A minimum of 30 days in jail, with the possibility of 21 days being suspended if the offender completes an alcohol education program.
- Fines and assessments totaling approximately $2,500.
- A 90-day license suspension.
- Installation of an IID for 12 months.
- Completion of a drug and alcohol screening, education, or treatment program.
Aggravated DUI Penalties
Aggravated DUI offenses result in even more severe consequences:
- A minimum of 4 months in prison.
- Fines and assessments totaling approximately $4,000.
- A three-year license revocation.
- Installation of an IID for 24 months.
- Completion of a drug and alcohol screening, education, or treatment program.
Enforcement Practices
Sobriety Checkpoints
Arizona law enforcement agencies frequently conduct sobriety checkpoints to deter and identify impaired drivers. These checkpoints are legal under both state and federal law, provided they meet certain criteria, such as being publicly announced in advance and conducted in a non-discriminatory manner.
Field Sobriety Tests
When a driver is suspected of DUI, officers may administer field sobriety tests (FSTs) to assess impairment. Common FSTs include the Horizontal Gaze Nystagmus (HGN) test, the Walk-and-Turn test, and the One-Leg Stand test. These tests are designed to evaluate a driver's physical and cognitive abilities.
Chemical Tests
Arizona's Implied Consent Law (A.R.S. § 28-1321) requires drivers to submit to chemical tests (breath, blood, or urine) if suspected of DUI. Refusal to take a chemical test can result in an automatic license suspension and other penalties.
Legal Defenses
Challenging the Traffic Stop
One common defense in DUI cases is challenging the legality of the traffic stop. If the stop was conducted without reasonable suspicion or probable cause, any evidence obtained during the stop may be inadmissible in court.
Questioning the Accuracy of Chemical Tests
Another defense strategy involves questioning the accuracy of chemical tests. Factors such as improper calibration of breathalyzer devices, contamination of blood samples, or improper administration of tests can be used to challenge the validity of the results.
Medical Conditions
Certain medical conditions, such as acid reflux or diabetes, can affect BAC readings. Defense attorneys may present medical evidence to explain elevated BAC levels that are not due to alcohol consumption.
Resources for Individuals Facing DUI Charges
Legal Assistance
Individuals facing DUI charges in Arizona are strongly advised to seek legal representation. Experienced DUI attorneys can provide guidance, develop defense strategies, and represent clients in court. The Arizona State Bar Association offers a lawyer referral service to help individuals find qualified attorneys.
Alcohol Education Programs
Completion of an alcohol education or treatment program is often a requirement for DUI offenders. The Arizona Department of Health Services provides a list of approved programs on their website: Arizona Department of Health Services.
Ignition Interlock Device (IID) Providers
Offenders required to install an IID can find a list of approved providers on the Arizona Department of Transportation's website: Arizona Department of Transportation.
Conclusion
Arizona's DUI laws are designed to promote road safety and deter impaired driving. The state imposes strict penalties on offenders, including jail time, fines, license suspensions, and mandatory installation of ignition interlock devices. Understanding the legal definitions, penalties, enforcement practices, and available resources is crucial for individuals facing DUI charges. By adhering to these laws and seeking appropriate legal assistance, individuals can navigate the complexities of DUI cases and work towards a resolution.
