Understanding Underage DUI Laws in Arizona

Arizona takes underage drinking and driving very seriously. The state has strict laws for drivers under 21 who get behind the wheel after consuming alcohol.
Arizona Legal Blood Alcohol Concentration Limits
For drivers under 21, any amount of alcohol in your system is illegal. This means even a 0.01% blood alcohol concentration (BAC) can lead to a DUI charge. For drivers 21 and over, the legal limit is 0.08% BAC.
Arizona also has higher penalties for "extreme" and "super extreme" DUIs:
- Extreme DUI: 0.15% BAC or higher
- Super Extreme DUI: 0.20% BAC or higher
These higher BAC levels come with harsher punishments, even for first-time offenders.
Arizona Zero Tolerance Policy
Arizona follows a "zero tolerance" policy for underage drinking and driving. This means if you're under 21 and have any detectable amount of alcohol in your system while driving, you can be charged with DUI.
This policy aims to prevent underage drinking and keep roads safe. Even if you don't feel impaired, any alcohol in your system can lead to arrest.
The zero tolerance law applies to:
- Driving any vehicle
- Being in "actual physical control" of a vehicle



Classifications of DUI Charges
Arizona classifies underage DUIs in a few ways:
- Baby DUI: Any measurable amount of alcohol for drivers under 21
- Standard DUI: BAC of 0.08% or higher (or any amount for under 21)
- Extreme DUI: BAC of 0.15% or higher
- Super Extreme DUI: BAC of 0.20% or higher
Each level comes with different penalties. Baby DUIs are often treated as misdemeanors, while higher BAC levels can lead to more serious charges.
Penalties and Consequences for Underage DUI

Getting a DUI under 21 in Arizona has serious penalties. You face license suspensions, required ignition interlock devices, and criminal charges.
Immediate and Long-Term License Suspensions
If you're under 21 and get a DUI in Arizona, your license will be suspended right away. For a first offense, you'll lose driving privileges for 90 days. A second offense means a 1-year suspension. During this time, you can't drive at all.
After the suspension ends, you'll need to pay fees to get your license back. You may also have to take classes or tests. These suspensions can make it hard to get to work or school.
Your insurance rates will likely go up too. Some companies may even drop your coverage. This can make it tough to drive legally for years after your DUI.
Mandatory Installation of Ignition Interlock Devices
After an underage DUI, you'll need to put an ignition interlock device in your car. This is a breathalyzer connected to your car's ignition. You have to blow into it to start the car.
The device stays in your car for at least 1 year. You pay for installation and monthly fees. This can cost hundreds of dollars.
If you try to start the car after drinking, it won't work. The device also does random tests while you're driving. Failed tests get reported to the court.
Criminal Charges and Classifications
An underage DUI is a class 1 misdemeanor in Arizona. This is the most serious type of misdemeanor. You could face up to 6 months in jail and $2,500 in fines.
You might also need to do community service or take alcohol classes. The exact penalties depend on your blood alcohol level and if it's your first offense.
A DUI stays on your record for years. This can make it harder to get jobs or rent apartments. Some schools may also reject your application if you have a DUI.
The Role of Legal Representation in Underage DUI Cases

Legal representation is crucial for those facing underage DUI charges. A skilled attorney can protect your rights and help navigate the complex legal system.
Importance of Hiring an Attorney
Getting a DUI lawyer in Arizona is vital when dealing with underage DUI charges. Attorneys know the ins and outs of DUI laws and can spot any errors in your case. They can challenge evidence, like breath test results or police procedures.
Your lawyer will explain your options and potential outcomes. They may be able to get charges reduced or even dropped. This can make a big difference in your future, especially for jobs and school.
Attorneys also help with court appearances and paperwork. This takes stress off you and your family during a tough time.
Seeking a Free Consultation
Many DUI lawyers offer free consultations. This is a chance to discuss your case without cost or commitment. You can ask questions and get advice on next steps.
During the consultation, bring any paperwork related to your case. This includes police reports and court documents. Be honest about what happened so the lawyer can give you the best advice.
Use this time to see if you feel comfortable with the attorney. Make sure they have experience with underage DUI cases in Arizona.
Defense Strategies Against Underage DUI Charges
A good lawyer will develop strong defense strategies for your case. They might question if the police had a valid reason to stop you. Your attorney could also challenge the accuracy of field sobriety or chemical tests.
In some cases, lawyers can argue for alternative sentencing. This might include alcohol education programs instead of harsh penalties. They can also try to keep the charge off your permanent record.
For cases involving minor in possession charges, your lawyer may seek to have these dealt with separately. This can sometimes result in lighter overall penalties.
