Underage Drinking and Driving: Arizona’s Zero Tolerance Policy

Arizona has one of the toughest underage drinking and driving laws in the nation. The state enforces a strict zero-tolerance policy for drivers under the age of 21. That means any detectable amount of alcohol in an underage driver’s system—even a trace—can result in criminal charges and administrative penalties.

Under A.R.S. § 4-244(34), it is unlawful for a person under 21 years of age to drive or be in physical control of a motor vehicle while there is any alcohol in their body. Unlike adult drivers, who are typically considered impaired at a blood alcohol concentration (BAC) of 0.08% or more, underage drivers can be charged even with a BAC of 0.01%.

Consequences of Underage DUI in Arizona

A first-time underage DUI offense may include:
– License suspension for up to two years
– Mandatory alcohol education or treatment programs
– Community service or probation
– Jail time (up to 6 months in some cases)
– Criminal record, which can impact college applications, scholarships, and employment
If the BAC is above 0.08%, the underage driver can be charged with both standard DUI and underage DUI, facing the same penalties as an adult in addition to zero-tolerance sanctions.

In Arizona, the consequences of an underage DUI go beyond the courtroom. Insurance premiums can skyrocket, and having a criminal conviction at a young age can follow someone for years. Even a deferred or reduced sentence can still result in a record visible to employers, landlords, and schools.

Common Defenses to Underage DUI Charges

– Challenging the accuracy of the breathalyzer or BAC test
– Questioning whether the stop or arrest was lawful
– Arguing that the alcohol was not consumed or did not cause impairment
– Investigating whether the driver was actually in physical control of the vehicle
Early legal intervention is critical in underage DUI cases. An experienced attorney may be able to reduce or dismiss the charges, seek diversion programs, or negotiate for alternative sentencing that avoids long-term damage to the driver’s future.
