What Is the Legal Alcohol Limit in Arizona?

In Arizona, you may be unclear about the different permissible blood alcohol levels, how they are calculated, and their meaning. If you live in a zero-tolerance state like Arizona, knowing how to calculate your blood alcohol content (BAC) might save you from hefty charges.

For drivers in Arizona, a BAC of 0.08% or greater is a driving under the influence (DUI) offense, regardless of how sober or unimpaired they may feel. The legal limit for drivers of commercial vehicles is far lower, set at less than 0.04%. We further explain in-depth the legal blood alcohol levels in Phoenix, AZ.

What Is Blood Alcohol Concentration (BAC)?

Blood alcohol content (BAC) is the gold standard for medical and legal applications in the United States. A BAC of 1.0% indicates that there is one gram of alcohol in every 100 milliliters of your blood. The factors that affect a person’s BAC include:

• Alcoholic beverages consumed
• Amount of  alcoholic beverage consumed
• Your body weight
• Your biological sex
• Drugs or medications consumed during or before drinking
• Amount of food consumed

Blood alcohol concentration (BAC) is the alcohol percentage in the driver’s blood. It’s the way law enforcement assesses the intoxication level.

Testing Blood Alcohol Levels in Phoenix

Arizona law enforcement uses two methods to determine blood alcohol concentration levels: a breath test and a blood test.

A breathalyzer is a quick and easy method to test a driver’s BAC. It is used by police officers in Phoenix and throughout Arizona to detect drunk drivers. Mobile breathalyzers have a high margin of error and are not accepted in legal proceedings. Blood samples are highly accurate for BAC testing. They are more labor intensive and require laboratory testing.

Whether the drunk driver receives criminal charges and gets convicted, you can still hold them liable for your damages and pursue compensation in a civil court. Our Phoenix car accident lawyers can use either of these blood alcohol tests as evidence for the drunk driver’s liability. If you’re in southern Arizona and need representation, a DUI accident lawyer in Tucson from our team can help protect your rights and secure compensation.

What Are Arizona’s Legal BAC Limits?

The 0.08% level is Arizona’s threshold for charging DUI cases. But the state also has “Extreme DUI” and “Super Extreme DUI,” which are more severe forms of driving under the influence.

Last but not least, there is an issue with drunk driving by minors in Phoenix and other areas of Arizona. Underage drivers with any amount of blood alcohol concentration (BAC) in their systems are not allowed to operate a motor vehicle in Arizona.

The official legal blood alcohol content in Arizona is:

• Standard DUI: 0.08% to 0.149%
• Extreme DUI: 0.15% to 0.199%
• Super Extreme DUI: 0.20% or higher
• Underage DUI: 0.01% or higher

Types of DUI Charges by BAC Level in Arizona

Depending on your blood alcohol concentration (BAC) level and other circumstances, you might be charged with one of three categories of DUI in Arizona.

Standard DUI

In Arizona, you may face up to 10 days in jail and a $1,500 fine for a first-time DUI offense. You might also be subject to screening and counseling, paying jail fees, and an $80 monitoring fee.

The driver’s license is revoked for 90 days, and offenders must use an ignition interlock device for a year. An additional 90 days in jail is the penalty for a second conviction of ordinary DUI in Arizona with a BAC between 0.08% and 0.15%.

After six days, you may apply for home detention. A $3,500 fine, plus the expenses of jail time or home detention, and an $80 monitoring charge are also imposed. A 12-month need to use an ignition interlock device and a 90-day license suspension are the penalties for DWI offenders.

Extreme DUI

If this is your first violation, you might face up to 30 days in jail with the possibility of home detention. You must pay $2,780 in penalties, jail/home detention fees, and a monitoring cost of $80. Going through a screening process is mandatory, then comes participation in therapy.

Along with these penalties are a 12-month mandatory use of the ignition interlock device and a 90-day license suspension. The consequences for a second Extreme DUI conviction are more severe, including a minimum jail term of 120 days. The offender must additionally pay a monitoring charge of $3,740 per month in addition to the expense of jail time.

Super Extreme DUI

In Arizona, a Super Extreme DUI is defined as a BAC reading of 0.20% or higher with a minimum jail term of 45 days. The total amount of penalties and costs you must pay amounts to around $3,240.

Your license will be revoked for 90 days, and you’ll have to use an ignition interlock device for another 18 months.

Can You Get a DUI Below 0.08% in Arizona?

Although most people know that 0.08% BAC is the limit, it’s important to remember that a police officer may still make an arrest even if your BAC is below the legal limit. However, it may be inferred that you weren’t under the influence of alcohol if your BAC is 0.05% or under.

There is no room for error in driving under the influence for minors. Minors should not have any BAC level, period. Even if the minor’s BAC is below the state’s legal limit, they will still be prosecuted for driving under the influence if found drinking and driving.

BAC Limits for Commercial and Rideshare Drivers

Commercial drivers are subject to stricter limits on their blood alcohol content. Their major reason is the nature of their jobs and the number of hours they spend behind the wheel. A commercial driver’s blood alcohol concentration (BAC) limit is just 0.04%, which is half the limit for regular drivers. If you were injured by an impaired Uber or Lyft driver, a Phoenix rideshare accident lawyer can help determine which insurance policies and liability rules may apply.
