Toughest State DUI Laws: A Look at Arizona's Stringent Penalties

Driving under the influence of alcohol or drugs is a serious offense that can lead to significant legal consequences. Each state in the United States implements its own DUI laws, which can vary widely in terms of fines, jail time, and other penalties.

Overview of Arizona's DUI Laws

Arizona is known for its strict DUI laws and tough penalties for offenders. In fact, Arizona has some of the most rigorous DUI laws in the country for first-time offenders. One of the notable aspects of Arizona's DUI laws is the mandatory use of an Ignition Interlock Device (IID) for all DUI convictions, including those involving first-time offenders. This policy is often reserved for repeat offenders in other states or is part of alternative sentencing options. In addition, Arizona has harsher penalties for DUIs with a blood alcohol concentration (BAC) of 0.15 or higher, as well as for drivers who transport minors while under the influence.

Arizona's Tough DUI Penalties

Arizona's DUI penalties are among the toughest in the country. The state has established mandatory minimum penalties for DUI convictions, which can include fines, jail time, community service, and driver's license suspension. The penalties increase for repeat offenders, and aggravated DUIs, which involve certain aggravating factors such as driving with a suspended license or causing an accident, can result in even harsher penalties.


Arizona imposes mandatory fines for DUI convictions, which can range from $250 to $2,500 for first-time offenders. For aggravated DUIs, fines can range from $3,000 to $150,000, depending on the circumstances. In addition to fines, offenders may be required to pay for court costs, mandatory alcohol screening, and counseling.

Jail Time

Arizona has mandatory jail sentences for DUI convictions. For first-time offenders, the minimum sentence is ten consecutive days. The maximum sentence is six months. For repeat offenders, mandatory minimum sentences are longer. For example, a second DUI conviction within seven years requires a minimum of 90 days in jail, and a third conviction requires a minimum of four months in jail. Aggravated DUIs can result in even longer mandatory minimum jail sentences, ranging from one year to 15 years depending on the degree of aggravation.

Driver's License Suspension

Arizona suspends driver's licenses for DUI convictions, even for first-time offenders. The length of the suspension varies depending on the circumstances of the offense. For a first-time DUI conviction, the suspension is 90 days. For a second conviction within seven years, the suspension is one year. A third conviction within seven years results in a three-year suspension. In addition, Arizona requires drivers with a suspended license to install an IID at their own expense.

Ignition Interlock Device

As previously mentioned, Arizona requires the use of an IID for all DUI convictions, including first-time offenders. An IID is a device that is installed in a vehicle that measures a driver's BAC before allowing the vehicle to start. If the driver's BAC is above a certain level, the vehicle will not start. The driver is also required to perform random tests while driving to ensure that they do not consume alcohol while behind the wheel. The cost of installing and maintaining an IID can be significant, and offenders are required to pay for it themselves.

Aggravated DUI

Aggravated DUIs are DUI convictions that involve certain aggravating factors, such as driving with a suspended license, causing an accident, having a minor passenger in the vehicle, or having a BAC above a certain level. In Arizona, aggravated DUIs carry harsher penalties than regular DUIs. Offenders can face longer mandatory jail sentences, higher fines, and longer driver's license suspensions. In addition, aggravated DUIs are considered felony offenses, which can result in long-lasting consequences.


Arizona's DUI laws are some of the most stringent in the country, with mandatory minimum penalties for all DUI convictions and the requirement of an IID for all offenders. The state takes driving under the influence seriously and is committed to deterring individuals from making the dangerous decision to drink and drive.
