Driving under the influence (DUI) is a serious criminal offense in Arizona. The state has some of the strictest DUI laws in the country, and penalties for violating these laws can be severe. Here's an overview of the DUI law in Arizona.

The legal limit for blood alcohol concentration (BAC) in Arizona is 0.08%. This means that if you are caught driving with a BAC level of 0.08% or higher, you will be charged with a DUI offense. However, if you are under the age of 21, the legal limit is 0.00%, and if you are operating a commercial vehicle, the limit is 0.04%.

If you are convicted of a DUI offense in Arizona, you can face a range of penalties, including fines, jail time, and license suspension. The severity of the penalties will depend on the number of DUI offenses you have committed, your BAC level, and other factors.

For a first-time DUI offense, you can expect to face fines of up to $1,500, up to six months in jail, and a license suspension of 90 days. If your BAC level was 0.15% or higher, you may be required to install an ignition interlock device (IID) on your vehicle for up to 18 months.

For a second DUI offense within seven years of the first offense, you can expect fines of up to $3,000, up to six months in jail, and a license suspension of one year. You will also be required to install an IID on your vehicle for up to 18 months.

For a third DUI offense within seven years of the first offense, you can expect fines of up to $150,000, up to two years in prison, and a license revocation of three years. You will also be required to install an IID on your vehicle for up to two years.

In addition to these penalties, Arizona has an implied consent law, which means that if you refuse to take a chemical test when asked by a law enforcement officer, your license will be automatically suspended for one year.

If you are facing DUI charges in Arizona, it is important to speak with a qualified DUI defense attorney. An attorney can help you understand your legal options and develop a defense strategy that is tailored to your specific circumstances. With the help of an attorney, you may be able to avoid or minimize the penalties associated with a DUI conviction.

Overall, Arizona takes DUI offenses very seriously, and the penalties for violating the state's DUI laws can be severe. If you plan on drinking, it is best to designate a sober driver or use public transportation to avoid the risk of a DUI conviction.
