Many drivers in Arizona will have been pulled over at some point for one reason or another, or investigated following their involvement in an accident. If this has happened to you, you will already be aware that this can involve an investigation into whether you were under the influence of alcohol at the time of the incident. If your blood alcohol concentration is found to be at or above the legal limit of 0.08 percent, you could find yourself faced with drunk driving charges.

However, something not everyone realizes is that you could still be charged even if your BAC is below the limit. Arizona is one of a number of states that use zero-tolerance or no-tolerance laws. This means that you could end up being arrested for having a much lower BAC than would get you into trouble in another state.

There are many factors that come into play during a DUI arrest, such as previous convictions and the severity of the alleged offense, often determined by the damage caused and your BAC measurement. Other matters such as whether there were minors in your vehicle at the time of the incident can also have an effect on the consequences of the investigation.

Being faced with drunk driving charges is a daunting matter and you may wonder what you can do or where you can turn. Fortunately, an attorney may be able to provide the advice and support you need. He or she can evaluate the circumstances of your arrest and may be able to help you build your defense.
