Yes, in Arizona, you can still be charged with a DUI if your BAC (blood alcohol concentration) was below the legal limit of 0.08%. If there is evidence that you were impaired while driving, such as erratic driving or failed field sobriety tests, you can still face charges for a DUI even if your BAC was below the legal limit. A skilled DUI lawyer can help defend against these charges and challenge any evidence presented by the prosecution.
