Taking a breathalyzer while being investigated for a DUI is no fun. This graphic dispels some common myths about DUI breathalyzers. The safest way to avoid a DUI is not to drive a vehicle. The Munoz Law Office defends those accused of DUI and challenges the accuracy and reliability of breathalyzers. DUI enforcement in Arizona is serious and Prosecuting agencies in Phoenix, Tempe, Scottsdale, Chandler, and Mesa have zero tolerance. If you have been arrested and want to challenge the results of a breath or blood test call our office for a consultation.
