The decision of whether one should agree to a breath test, or deny and accept the penalties is very fact-based and depends on the individual circumstances of the case.
In most first infringement situations, it is wise to consent to a blood, breath, or urine check to work out your BAC following an arrest for DUI or DWI because refusal to consent results in one (1) year suspension of your driving privileges. Alternatively, a breath check that shows a .08% or higher results in only an automatic ninety (90) day suspension, and a restricted driver’s license is likely.
WARNING: If you are currently required to have an Interlock Device on your vehicle and you refuse to give a blood, breath, or urine sample to an officer, then you can be charged with a Felony Aggravated DUI, under A.R.S. §28-1383 Additionally, a refusal to submit to a chemical test now carries a municipal punishment of $500.00!
