Mesa DUI Defense Attorneys

Put Former Prosecutors on Your Side

If you or someone you know has been arrested for driving under the influence of alcohol or drugs, you need to contact a Mesa DUI defense attorney immediately. Our award-winning defense attorneys are dedicated to helping clients fight their charges and protect their rights. As our team includes a former police officer and former prosecutors, Knowles Law Firm, PLC understands the other side of DUI cases and knows how to attack the evidence against you.

DUI Charges & Penalties in Arizona

Driving under the influence of alcohol or drugs is a serious offense in Arizona. There are serious penalties for even a first time arrest with a blood alcohol concentration (BAC) of .08% or more. If a defendant's BAC is high, .15 to .199%, then they would be charged with an extreme DUI and face more severe penalties. A super extreme DUI would be the charge in cases where a driver has a BAC of .20% or higher.

If you are arrested and convicted of a first-time DUI, you could face:

  • A mandatory minimum sentence of 10 days in jail up (and a minimum 45 days for a super extreme DUI)
  • Fines of up to $1,480 to $3,250
  • License suspension for a minimum of 90 days
  • Mandatory ignition interlock device (IID) installation for 1 year

A second DUI conviction in Arizona could mean:

  • Minimum 90 days in jail (up to a minimum of 180 days for a super extreme DUI)
  • $3,000 to $4,250 in fines
  • License suspension for a minimum of 1 year
  • Mandatory IID for 1 year

A third DUI conviction would mean felony charges and:

  • At least 4 months in jail
  • 1 year of license suspension
  • Two years with an IID
  • More than $4,000 in fines

Even if you are never convicted of DUI, if you refuse to take a blood breath test when asked to by law enforcement, then you could still be looking at having your driver's license suspended for a minimum of one year. Whatever type of drugged or drunk driving charges you face, you need a legal advocate on your side whom you can depend on.
