What Drivers Need to Know

Tempe, Arizona, is known for its vibrant nightlife, Arizona State University campus, and busy roadways. With such a high concentration of bars, restaurants, and college students, DUI enforcement in Tempe is aggressive. Police frequently conduct traffic stops and DUI checkpoints, especially on weekends and near the downtown entertainment district. If you’re arrested for DUI in Tempe, the penalties can be severe, and having an experienced defense attorney is crucial.

At Rideout Law Group, we defend clients charged with DUI across Tempe and Maricopa County, bringing the insight of former prosecutors and trial-tested attorneys to your case.

Arizona DUI Laws: The Basics

Under Arizona Revised Statutes §28-1381, it’s illegal to drive or be in physical control of a vehicle while:

  • Impaired to the slightest degree by alcohol or drugs
  • Having a Blood Alcohol Concentration (BAC) of 0.08% or higher
  • Operating a commercial vehicle with a BAC of 0.04% or higher
  • Being under 21 with any amount of alcohol in your system

Arizona’s zero-tolerance policy means even minor impairment can lead to charges. In Tempe, this often impacts ASU students and young professionals.

Types of DUI Charges in Tempe

  • Standard DUI: BAC between 0.08%–0.149%
  • Extreme DUI: BAC between 0.15%–0.199%
  • Super Extreme DUI: BAC of 0.20% or higher
  • Aggravated DUI: A felony offense, triggered by multiple prior DUIs, driving with a suspended license, or transporting a child under 15 while impaired

DUI Penalties in Tempe

Penalties for DUI in Tempe are harsh and mandatory under Arizona law:

  • First Offense DUI: At least 10 days in jail (with 9 possibly suspended), fines of $1,500+, license suspension, ignition interlock device
  • Extreme DUI: 30 days in jail, steeper fines, extended interlock requirement
  • Aggravated DUI: Felony charges, prison time, license revocation, vehicle forfeiture

A conviction can also impact employment, scholarships for ASU students, and professional licensing.

Where DUI Cases Are Heard in Tempe

If you are charged with DUI in Tempe, your case will likely go through:

  • Tempe Municipal Court (for misdemeanors)
  • Maricopa County Superior Court (for felonies and aggravated DUI)

Familiarity with these courts, prosecutors, and judges is essential when building a strong defense.

DUI Defense Strategies

While DUI charges are serious, they can be fought. Common defense strategies include:

  • Challenging the legality of the traffic stop
  • Questioning the accuracy of breath or blood tests
  • Reviewing whether police followed proper procedure
  • Arguing that you were not in “actual physical control” of the vehicle
