A second-offense DUI in Arizona carries dramatically harsher penalties than a first — typical: mandatory 90 days (with 60 typically suspended), 1 year revocation. Lookback period: 7 years.

## Second-offense DUI penalties in Arizona
A second DUI conviction is in a different category from a first. Mandatory minimum jail goes up sharply, license suspension extends, ignition interlock becomes mandatory for longer periods, and the social and professional consequences multiply.
### Arizona 2nd-offense framework
- **Jail exposure:** Mandatory 90 days (with 60 typically suspended)
- **License consequence:** 1 year revocation
- **Lookback period:** 7 years (the window during which a prior counts as a "prior")
## Why the lookback matters
Lookback / washout periods determine whether your prior counts. Three patterns:
- **Short lookback (5-7 years)** — older priors don't enhance the new offense (FL, MS, NV, MI, NC, AZ, IN, ND, RI, WA, MS, MD)
- **Standard lookback (10 years)** — most states
- **Long lookback (15-20+ years)** — AK, IL, NE, DC
- **Lifetime lookback** — CO, MA, MO, NM, TX, VT, WI: ANY prior anywhere on your record counts forever
Out-of-state priors generally count if they would have qualified as a DUI in the new state.
## What gets harder at offense #2
**Mandatory minimum jail** — most states impose a multi-day or multi-week mandatory minimum that judges cannot suspend in full
**Longer license suspension** — typically 1-3 years (vs 90 days to 1 year on a 1st)
**Mandatory ignition interlock** — for the entire suspension period in many states; up to 2-3 years post-reinstatement
**Higher fines** — typically $500-$2,500 minimum (often $5,000+ when surcharges added)
**Mandatory alcohol/substance evaluation and treatment** — often residential or intensive outpatient
**Vehicle restrictions** — some states require vehicle forfeiture or special plates
**Higher probation costs and terms** — 2-5 years post-incarceration
**Felony elevation** — many states elevate a 2nd or 3rd offense to a felony (NY, OK, others within their lookback)
## Aggravators that compound 2nd-offense penalties
- **High BAC** (0.15 or 0.20+) — often doubles mandatory minimums
- **Child in vehicle** — separate child-endangerment charge in many states
- **Accident with injury** — felony in nearly every state
- **Refusal of breath test** — separate license consequences
- **Driving on suspended license** — additional charge
- **Open container / drug possession** — adds to the charge stack
## Diversion is rare
Most states limit DUI diversion to true first offenders. Pre-trial intervention, deferred adjudication, and ARD-style programs that work for first offenses generally don't apply to seconds.
## What you should do
Don't plead at first appearance. A 2nd-offense DUI case has technical defenses (calibration of the breath device, traffic-stop legality, blood-draw chain of custody, validity of the prior conviction, lookback computation) that a qualified Arizona DUI defense attorney can identify. Prior conviction CHALLENGES — collateral attacks on the validity of the prior — are often the most productive defense angle. Most Arizona criminal defense attorneys offer free initial consultations and accept payment plans.
