DUI vs DWI Drunk Driving Laws in Phoenix, Arizona

Understanding DUI vs. DWI in Arizona

Arizona law makes no distinction between “DWI” and “DUI.” While many states use “DWI” to refer specifically to alcohol-based offenses and “DUI” for broader impairment cases, Arizona Revised Statutes (A.R.S. § 28-1381) uses only “DUI” to encompass all impaired driving—whether due to alcohol, illegal drugs, prescription medication, or any intoxicating substance.

Arizona BAC Limits & DUI Categories

Standard DUI: BAC ≥ 0.08% or any observable impairment.
Commercial DUI: BAC ≥ 0.04%.
Under-21 Zero Tolerance: Any detectable alcohol.
Extreme DUI: BAC ≥ 0.15%.
Super Extreme DUI: BAC ≥ 0.20%.

Arizona’s DUI laws are among the strictest in the nation—penalties scale up significantly with BAC level, repeat offenses, or aggravating circumstances.

First-Offense DUI Penalties in Phoenix

Even a first conviction brings severe consequences:

Jail: Minimum 10 consecutive days (possible suspension of 9 days with alcohol education completion).
Fines: Starting at $1,250 plus surcharges.
License Suspension: 90 days to 1 year.
Ignition Interlock Device (IID): Required for at least 12 months.

Extreme & Super Extreme DUI Penalties

Extreme DUI (≥ 0.15% BAC):
- Jail: 30 consecutive days.
- Fine: $2,500 minimum.
Super Extreme DUI (≥ 0.20% BAC):
- Jail: Up to 45 days.
- Fine: $3,200 minimum.

Both require IID installation, alcohol counseling, and possible community service.

Enforcement in Phoenix

Phoenix Police and Arizona DPS employ DUI checkpoints, roving patrols, and specialized DUI task forces—often targeting holiday weekends and known high-risk corridors. Officers use field sobriety tests, portable breathalyzers, and chemical testing, but under Arizona law, you can still be charged below 0.08% BAC if “impaired to the slightest degree.”

Refusal & Administrative License Suspension

Under Arizona’s implied consent law, refusing a BAC or chemical test results in automatic license suspension—12 months for a first refusal, up to 2 years for a second. Refusal also does not shield you from prosecution; officers may rely on other evidence to pursue DUI charges.

Defense Strategies from Arizona Justice Law Group

As a trial-tested DUI attorney, Zalman Sapad often builds defenses by:

Challenging the legality of the traffic stop.
Examining equipment calibration and maintenance.
Investigating officer training and procedural compliance.
Identifying medical or environmental factors affecting test results.
Filing motions to suppress unlawfully obtained evidence.

His approach blends rigorous factual investigation with legal precision, often resulting in reduced charges or outright dismissals.

Out-of-State Implications

Arizona participates in the Interstate Driver’s License Compact, meaning DUI convictions often follow you to your home state. Even non-Arizona residents may face IID installation and suspension requirements before reinstatement.
