Everything you say can be used against you.
Evidence disappears. Witnesses’ memories fade. The prosecution starts building its case the moment of your arrest.
You also have just 15 days from your arrest to request an MVD hearing to contest your license suspension — a deadline most people miss entirely.
Mandatory jail time — minimum 10 consecutive days, even for first-time offenders
Automatic 90-day license suspension upon arrest, regardless of court outcome
Fines, fees, and total costs routinely exceeding $10,000
Mandatory ignition interlock device (IID) at your expense for 12–18 months
Permanent criminal record affecting employment, housing, and professional licensing
SR-22 high-risk insurance requirement for 3 years
Felony upgrade (aggravated DUI) if you have a prior, a child in the car, or drove on a suspended license
Challenging Breathalyzer & Blood Test Accuracy
Breathalyzers require proper calibration, maintenance logs, and certified operators. Blood tests must follow strict chain-of-custody protocols. A single failure in any of these procedures can render results inadmissible — and without a BAC reading, the state’s case often collapses entirely.
Unlawful Traffic Stop
Police must have reasonable suspicion to pull you over. If the stop was unlawful, all evidence gathered afterward — including BAC results, field sobriety tests, and officer observations — may be suppressed under the Fourth Amendment, leaving the prosecution with nothing to proceed on.
Rising BAC Defense
Alcohol continues absorbing into the bloodstream after your last drink. Your BAC at the time you were driving may have been below 0.08% even if it tested above that limit 30–60 minutes later. This is a scientifically supported defense we raise whenever the timeline supports it.
Field Sobriety Test Reliability
Field sobriety tests are highly subjective. Medical conditions, uneven road surfaces, footwear, weather, and individual officer bias all contribute to inaccurate results. We challenge the administration, scoring, and interpretation of every field test — not just whether you passed or failed.
Arizona’s Shelter Rule
Arizona law provides a defense if you pulled over and stopped driving to avoid being impaired behind the wheel. If you were using your vehicle as a shelter rather than exercising physical control of it, this is a recognized statutory defense that we evaluate in every applicable case.

“Put your trust in Mark”
“I was up against a Super Extreme DUI and looking at jail time. Mark and his staff worked diligently to provide me with the best possible defense — and I walked away with just a three-month license suspension. I would highly recommend this firm to anyone facing a DUI or in need of criminal defense.” — Jesse
“Case was ultimately dismissed”
“He handled my case ethically and professionally. My situation was unique but the bottom line is he represented me very well and my case was ultimately dismissed.” — Adam
“A name known by all”
“This is AZ’s best group of attorneys as far as I’m concerned. They handled my case with the utmost attention and never let me feel like the outcome was out of our control. Mr. Weingart is more than an institution in the local courts. If you want a strong ally with a name known by all, this is the guy.” — Christian Grey
