What a DUI Attorney in San Diego Does for Your Case — Explained Step by Step So You Know Exactly What to Expect

TLDR: A DUI attorney in San Diego does far more than show up to court — from the moment of retention, Jason Ronis Law requests your DMV hearing within 10 days to protect your license, reviews every piece of evidence for suppression opportunities, challenges breathalyzer and blood test accuracy, negotiates for the best available outcome, and takes your case to trial if no acceptable resolution is offered. This post explains every step so you understand exactly what is happening with your case. Call Jason Ronis Law at (619) 859-2002 — free consultation 24/7, you speak directly with the attorney.

⚠️ THE MOST IMPORTANT THING A DUI ATTORNEY DOES HAPPENS IN THE FIRST 10 DAYS — NOT AT THE COURT DATE.

Step 1 — The 10-Day DMV Hearing Request: What Your DUI Attorney Does Before Your Court Date Even Exists

Most people assume that fighting a DUI starts at the first court date. It actually starts the day you are arrested — and the first deadline is one that most people without an attorney miss entirely.

When you are arrested for DUI in California, the arresting officer takes your physical driver’s license and gives you a pink temporary paper license. That paper license is valid for 30 days. After 30 days, your license is automatically suspended — unless you or your attorney requested a DMV Administrative Per Se hearing within 10 days of arrest.

This is a separate proceeding from criminal court. It is handled entirely by the California DMV, not the District Attorney or the courts. Winning the DMV hearing keeps your license. Losing it — or never requesting it — means suspension.

Jason Ronis Law requests the DMV APS hearing as the first action in every DUI case, on the day you call. The hearing also provides an early opportunity to cross-examine the arresting officer under oath, which sometimes produces evidence useful in the criminal case.

Step 2 — Reviewing the Evidence: What Your DUI Attorney Looks for That You Would Never See on Your Own

After the DMV hearing is filed, Jason Ronis Law immediately begins the evidence review process. This is where most of the real defense work happens — and where outcomes are won or lost long before any courtroom appearance.

The police report and body camera footage
Your attorney reads every word of the officer’s written report and reviews every second of available body camera and vehicle dashcam footage. Officers sometimes write reports that do not match what the camera shows. Inconsistencies become the foundation for suppression arguments and cross-examination.

The traffic stop documentation
Every DUI begins with a reason to stop you. That reason must be legally sufficient under the Fourth Amendment. A broken tail light, crossing a lane line, or making a wide turn can be the basis for a stop — but the officer’s characterization of what they observed must be accurate and legally sufficient. If it is not, a PC § 1538.5 motion to suppress can eliminate all evidence obtained from the stop — which typically means the entire DUI case is dismissed.

The breathalyzer calibration and maintenance records
Under California Code of Regulations Title 17, law enforcement agencies are required to maintain breathalyzer machines on a specific schedule, calibrate them with specific solutions, and document every test and maintenance procedure. Jason Ronis Law reviews these records for every DUI involving a breathalyzer. A machine that was not properly maintained, calibrated out of spec, or administered by an officer not trained to use it produces unreliable results — and those results are challengeable in court.

The blood test chain of custody
If your case involves a blood draw rather than a breathalyzer, Jason Ronis Law reviews the complete chain of custody from the draw through storage, transport, and laboratory testing. A break anywhere in this chain — a contaminated vial, an improperly stored sample, a missing transfer signature — can make the blood alcohol result inadmissible. Independent testing of the retained blood sample can be arranged if the chain of custody is intact but the result is disputed.

Step 3 — Filing Motions: What Your DUI Attorney Does to Challenge Evidence Before Trial

If the evidence review identifies legal problems with the stop, the breathalyzer, or the blood test, Jason Ronis Law files motions — formal legal requests asking the court to exclude that evidence.

PC § 1538.5 Motion to Suppress
This motion argues that the traffic stop, the search, or the DUI investigation was unlawful under the Fourth Amendment — and that all evidence obtained as a result should be excluded. A successful suppression motion typically results in the entire case being dismissed because without the suppressed evidence, the prosecution cannot meet its burden.

Motion to Challenge Breathalyzer Results
Based on Title 17 CCR record review, Jason Ronis Law can file motions arguing that the breathalyzer results are unreliable and should be excluded or given limited weight by the jury.

Rising BAC Defense
The legal limit is 0.08% while driving — not at the time of the blood draw or breathalyzer test, which typically happens 30 to 90 minutes after driving. Alcohol absorbs differently in different people. The rising BAC defense argues that your BAC was below 0.08% while you were actually driving, and crossed the threshold only after you stopped. This requires a specific type of expert testimony about absorption rates — and Jason Ronis Law works with qualified experts on this defense where the facts support it.

Step 4 — Plea Negotiation: What Your DUI Attorney Does When Dismissal Is Not Available

When the evidence does not support full dismissal, Jason Ronis Law negotiates with the prosecutor for the best available alternative outcome.

Wet Reckless — Vehicle Code § 23103.5
This is the most common and most valuable alternative to a DUI conviction. A wet reckless is a charge reduction to reckless driving with an alcohol notation — lower fines, shorter DUI school (typically 6 weeks instead of 3 months), no mandatory ignition interlock device in many cases, significantly lower insurance impact, and less damage to professional licenses and immigration status. It still counts as a prior offense for 10 years if you are arrested for DUI again — but its immediate consequences are dramatically less severe.

Dry Reckless — Vehicle Code § 23103
In cases where the evidence is particularly favorable to the defense, a reduction to dry reckless (no alcohol notation) is sometimes obtainable. This carries no DUI-related consequences at all — no DUI school requirement, no ignition interlock, no SR-22 requirement. These reductions are not offered frequently, but when the evidence supports it, Jason Ronis Law pursues them.

Minimum Sentence Negotiation
When a conviction is the only realistic outcome, Jason Ronis Law negotiates for the minimum available sentence — reducing fines, securing work-release or community service alternatives, and structuring DUI school enrollment to minimize disruption to your employment.

Step 5 — Trial: What Your DUI Attorney Does When No Acceptable Offer Is Made

If the prosecution’s offer does not reflect a fair resolution of your case, Jason Ronis Law prepares for and takes your case to jury trial.

A San Diego DUI trial before a jury requires: opening statements explaining the case theory, cross-examination of the arresting officer on every detail of the stop, field sobriety tests, and arrest procedures, presentation of expert witnesses on breathalyzer science or blood alcohol absorption, and closing arguments framing the evidence — and the reasonable doubt standard — in terms the jury can apply.

Going to trial is not the right choice in every case. But having an attorney who is genuinely prepared to try the case — and who the prosecution knows is prepared — produces better plea offers. Prosecutors offer better terms to defendants represented by attorneys who can and will go to trial.
