Deconstructing San Antonio DUI Charges With Forensic Precision
Deconstructing DUI charges with forensic precision.
An arrest is not a conviction. We analyze Intoxilyzer 9000 data, blood draw protocols, and NHTSA field sobriety test mechanics to expose the prosecution’s technical errors. Secure a methodical defense that protects your record and your driver’s license.
The Science of Your Defense
🔬 Breathalyzer Calibration Audits
The Intoxilyzer 9000 requires strict maintenance under Texas DPS regulations. We subpoena the machine’s calibration logs to identify maintenance failures that invalidate your BAC reading.
🩸 Blood Draw Protocol Scrutiny
Forensic blood analysis is highly susceptible to fermentation and improper storage. We review the chain of custody and gas chromatography data for contamination or procedural violations.
⚖️ NHTSA Field Test Deconstruction
Police routinely administer the Horizontal Gaze Nystagmus and Walk-and-Turn tests incorrectly. We analyze the body-cam footage frame-by-frame to prove the officer deviated from standardized training manuals.
🛑 Traffic Stop Legality
A traffic stop requires reasonable suspicion based on specific, articulable facts. If the SAPD officer lacked legal justification to pull you over, we file a motion to suppress all subsequent evidence.
📄 ALR Hearing Representation
You have exactly 15 days from your arrest to request an Administrative License Revocation hearing. We use this hearing to cross-examine the arresting officer under oath before the criminal trial begins.
Our Methodical Approach to DUI Defense
1
Secure the Evidence
We immediately file discovery requests for all SAPD body-cam footage, dash-cam video, and dispatch logs. We also initiate your ALR hearing request within the strict 15-day Texas deadline to protect your driving privileges.
2
Conduct Forensic Analysis
Rahman Davoodikhah and our legal team audit the breath or blood test data. We cross-reference the arresting officer’s actions against the current NHTSA DWI Detection manual to isolate procedural errors.
3
Execute the Defense Strategy
We present our technical findings to the Bexar County District Attorney to negotiate dismissals or reduced charges. If the state refuses to drop flawed evidence, we dismantle their case in front of a judge or jury.
15 Days

Frequently Asked Questions
Can you beat a DUI if I blew over a 0.08?
Yes. A breathalyzer printout is a piece of paper, not an absolute truth. We regularly invalidate Intoxilyzer 9000 results by proving the machine was improperly calibrated, the operator lacked current certification, or the 15-minute observation period was violated.
What happens to my license after a San Antonio DUI arrest?
The state will automatically suspend your driver’s license 40 days after your arrest unless you request an Administrative License Revocation (ALR) hearing within 15 days. We file this request immediately to keep you driving while we fight the criminal charges.
Should I have refused the field sobriety tests?
Field sobriety tests are voluntary in Texas, and refusing them deprives the prosecution of subjective evidence. If you did perform them, we will analyze the body-cam footage to show exactly how the officer failed to follow NHTSA administration protocols.
How does Rahman Davoodikhah approach a first-time DUI?
We treat a first offense with the same forensic scrutiny as a felony charge. We do not plead out cases just because it is a first offense; we analyze the probable cause for the stop and the science of the chemical test to force the prosecution to prove every element.
Challenge the Evidence Against You
The prosecution relies on the illusion of scientific certainty. Let us review your arrest details and identify the technical flaws in their case.
