Common DUI Defenses Attorney In San Diego, California
Questioning the Accuracy of Breath and Blood Tests
Breathalyzers and blood tests are commonly regarded as hard evidence in DUI cases, yet it's important to acknowledge that they are not always entirely reliable. For these machines to provide accurate results, they must be properly calibrated and meticulously maintained, and law enforcement officers are required to adhere to strict protocols during the administration of these tests.
Even minor errors in calibration or procedural adherence can significantly skew the results. Moreover, individual health issues, the presence of residual mouth alcohol, or the precise timing of when the test is administered can all contribute to falsely elevated blood alcohol content readings.
In this context, David Simon takes a comprehensive look at the entire testing process. He evaluates crucial elements such as the thorough documentation of the testing procedure, the accuracy of calibration records, and the methodology used for collecting the samples. If any flaws or irregularities are identified in how the tests are conducted or handled, there may be grounds to effectively challenge the results. This scrutiny could potentially lead to the results being deemed inadmissible as evidence in court, thereby impacting the outcome of the DUI case significantly.

Challenging the Stop and Field Sobriety Tests
One of the most common DUI defenses involves questioning whether the initial traffic stop was legal. If law enforcement didn’t have reasonable suspicion to pull you over, any evidence gathered afterward — including test results — may be thrown out. Additionally, field sobriety tests are subjective and can be affected by things like fatigue, nervousness, poor lighting, uneven ground, or a medical condition.
David Simon examines the full timeline of the stop and arrest, including dashcam footage, officer reports, and witness accounts, to determine whether your rights were violated or the tests were administered improperly.
Addressing Police Misconduct or Procedural Errors
In some DUI cases, a strong defense comes down to how the arrest was handled. If your rights were violated — whether through an unlawful search, denial of legal counsel, or use of excessive force — those actions can directly impact the case. Additionally, missing paperwork, delayed lab reports, or inconsistencies in the officer’s version of events may raise doubt about the prosecution's case.
David Simon takes a close look at every detail surrounding your arrest to identify any errors or misconduct that may support a motion to suppress evidence or reduce charges. In DUI defense, no detail is too small when your freedom and record are on the line.
