Questioning the Validity of Field Sobriety Tests
Field sobriety tests are commonly used by law enforcement to determine if a driver is impaired. These tests often include walking in a straight line, standing on one leg, or following an object with your eyes. While these tests may seem straightforward, they are not always accurate. Factors like poor weather conditions, uneven surfaces, or even a driver’s medical condition can affect performance on these tests. Challenging the results of field sobriety tests involves questioning whether the officer properly administered the tests and whether the driver’s performance was influenced by factors unrelated to alcohol or drug use. If the results of these tests are unreliable, they may not be strong enough to support a DUI charge.Examining Breathalyzer Test Results
Breathalyzer devices are commonly used to measure a person’s blood alcohol concentration. However, these devices are not foolproof and can produce inaccurate readings. For a breathalyzer test to be reliable, the device must be properly maintained, calibrated, and used correctly. Errors can occur if the officer administering the test lacks proper training or if the device has not been serviced as required. Additionally, factors such as medical conditions or even certain foods can produce false positives. By examining the accuracy of the breathalyzer test and the circumstances surrounding its use, it may be possible to challenge the validity of this evidence in court.
Reviewing Blood Test Procedures
Blood tests are often considered more reliable than breathalyzer tests, but they are not without flaws. For blood test results to hold up in court, strict procedures must be followed during collection, handling, and testing. If the sample is not properly stored or is contaminated, it can lead to inaccurate results. Chain of custody is also critical, as any gaps in documentation can call the reliability of the sample into question. Reviewing how the blood sample was collected and tested can uncover errors that may weaken the prosecution’s case.Challenging the Traffic Stop
In many DUI cases, the evidence begins with the traffic stop itself. For a stop to be lawful, the officer must have a valid reason to pull the driver over, such as observing a traffic violation or having reasonable suspicion of impairment. If the stop was not justified, any evidence gathered afterward, including field sobriety tests or breathalyzer results, may be inadmissible in court. By reviewing the circumstances of the traffic stop, a defense attorney can determine whether the officer acted within the law. If the stop was unlawful, it could significantly impact the outcome of the case.
Garth Best was extremely helpful in my case. He explored and explained everything to me clearly and never stopped checking out every option. I am absolutely grateful I chose him as my attorney. Best and Brock are a great choice for representation. Thanks again.

Matt Brock did an outstanding job with my case. Very thorough and knowledgeable attorney, highly recommended. Its very obvious through my interactions with him that he has the experience and knowledge to win in court. I will not go anywhere else. Great job, much appreciated.

Addressing Officer Misconduct or Errors
Law enforcement officers must follow specific procedures when handling DUI cases. Any failure to follow these procedures could compromise the evidence against you. For example, an officer may fail to properly read Miranda rights, mishandle evidence, or make incorrect assumptions during the investigation. Such errors can create opportunities to challenge the prosecution’s case. Highlighting these mistakes can show that the evidence may not be as strong as the state claims, which could lead to a more favorable outcome for the defendant.Evaluating Witness Statements and Dashcam Footage
In some DUI cases, witness statements or dashcam footage can play a significant role. Witnesses may include passengers, other drivers, or bystanders who observed the traffic stop or arrest. Dashcam footage can provide an unbiased account of the events, potentially revealing inconsistencies in the officer’s version of what occurred. Reviewing this evidence can help identify discrepancies that may cast doubt on the case against you. If the prosecution’s evidence does not match the facts, it could weaken their ability to prove the charges beyond a reasonable doubt.Using Medical or Scientific Evidence
Medical or scientific evidence can be a powerful tool in challenging DUI allegations. Certain medical conditions, such as acid reflux or diabetes, can mimic the signs of impairment or affect the results of a breathalyzer test. Similarly, fatigue, stress, or anxiety can impact a driver’s ability to perform well on field sobriety tests. By presenting evidence of these factors, a defense attorney can argue that the observed signs of impairment were unrelated to alcohol or drug use. Scientific evidence can provide an alternative explanation for the prosecution’s claims, creating doubt in the minds of the judge or jury.Related Videos
