Why You Should Consider Challenging Breath or Blood Tests in Charleston
Challenging chemical test evidence can lead to important benefits, such as reducing the accuracy or admissibility of results, which in turn can reduce criminal exposure or affect plea negotiations. In Charleston DUI matters, mistakes in test administration, broken equipment, or improper lab handling are not uncommon and can be decisive when highlighted properly. A careful review may uncover grounds to challenge a test or to seek mitigation before administrative panels. Considering these options early helps preserve defenses and often achieves better overall outcomes for clients.
Another reason to pursue challenges is the potential to protect driving privileges, which are frequently at stake after a DUI arrest. Administrative hearings in Mississippi operate under separate timelines and standards, and a successful challenge to test procedures can prevent suspension of a license. For people in Charleston who rely on driving for work and family duties, avoiding or minimizing license loss can be as important as resolving criminal charges. Strategic, timely action increases the chance of favorable administrative and court results.
Typical Situations That Lead to Breath and Blood Test Challenges
Several recurring circumstances often trigger the need to challenge breath or blood test results: missing or inconsistent device maintenance records, gaps in chain-of-custody documentation, improper handling of samples, questionable timing between driving and testing, or procedural deviations by officers or lab staff. In Charleston cases, these issues can significantly affect the reliability of chemical evidence. Identifying which of these circumstances apply to a specific situation helps determine the most effective defensive approach for resolving the matter in court or at administrative hearings.
Missing or Incomplete Calibration Records
When breath testing devices lack complete calibration or maintenance records, it is reasonable to question the reliability of readings. Calibration ensures the device measures alcohol levels accurately, and missing certificates or irregular maintenance schedules can be raised to challenge results. In Charleston DUI matters, obtaining device logs and service records is a routine step in evaluating whether breath test readings should be admitted or given full weight. Identifying these gaps early allows the defense to press for exclusion or reduced reliance on the device’s readings.
Chain of Custody Breaks for Blood Samples
Blood test reliability depends on a clear chain of custody showing who handled the sample and when. Breaks, missing signatures, or unexplained storage gaps can undermine confidence in test results. In Charleston and across Mississippi, defense teams request all custody logs and lab transfer documents to verify proper handling. If records show unexplained transfers or potential contamination risks, those facts can form strong arguments to challenge the validity of blood test evidence at hearings and trial.
Delays or Irregularities in Testing Procedures
Delays between the time of driving and the administration of tests, or procedural irregularities during sample collection, can affect the interpretation of results. For example, extended time before testing may allow alcohol levels to change, and improper sample labeling could risk contamination. In Charleston cases, documenting timing, officer actions, and testing environment helps determine whether test results accurately reflect impairment at the time of driving. Identifying these issues supports arguments to limit or exclude questionable evidence.
