Some Common DUI Legal Defenses That May Help You

Some Common DUI Legal Defenses That May Help YouFacing a DUI charge in West Chester, Chester County, or Delaware County, Pennsylvania, can be a daunting experience. The implications of such charges can significantly affect your life, from potential jail time to hefty fines and the loss of driving privileges. It can even be more disastrous if you are someone who drives commercial vehicles for work. However, with the support of a skilled West Chester criminal defense lawyer, there are several legal defenses that may help mitigate the consequences or even result in a dismissal of charges. Here, we explore some common DUI defenses that experienced attorneys often employ in such cases.

1. Inaccurate Sobriety Testing

Field sobriety tests are not always reliable indicators of intoxication. Factors such as physical impairments, nervousness, or even the conditions in which the tests were conducted can lead to false positives.

  • Common Issues: Improper administration, subjective interpretation, and external factors affecting performance.

2. Faulty Breathalyzer Results

Breathalyzer devices must be calibrated and maintained regularly to ensure accurate readings. Your attorney can challenge the results if there’s evidence that the device was faulty or the procedure was incorrectly administered.

  • Key Points to Consider: Calibration records, operator training, and the timing of the test.

3. Illegal Traffic Stop

Law enforcement must have a valid reason, known as probable cause, to initiate a traffic stop. If the stop was made without probable cause, any evidence obtained during the stop, including DUI tests, may be deemed inadmissible in court.

  • Defense Strategy: Reviewing dashcam footage, officer testimony, and the circumstances leading to the stop.

4. Rising Blood Alcohol Concentration

The body continues to absorb alcohol for some time after drinking, which means your Blood Alcohol Concentration (BAC) could have been lower while driving than when tested. This “rising BAC” defense can challenge the assumption that you were over the legal limit while operating the vehicle.

  • Considerations: Time elapsed between driving and testing, and consumption pattern.

5. Medical Conditions

Certain medical conditions can mimic the symptoms of intoxication or even interfere with breathalyzer results. Conditions such as GERD, diabetes, or even a low-carb diet can produce false positives.

  • Supporting Evidence: Medical records, expert testimony, and related research.
