Ways Breathalyzer or Blood Tests May Be Used to Exonerate a DWI Suspect

Many people assume that if they fail a breathalyzer or blood test, it means they are guaranteed to be convicted of driving while intoxicated. However, this is untrue. Our skilled attorney can point out various factors that can lead to unreliable test results, including:

• Calibration was completed incorrectly - For a breathalyzer machine to work properly, it must first be appropriately calibrated. If the machine had been calibrated and maintained incorrectly, the results are likely unreliable. Our lawyer can highlight this issue and question the evidence against a client.
• A medical issue affected the test outcome - Medical conditions can impact whether someone passes or fails a breath or blood test. Diabetes or acid reflux have been shown to sometimes create falsely high blood alcohol concentration (BAC).
• Chain of custody issues - Blood test samples must be handled, stored, and tested properly. Any breaks in the chain of custody may render the results inadmissible.

Challenging the Results of Field Sobriety Tests

Field sobriety tests are used by law enforcement when someone is suspected of DWI. However, "failing" a field sobriety test does not necessarily mean that the person was, in fact, intoxicated. Factors unrelated to the person's sobriety can impact field sobriety test results. Some points to consider include:

• Weather can be a factor in field sobriety tests - Bad weather or poor road conditions can affect performance on these tests. A driver may struggle with balance for a variety of reasons, such as poor lighting.
• Health and age can impact field sobriety tests - If someone is suffering from a physical or cognitive ailment, they may be more likely to fail a sobriety test. For example, an older person may be more prone to balance issues. If law enforcement sees someone struggling with their balance, they may assume it is because they are intoxicated. In reality, the balance issue could stem from a health problem that the police officer is unaware of.
• Improper test administration may be to blame for a test failure - Officers need to administer field sobriety tests according to standardized procedures. Any deviation from these protocols can call the legitimacy of the officer's conclusions into question.

Using Witness Testimonies to Exonerate a Person Accused of DWI

As is the case in many criminal defense proceedings, witness testimonies can be a pivotal element of a case. People present during the arrest can lend credibility to your account of what happened. Potential witnesses could include:

• Passengers who were with you - If someone who was in the car with you had firsthand knowledge of whether you were intoxicated, it could be beneficial in disproving any DWI allegations or charges.
• Eyewitnesses to the incident - Bystanders who witnessed your driving behavior may be able to speak about whether you were driving erratically at the time leading up to a traffic stop.
• Video footage of the incident - Digital evidence can be a game-changer. Dashcam footage from law enforcement vehicles or videos taken by witnesses and bystanders may provide crucial context to the situation.
