Whether this is your first time being pulled over for potential drinking and driving or you have been down this road before, you probably know you will be asked to take a breathalyzer test. For decades, this test has been one of the tools that law enforcement and the prosecution use against DWI suspects when charging them with a crime. While they rely heavily on them for the evidence they provide, the question remains: are they always accurate?
The answer is no, not always. This is why it is imperative that you have an experienced Woodbury drunk driving accident lawyer on your side when you are facing DWI charges.
Why are Breathalyzers Used?
In all states, drivers who have a blood alcohol content (BAC) level of 0.08 percent or more can be charged with a DWI as they are presumed to be legally intoxicated. Law enforcement must have ways to prove what your BAC was at the time you were stopped. The most accurate is a blood test, but these require taking the subject to a clinic or a hospital. A breathalyzer is ideal for use in the field as they are portable and easy to administer. They also provide immediate results.
Breathalyzer tests can be used for a law enforcement officer to establish probable cause, but the results might not always be admissible in court. The problem with breathalyzer tests is that they are not always reliable. Your Woodbury drunk driving accident lawyer will work to determine if your results were possibly skewed and challenge their admissibility.
Factors that Make a Breathalyzer Test Inaccurate
Breathalyzer results are not always reliable. The accuracy of a breathalyzer test depends upon many factors. The administrator of the test must be skilled and careful. Your Woodbury drunk driving accident attorney may be able to use these factors as a part of your defense. Potential factors that can cause unreliable results include:
- The presence of specific foreign substances such as mouthwashes, toothache medicines, and breath fresheners which all can contain alcohol
- Calibration which must be done regularly
- How new the batteries are in the device
- Software wh can occasionally experience a bug or a glitch just like computer software
- User error—although breathalyzers are user-friendly, they still demand attention to detail
- Inconsistency—to be accurate, breathalyzers need to be performed on the same subject several times as they rely on fuel cell sensor technology
- The environment such as the presence of chemicals in plastics or adhesives or the presence of paint fumes or varnish
