When it comes to DUI arrests, the breathalyzer test is a tool that law enforcement commonly uses to determine a driver’s level of intoxication. At The Law Firm of Frederick J. Brynn, P.C., we understand the critical role these tests play in DUI cases. Our experienced MD DUI attorney has dealt with numerous cases where breathalyzer results were a focal point of the legal proceedings.

Understanding Breathalyzer Tests

A breathalyzer is a device that measures the Blood Alcohol Content (BAC) in a person’s breath. When a driver is suspected of DUI, law enforcement officers may use a breathalyzer test to ascertain if the driver’s BAC is over the legal limit, which in most states, including Maryland, is 0.08%.

The Science Behind Breathalyzer Tests

The breathalyzer works on the principle that alcohol in the bloodstream is transferred to the lungs. The device measures the amount of alcohol in the breath, which is then converted to an estimated BAC level. This reading plays a crucial role in DUI arrests, as it provides a quantifiable measure of intoxication.

The Legal Implications Of Breathalyzer Results

In DUI cases, the result of a breathalyzer test can significantly influence the legal process. A BAC reading over the legal limit often serves as a primary piece of evidence in prosecuting DUI offenses. However, it’s important to note that breathalyzer tests are not infallible and can be subject to errors and challenges.

Challenging Breathalyzer Test Results

There are several grounds on which the accuracy of a breathalyzer test can be contested:

  • Device Calibration and Maintenance: If the breathalyzer was not properly calibrated or maintained, its accuracy could be compromised.
  • Administration of the Test: The way the test was administered can also affect the results. Law enforcement officers must follow specific protocols when conducting a breathalyzer test.
  • Medical Conditions and External Factors: Certain medical conditions and external factors, such as diet or the use of mouthwash, can impact breathalyzer readings.

How Hiring A Lawyer Can Help

Our skilled MD DUI attorney can scrutinize the circumstances surrounding a breathalyzer test to identify any potential issues or irregularities. By challenging the validity of the test results, an attorney can potentially weaken the prosecution’s case against the defendant.
