Investigative Article: The Truth About Preliminary Breath Tests vs. Breathalyzer Tests
Picture this: you're driving down the road and suddenly, the red and blue lights of a police car appear in your rearview mirror. You pull over to the side of the road and the officer approaches your window. After asking you a few routine questions, the officer asks you to take a preliminary breath test (PBT) to check your blood alcohol concentration (BAC). What should you do? Is this test accurate, and can you refuse to take it?
What is a Preliminary Breath Test (PBT)?
A PBT is a small, handheld breath-testing device used by law enforcement officers to estimate a person's BAC during a traffic stop. This test is often conducted on the side of the road and is considered a "preliminary" test because it is not admissible as evidence in court.
How Accurate is a PBT?
There are a number of factors that can influence the accuracy of a PBT, including the type of device used, the calibration of the device, the technique used by the officer, and the presence of certain physical conditions or substances that may interfere with the results. Despite these potential issues, many law enforcement agencies continue to rely on PBTs as a way to quickly and easily estimate a person's BAC during a traffic stop.
Can You Refuse a PBT?
In most states, including Arizona, drivers can refuse to take a PBT without facing legal consequences. However, it's important to note that refusing a PBT may result in additional penalties, such as the suspension of your driver's license. Additionally, while a PBT cannot be used as evidence in court, it can provide probable cause for an officer to make an arrest and require a more accurate BAC test, such as a Breathalyzer test.
What is a Breathalyzer Test?
A Breathalyzer test is a more accurate and reliable method of testing a person's BAC. This test is typically conducted at a police station or other location using a larger, more sophisticated device. Unlike a PBT, the results of a Breathalyzer test are admissible as evidence in court and can play a key role in a DUI case.
Why is the Accuracy of BAC Tests Important?
The accuracy of BAC tests is crucial in DUI cases, as these results can have serious legal and personal consequences. Depending on the state and the circumstances of the offense, a DUI conviction may result in fines, loss of driving privileges, mandatory alcohol education or treatment, and even jail time. Additionally, a DUI conviction can have long-lasting effects on a person's personal and professional life, including damage to their reputation, difficulty finding employment, and increased insurance rates.
The Importance of a Skilled Defense Attorney
If you've been arrested for DUI, it's important to consult with a skilled defense attorney who can help protect your rights and ensure the accuracy of any BAC tests that were administered. An experienced DUI lawyer can review the circumstances of your arrest, challenge the validity of any tests or evidence obtained, and work to negotiate a favorable outcome in your case.
Conclusion
While a PBT may provide a quick estimate of a person's BAC during a traffic stop, this test is not always accurate and can be influenced by a number of factors. Drivers can legally refuse a PBT, but doing so may result in additional penalties and consequences. For more accurate and reliable results, a Breathalyzer test is typically used, and the accuracy of these tests is crucial in DUI cases. If you've been arrested for DUI, it's important to consult with a skilled defense attorney who can help protect your rights and ensure a fair outcome in your case.
