Breath tests, taken by machines that are commonly known as “breathalyzer,” are used to determine how much alcohol is in a driver’s system. When drivers fail breath tests (meaning they are shown to have blood alcohol concentrations of 0.08% or higher), these individuals can be arrested for driving under the influence (DUI). It is important to note that while breathalyzers are commonly used, they are not 100% accurate. These devices do not directly measure the amount of alcohol in a person’s blood, but rather the amount of alcohol in the individual’s breath. Breath test devices use chemical reactions and scientific formulas in order to convert the amount of alcohol in a driver’s breath to a blood alcohol concentration (BAC) estimate.
With breath tests using indirect testing methods of BAC levels, this raises the question of how precise these tests really are. Furthermore, there are various factors that can end up altering a breath test reading, such as the driver’s physiology, the environment in which the test is taken, the way the test is administered, etc.
There are many grounds on which breathalyzer test results can be challenged. When you bring your case to our criminal defense law firm, Thomas Tears, Attorney at Law, our experienced Santa Ana criminal defense attorney can perform a thorough examination of the facts of your case, which can help him determine whether there were any factors that could have led to a false breath test reading. We can also look at information related to the specific breathalyzer device that was used to test you, such as whether the device was properly maintained or whether it had a history of technical problems.
Here are some of the common factors that could potentially affect the outcome of a breath test:
In 2009, the California Supreme Court entered a ruling that in some cases, defendants who are accused of drunk driving have grounds to challenge the validity of test results taken from their roadside breathalyzer tests, according to an Associated Press article in the San Jose Mercury News. Through this ruling, the Supreme Court acknowledged that breath test results can vary depending on the person. The article noted that studies have shown that breath-to-blood ratios can vary from person-to-person, especially when there are other factors weighing into the outcome.
