Breathalyzer Test Jacksonville FL

A Breathalyzer Test is a device used to measure the blood alcohol content of a person's breath, particularly in cases where a police officer suspects that the person is driving under the influence (DUI) or driving while intoxicated (DWI).

While the courts and law enforcement officials use breathalyzers frequently in drinking and driving cases, the scary truth is that unless proper rules and procedures are followed carefully, the results can be unfairly skewed.

A Breathalyzer Test detects alcohol on a person's breath by using a chemical reaction that measures small amounts of alcohol droplets suspended in a person's breath. The Breathalyzer Test itself contains several chemicals, each a different color, which change color when they come into contact with alcohol.

Most jurisdictions require that police officers obtain two breath samples from a DUI suspect within a short period of time. If the two samples show a large discrepancy between results, it is a good indication that either the machine is not working properly or the results were contaminated in some way.

Unfortunately, while the breathalyzer continues to be a frequently used Field Sobriety Test to determine if someone has been drinking and driving, the test contains many flaws. For example, it has been proven that if someone who has been pulled over for a potential DUI is running a fever, that person likely will show a higher reading on the breathalyzer than someone who is otherwise healthy. Additional factors that can contribute to an inaccurate breathalyzer read include temperature variances, measurement of other substances in the area including gasoline, inaccurate calibration of the machine, and substances found naturally in the breath of diabetics or those on a diet.

Because of the inherent flaws in breathalyzer accuracy, it tends to be one of the number one defenses of DUI attorneys in DUI cases. Believe it or not, there have been instances where a person that consumed no alcohol registered a high blood alcohol content (BAC) on a breathalyzer while others who are clearly intoxicated registered no BAC. Therefore, those arrested for a DUI may have an effective defense in challenging the results of a breathalyzer test if they have an experienced and informed DUI defense attorney like Casey Bryant to defend them.
