DUI defense: ways to challenge breathalyzer test results

When a Tennessee resident is stopped on suspicion of drunk driving they may be asked to submit to various tests to assess whether they are intoxicated. This legal blog has previously discussed field sobriety tests and the problems that may accompany their execution, but this post will focus on one of the main ways that law enforcement officials gain blood alcohol concentration information on their drunk driving suspects: breathalyzer tests.

A breathalyzer is a device that analyzes the concentration of alcohol in a person's system based on the contents of their breath. An individual must blow into the device for it to take a reading, then the system provides a reading of the person's BAC. Breathalyzer evidence can be used against individuals when they are charged with various drunk driving crimes.

However, breathalyzer results can be challenged in a number of ways. For example, breathalyzer machines must be calibrated to ensure that they are providing accurate readings of breath samples blown into them. Also, the officers who use them in the field to gain evidence against suspected drunk drivers must be certified to use them and trained on how to properly administer the tests. Records regarding breathalyzers must be maintained to ensure that they are properly serviced and working correctly.

A lot can go wrong when a law enforcement official asks a drunk driving suspect to blow into a breathalyzer. Drunk driving defense attorneys can help their clients assess their cases for problems in the collection of BAC evidence. To learn more about how breathalyzer evidence can be corrupted during alleged drunk driving cases, readers may wish to reach out to their DUI defense lawyers for more information.
