Is the Breathalyzer Test Always Right?

Breathalyzer tests have greatly increased in popularity as they are more objective than field sobriety tests as well as portable and easy to use. However, even though Breathalyzer tests may be more accurate than field sobriety tests, this does not mean that they are infallible. In fact, there are several issues that can lead to erroneous Breathalyzer results, including:

• Old chemicals used to detect alcohol in the sample
• The same assumed blood-to-breath ratio for all individuals
• Incorrect calibration of the electrical sensor

Despite these potential problems, you can still be charged with drunk driving based on the results of a Breathalyzer test. If you believe that these results are wrong, please contact a knowledgeable San Antonio DWI test defense lawyer from the Law Offices of Chris S. Barnett at 210-587-6464 today.
