Boston DUI Defense Attorney

Breath and Chemical Tests

When one has been pulled over for suspicion of driving under the influence of drugs or alcohol, it is common to have a breathalyzer or chemical test administered to measure the blood alcohol concentration (BAC) in your blood.  These tests must be administered in a precise fashion or they will give false readings, and even then, there is a margin of error as with any scientific test.  In particular, the breathalyzer test is subject to error, as the correct procedure in administering the test is frequently violated.  If you have been arrested and charged with a DUI offense and had a breathalyzer test administered to you, it is crucial that you get legal representation from an aggressive Boston DUI Defense Attorney to assist you in fighting your charges.  We can also help explain how we can work in challenging the breath test, as well as working to expose common blood test flaws.

There are so many potential errors in breathalyzer and other chemical tests that it is shocking that the results are even allowed in court.  For example, it is well known that the breathalyzer test registers 15% higher than the actual BAC level in approximately 23% of the people tested.  That means that if one is arrested for having a BAC level of .08% or higher, there is a strong possibility that you are totally innocent of the charge.

Not only is the test known to be fairly inaccurate in measuring BAC levels, there are other factors that affect the readings on these devices.  For example, they deteriorate over time and become more and more inaccurate.  They need frequent calibration and maintenance, and if this is not done per the proper schedule, the likelihood of an incorrect reading is increased again.  If an accident occurred and you are tested with the breathalyzer afterwards, blood in the mouth can also create incorrect readings, as well as breath spray and other compounds that may come from medicines you have consumed — not alcohol.  If you have been arrested and charged with a DUI in Boston, it is vital to get legal help from a Boston DUI Defense Attorney as soon after the arrest as possible.  The legal team will aggressively fight for your defense and will stand by you throughout the process.
