Breath Test Results in Virginia Are Sometimes Wrong

You can’t always rely on the results from a breath test to prove DUI.  There are too many factors that affect the readings given from breathalyzers in Virginia.  Prosecutors often use BAC readings as their main argument against a DUI defendant, but an experienced Virginia DUI attorney knows when these tests are inaccurate.

Breath testing equipment is frequently used when a police officer pulls over a suspect for DUI.  These devices are used to measure the blood alcohol content (BAC) of the driver, by utilizing a ratio to convert the alcohol in the breath to alcohol in the blood.  The first potential problem with breathalyzers is that it is automatically assumes that this ratio will be the same from person to person. 

If you have been arrested for DUI in Virginia and your BAC was above the legal limit, you need to have an expert review your case.  The various factors that can skew the results of breath tests are endless.  Radio frequency from a police officer’s radio or a nearby airport can affect your breath test results.  Mouth alcohol can throw off the reading, especially if you wear dentures.  Other chemicals are often mistaken for ethanol, which is found in alcoholic drinks.  Even certain medical conditions, such as diabetes can give false results from breathalyzers.

Don’t let your Virginia DUI conviction be based on the results from a breath test, without first looking into other possible causes that could have altered your BAC reading.  Talk with an experienced DUI attorney today by calling 888-DUI-ANSWER.
