Are Breath or Blood Tests for DUI Accurate?

The accuracy of breath tests has been called into question recently in many DUI cases. Although it is the most common form of testing to see if someone is driving under the influence, many experts agree they are not as effective as blood tests in determining someone's blood alcohol concentration and if they are indeed driving over the legal limit. A DUI attorney will look to see how intoxication was determined when defending a DUI case, including if the breath test was administered as it should have been and also call into question just how accurate these tests actually are, whether administered correctly or not.

Experts agree that if a breath test is the only evidence that a person was intoxicated, then it may not be valid enough evidence.  The results of these tests can be off due to individual physiological reasons.  There have been cases where the result of a breath test has been off by up to 15% from the results a blood test.  The accuracy of actual blood tests can also often be brought into question as well.

If you are facing a DUI charge and you question the BAC test results, contact a Fresno, Madera, Kings or Tulare county DUI lawyer today.
