Breath or Blood Alchohol Testing:

The most common evidence in DUI cases are the breath alcohol test results. Several DUI breath test machines are used by the various Southern California counties. Mr. Tripathi can challenge the reliability of any of these alcohol breath testing devices.

A blood test is often considered to be the most accurate type of chemical test that can be performed. If this evidence is presented, many times a retest of the blood can be very persuasive.

Calculating BAC - Blood alcohol content, or BAC, is the detectable amount of alcohol in a person's blood stream. It is measured in milligrams percent. A driver in California, who is over the age of 21, is over the legal limit if the BAC is 0.08% or higher. A driver with a BAC lower than 0.08% may still be considered under the influence if they show signs of intoxication .
