What is chemical testing?

Chemical testing is very complex. Whether it’s breath testing, blood testing, both have their flaws. Breath tests are either fuel cell devices which means that they are a hand held device, or they’re an infrared device which means that they use light in determining an alcohol concentration. If you have not reached absorption, and you have not reached equilibrium that breath test can overstate the results by 200% to 300% Blood testing is equally complex, because it’s done through a process of chromatography. If you’ve been arrested for a DUI, and you have a question as to how to proceed from this point and you want to defend yourself, call me and we’ll examine your particular case and figure out what’s the best way to defend the case as we move forward.

How long does alcohol stay in your system?

People often ask, “how long does alcohol stay in your system?” It really depends on the factors of your situation, and it also depends on genetics. Not everybody absorbs alcohol at the same rate.

Determining a Driver’s Blood Alcohol Level

Blood alcohol testing is an attempt by law enforcement to determine how much alcohol is in a driver’s bloodstream. If a blood alcohol test result is 0.08% or higher, a driver is presumed to have violated the law (Vehicle Code 23152(b)). Keep in mind that the defense can present evidence, either through cross examination or affirmatively, that the test result is unreliable. It is important to remember that the blood alcohol test is supposed to determine the driver’s blood alcohol concentration at the time of driving the car, and not after the fact. There can be a significant difference between a driver’s blood alcohol concentration at the time of driving and the time the test is taken, which sometimes occurs an hour or more later.
