Los Angeles DUI and Toxicology

Los Angeles DUI Attorney

Blood sampleAll driving under the influence cases require that the prosecutor prove beyond a reasonable doubt that the defendant was under the influence of alcohol or drugs at the time that he or she was driving a motor vehicle. To prove intoxication, law enforcement and prosecutors rely on the officer’s observations as well as the toxicology reports generated showing the results of chemical testing. In California, a driver can choose either a breath or blood test when he or she is arrested on suspicion of DUI. Drivers who refuse testing can still be charged with driving under the influence in violation of California Vehicle Code Section 23152(a) VC in addition to the refusal allegation which would add additional penalties, including mandatory jail time.

Toxicology is the study of the effects of foreign chemicals on the human body and many scientists focus on this area of study. There may be several factors that affect a driver’s BAC level at the time of testing and in some cases it may be necessary to procure the services of a toxicologist to serve as an expert witness for the defense. Toxicologists can be useful in challenging both breath and blood test results.

It is important to remember that the results of chemical testing only show what a person’s BAC was at the time of testing and not necessarily what his or her BAC was at the time of driving. Toxicologists study how alcohol and drugs are absorbed and metabolized by the human body. When a person drinks alcohol, his or her BAC will slowly rise as the alcohol is being absorbed into the body, level off and then fall as the alcohol is processed and excreted. There may be cases where a person in the rising blood alcohol phase of absorption has a BAC below the 0.08 percent threshold at the time of driving but produces a test result above 0.08 percent when tested at a later time. In these cases, the testimony of a qualified toxicologist can be absolutely critical in showing why the defendant was not driving with a BAC of 0.08 percent or higher.

Many toxicology experts are highly experienced in dealing with the blood testing process and some may have been employed by law enforcement crime laboratories during their careers. These experts can testify regarding the reliability of the blood testing process and what errors may have occurred that threaten the integrity of the defendant’s blood sample.

California law requires that a portion of the defendant’s blood sample be set aside for independent testing. The defense can request a blood split order and can have the defendant’s blood retested at an independent laboratory. If the results of the blood split testing are favorable, the defense may need to call a toxicologist from the lab to testify regarding the results of retesting.

The defense can also call a toxicology expert to testify during the driver’s DMV administrative hearing. A toxicologist can testify regarding the calibration and maintenance records of the breath testing device and can explain to the DMV hearing officer why a driver’s BAC was under 0.08 percent at the time of driving as the result of a rising blood alcohol level. In many cases, the testimony of a toxicologist can result in the driver’s suspension being set aside.

Michael Kraut is outstanding! He genuinely cared about my case and instructed my mom and I throughout the entire process. He was very clear on what he needed in order to receive the best results. He kept us updated until the end. I thank him so much for getting my charges rejected. I highly recommend him to anyone with legal needs! Shaquan Thomas
★★★★★
I contacted Michael with concern for my personal and business reputation. He was very reassuring and confident the entire time. After about 3 weeks it was determined that no charges were being filed by any agency and I was in the clear of any investigation. One thing that is amazing is just how FAST Michael is at replying to phone calls, texts, and even emails! We are talking under 30 minutes in most cases. That is unheard of for most attorneys! Michael is incredible and not your typical run of the mill attorney. For best results hire him if you feel like you might be under investigation or could face charges. Even if you know you are innocent it is best to take care of the smoke before it becomes a fire. Brad

Michael Kraut is-hands down-the best criminal defense attorney and I can't begin to thank him for all that he did for me and my family. I reached out to him in the middle of the night and less than a couple hours later, he had gotten back to me and scheduled a meeting. He's a no-nonsense attorney who knows how to get the job done! From the second we retained him, I had peace of mind in knowing that we were in the best hands possible. If Michael Kraut couldn't get it done, I knew that it couldn't be done at all. You can't put a price tag on your freedom. He was worth every single penny. Lida

Michael Kraut - I cannot thank you enough for all that you did for ​my son. When I came to you I read that you used to be a district attorney but I never knew how much that meant until I watch you in court. I knew it took 3 months but the final day when I heard the judge say that all charges were dismissed it was all worth it! I will always be grateful for all that you did for us. A.N.
