DUI Chemical Tests

Aggressive Defense Against DUI Charges in Corona

One of the main elements used to determine intoxication is a chemical test. There are three types of chemical tests used in DUI cases: breath tests, blood tests, and urine tests. Although these would seem to be indisputable in a court of law, the fact of the matter is that they are often successfully challenged. My name is Michael J. LaCilento and I am known for my aggressive legal representation against DUI charges in Corona. Let me take on your DUI case today!

Breath Test

A breath test, commonly used in DUI cases, determines a person's blood alcohol content (BAC) level based on their breath alcohol content level. This can often provide incorrect readings, as the result of a test is based on average statistics. While a breath test may indicate a BAC of 0.08% or more, the actual statistic may be much lower, depending on the individual.

Challenges to a DUI charge can take into account the defendant's weight, sex, and metabolism, as well as problems during the breath testing process, a malfunctioning test machine, and their status at the time they were behind the wheel.

Blood Test

Although a blood test is an attempt to directly determine a person's BAC, these tests are frequently inaccurate. I can help you challenge these tests in a number of ways. For example, you can have the evidence from a blood test dismissed in court if we prove that the sample was collected incorrectly. In addition, if your blood was stored improperly, the amount of alcohol in your blood could have risen prior to testing, resulting in a faulty DUI charge. Finally, any number of improper testing methods could have led to a DUI where there were no real grounds for the charge.

Urine Test

The urine test is the least accurate indicator of a person's blood alcohol content level. As with the breath test, the results determined from a urine sample are based on an average ratio—in this case, the amount of alcohol in your urine is assumed to indicate the amount of alcohol in your blood. Fortunately, there are many flaws in this assumption. The amount of alcohol present in a sample depends on how long the alcohol had accumulated before your test. The number can be inaccurately high or low depending on this factor or the amount of non-alcoholic liquid you had consumed prior to testing. Though a second urine sample is used to balance the testing process, the test is still not always accurate.

You can fight your charges!

Though any of these testing methods may have been used to charge you of DUI, you are not hopeless. As discussed, all of these tests have flaws and often render inaccurate readings. If you have been charged with drinking and driving, I can help. I have over 20 years of experience as a Corona DUI attorney and can help you combat the evidence used against you.
