El Cajon DUI Defense Attorney
Breath and Blood Tests
If you have failed or refused a breath or blood test and it resulted in a DUI, an experienced El Cajon DUI lawyer at DUI Crew can assist you and fight your case.
In order to convict a person of driving under the influence in El Cajon, law enforcement and the prosecuting attorney uses a driver’s breath or blood test results as evidence against them in a court of law. A breath test, blood test or sometimes even a urine test is used to determine a driver’s blood alcohol concentration. If the driver of the vehicle is driving while their blood alcohol concentration is .08% or more, they can be charged with drunk driving. Underage drivers can have their license suspended if they are determined to have a BAC over .01%, and commercial drivers when driving with a BAC of .04% or more.
About Breath Tests and Blood Tests in El Cajon
A breath test is normally administered by the driver blowing into a breathalyzer that calculates the concentration of alcohol in the blood by the breath sample. Breath tests are often considered to be less reliable than a blood test and may have several problems, affecting the results. An El Cajon DUI attorney can bring these results to question in court. For example, the breathalyzer machine needs to be calibrated every so often and according to state standards, to ensure that the results are accurate for use in court. If the device was not calibrated by standards, the El Cajon DUI attorney may be able to use this to help win your case.
Administration of a blood test is done by taking a blood sample from the suspect and then determines the concentration of the driver’s blood alcohol (BAC). Although blood tests are more accurate than breath tests, blood tests have their own faults as well. They can be mishandled, administered porly or mishandling by any other way. Your El Cajon DUI attorney may be able to use this to help win your case.
