DUI Blood Test

It is almost a certainty that a person that is suspected of driving under the influence will be requested to perform a chemical test to determine his or her blood alcohol concentration (BAC). Though breath tests are the norm, law enforcement could also request a blood draw to determine a person's BAC.

Though blood tests are hailed as being more accurate and a sure DUI conviction when the results come back showing a BAC at 0.08 or above, however, this could not be further from the truth.

Errors can occur when a blood test is performed on a person arrested for a DUI offense, and if not properly challenged by an experienced Miami DUI criminal defense attorney, it could potentially cost that person their freedom.

Implied Consent in Miami, Florida

It has been long held that Florida's "implied consent" law could subject any person utilizing roadways within the state to a chemical test to determine their BAC if when they are arrested for a DUI related offense.

In other words, once a law enforcement officer has sufficient probable cause to affect an arrest for driving under the influence ("DUI"), the driver would be legally obligated under Florida law to provide a breath or urine sample to determine the amount of alcohol in his or her system.

Failing to comply with Florida's "implied consent" law would result in the immediate suspension of the person's driver's license. In addition, their refusal could be used against them as evidence in their DUI criminal proceeding.

However, different standards are applied when a law enforcement officer is seeking a blood sample. In Florida, blood can only be taken by force in situations where there was serious bodily injury or death caused by a driver that is presumed to be under the influence of alcohol or a controlled substance.

In a recent Supreme Court ruling under Missouri v. McNeely, No. 11-1425, the Court ruled that in order for an officer to obtain a forced blood sample, a warrant must first be obtained unless an "exigent emergency" is present.  This ruling's effect on Florida DUI cases and future law enforcement protocols is still to be determined.

If you had your blood withdrawn from your body by force after a DUI arrest, you need a knowledgeable Miami criminal defense attorney to review your arrest and the chemical testing results immediately.

Defenses to a Florida Blood Test

There are several ways the validity and admissibility of a Florida DUI blood test can effectively be challenged, rendering it void.

If the prosecution is unable to establish the test was conducted in full compliance with Florida's Administrative Code, the results may be suppressed. Some common examples of a blood test not meeting the standards established by Florida law include:

  • Break in the Chain of Custody,
  • Blood Sample not Properly Preserved,
  • Untrained or Uncertified Person Withdrew Blood,
  • Improper Collection,
  • Alcohol Contamination During Sterilization of Withdraw Site, and
  • Blood Sample not Properly Preserved

Applicable defenses may also arise when the defendant's legal rights were violated during the course of the DUI stop and subsequent investigation, such as:

  • Lack of Reasonable Suspicion to Initiate Traffic Stop,
  • Lack of Probable Cause to Believe the Defendant was Under the Influence of Alcohol or a Controlled Substance,
  • Lack of Probable Cause to Perform the DUI Arrest,
  • Misstatement or Misinterpretation of the Law, or
  • Invalid Consent

Independent Blood Tests in Miami, Florida

A person that has been arrested for a DUI offense and complied with a chemical test to determine their BAC has the legal right to have an independent chemical test performed at their own expense.
Florida Statute 216.1932(1)(f)(3) states that a person who has submitted to a chemical test of his or her breath, urine, or blood may acquire the services of a trained professional to perform an independent breath, urine, or blood test at his or her own expense.
The results of an independent blood test could be beneficial if they yield results that differ from the results allegedly produced by law enforcement.
