By obtaining a Florida drivers license you have consented to provide a sample of your breath or blood when requested to do so by a law enforcement officer. Failure to take an approved breath test will result in an extended driver’s license suspension without the benefit of a hardship license. Under some circumstances, refusal to take a breath test may also result in an additional criminal charge and is admissible at trial as proof of your knowledge that you were driving with an unlawful blood alcohol level. Blood tests are often more reliable than breath tests. Requesting that the police draw a sample of your blood for testing, in addition to submitting to a breath test, will satisfy the law and preserve your rights.
