In a DUI arrest, when a breath test is not available or feasible, or if the circumstances allow, law enforcement may seek a sample of the accused driver's blood to determine a blood alcohol concentration or content (BAC). The question of whether and how the police may take the accused DUI driver's blood has been considered by the United States Supreme Court in the last few years.
There are all kinds of urban myths in DUI / DWI law. In the context of a Florida DUI, a Florida appellate court has interpreted Florida law as allowing a conviction to a New York charge of driving while alcohol impaired (DWAI), section 1192 (1), to be used to enhance a Florida DUI. In addition, a conviction to a New York DWAI can be used for purposes of suspending a Florida driver's license. This strikes many as odd since the New York offense of DWAI is specifically not a DUI pursuant to New York law. Many people are surprised to learn that what one state does not consider a DUI is treated as such in Florida.
To prove a criminal case of vehicular homicide in Florida, the State must prove reckless driving plus one additional fact, the death of a person. Vehicular homicide, simply stated reckless driving plus a death caused by the reckless driving.
