Challenging the way the police officer handled the stop. A driver cannot be pulled over if the officer doesn’t have a valid reason to believe that the driver is in violation of a traffic law or other law. DUI checkpoints may be an exception, however, and drunk drivers may find themselves arrested and facing penalties for a Florida DUI.
Challenging the stop itself. A police officer must have a reason to justify pulling a car over and ultimately making an arrest for DUI in FL. Many suspected drunk drivers are pulled over after the officer observes a traffic violation (speeding, running stop sign) or notices erratic driving behavior that puts other drivers at risk.
A Ft. Lauderdale DUI lawyer may challenge the legitimacy of a stop and ultimately a DUI in FL if the driver was not cited for any other traffic violation and did not pose a risk to other drivers before being pulled over.
Challenging the use of field sobriety tests as evidence. The standard field sobriety tests were evaluated in 2005 study published in the Journal of Forensic Science by Dr. Michael P. Hlastala of the University of Washington. The research found that the accuracy of a field sobriety test is only about 30-60 percent when drivers have a blood alcohol concentration (BAC) at 0.06 – 0.08, compared to higher or lower BACs.
Challenging conditions at time of arrest. Poor weather can cause erratic driving behaviors; uneven pavement can cause a sober person to fail a field sobriety test. Medical conditions such as Parkinson’s disease, diabetes, and speech impediments can also cause a person to appear intoxicated or have false positive chemical test results.
A Ft. Lauderdale DUI lawyer may call upon an expert witness who may testify as to whether a medical condition may have led to false results and ultimately the charge of DUI in FL.
Challenging the use of a Breathalyzer as evidence for arrest. For the results of a Breathalyzer test at the scene to be considered valid, the driver should be observed continuously for a minimum period, such as twenty minutes, prior to a breath test.
Breath testing is subject to various inaccuracies, including miscalibrated testing units and insufficient training of officers. The Ft. Lauderdale DUI lawyer may challenge the use of the device when arguing against Florida DUI charges.
Challenging video evidence. Video evidence of an arrest and conviction is often admitted as evidence in a Florida DUI case. Dashboard video may record police communications and interactions that show due process was violated, or may contradict a police officers’ report.
Failure to preserve these tapes upon request may render any related evidence invalid. Video of driver conduct at a police station may also show a sober, competent individual, contrary to police descriptions of the arrest for DUI in FL.
Challenging blood tests. Blood tests must be administered by a licensed professional in an appropriate environment. Any conduct that may taint the sample such as contaminated drawing materials or improper procedure may render the results inaccurate. A Ft. Lauderdale DUI lawyer may call upon an expert to help evaluate the validity of the tests used to establish DUI in FL.
Challenging conviction based on violation of rights. Upon an arrest for a Florida DUI, or any other charge, the defendant must be made aware of his or her rights, known as a Miranda Warning. If these rights are not given to the driver upon arrest, any statements made during the arrest may become void as evidence.
Challenging the arresting officer’s credibility. The conduct history of the arresting officer may be called into question if your Fort Lauderdale DUI lawyer believes he/she may have handled a drivers’ arrest improperly. The arresting officer’s disciplinary record may be used to defend a driver against DUI in FL if the officer has a history of misconduct.
Statements made by a police officer, either verbally or in police reports, may be used to challenge credibility. Misleading statements given at any time from the officer to the defendant regarding the consequences for refusing tests or regarding the driver’s rights may cause the Florida DUI charge to be dropped.
Challenging the use of expert witnesses. Prosecutors may call in expert witnesses to testify on behalf of the state during DUI cases. These expert witnesses must be disclosed or they may be barred from testifying in the trial.
Expert witnesses may be called in by either side of the Florida DUI case to review the validity of breath tests, blood tests and field sobriety tests. The failure of the prosecutor to disclose the state’s expert(s) will cause those witnesses to be barred from testifying against the defendant.
