If a person accused of DUI refuses to submit to field sobriety exercises or to submit a breath sample a common concern is whether the refusal can be used against the DUI Defendant in Court. As to the driver's license, being deemed to have refused will cause an automatic suspension unless a review hearing is requested and won at the Department of Highway Safety & Motor Vehicles (DHSMV).
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.
In DUI defense a common question or problem involves the "ignition interlock device". The law on the ignition interlock device states that the Department of Highway Safety and Motor Vehicles "shall require the placement of a department-approved ignition interlock device for any person convicted of committing an offense of driving under the influence as specified".
Arrests and the resulting criminal accusations happen every day. Common questions are how can they arrest when there are conflicting stories or can they arrest for whatever just happened. Unfortunately, that is the wrong question. If someone was just arrested, then the answer is yes the cops can and in fact they did just make that arrest. Now the accused has to defend themselves but the only place that happens is at a trial and that will not be for several months.
