There are very specific procedures law officers must follow when making any arrest or stop. A violation of these regulations constitutes a violation of the arrested person’s constitutionally granted rights.

One common point of contention in DUI cases is whether the arresting officer properly informed the suspect of his/her Miranda rights. The manner in which the police officer determined the suspect’s sobriety, and the accuracy and state of maintenance of the equipment used to do it are also commonly disputed.

If a law officer fails to follow the appropriate procedures, prosecution of the defendant can often be blocked. An effective DUI attorney will be highly proficient in exploiting procedural transgressions by police officers to obtain optimal outcomes for clients.
