What is required for an officer to lawfully arrest a suspect in a DUI case?

An officer must have probable cause to believe that a suspect is impaired in order to lawfully arrest them in a DUI case. Probable cause is the legal standard that allows law enforcement to take action based on the facts and circumstances known to them at the time. In DUI cases, probable cause typically arises from observing signs of impairment, such as erratic driving behavior, the smell of alcohol, slurred speech, or physical indicators that suggest the driver is under the influence of drugs or alcohol.

When officers establish probable cause, they can then proceed with an arrest, ensuring that they are acting within the boundaries of the law and protecting the rights of the accused. This legal standard is crucial as it upholds the principles of due process while allowing law enforcement to address potentially dangerous driving behavior effectively.

Other options do not meet the legal requirements or relevance necessary for an arrest in this context, focusing instead on unrelated factors such as wealth or procedural errors.
