What phase is the pre-arrest screening considered in the DUI investigation process?

The pre-arrest screening is considered part of Phase Two in the DUI investigation process. This phase occurs after the initial contact with the suspect but before any arrest is made. During this phase, the law enforcement officer assesses the driver's behavior, physical condition, and whether there is probable cause to believe that the driver is impaired.

In this context, the pre-arrest screening typically involves administering field sobriety tests and potentially a preliminary breath test. The purpose is to gather sufficient evidence to determine whether an arrest for DUI is warranted. Officers look for signs of impairment, such as slurred speech, erratic behavior, or difficulties in performing tasks that reflect a driver’s coordination and judgment capabilities.

Understanding this phase is crucial for ensuring that the officer follows proper procedures in making an arrest, which can affect the legal outcomes for the suspect and the integrity of the DUI investigation as a whole.
