What is the first phase of OUI enforcement?

The first phase of Operating Under the Influence (OUI) enforcement is focused on the vehicle in motion. This initial phase involves observing the behavior of a driver while they are operating their vehicle. Law enforcement officers typically look for specific signs of impaired driving, such as erratic lane changes, failure to obey traffic signals, or unusual speed patterns. These observations are crucial in establishing probable cause for a stop and further investigation into whether the driver is impaired.

Detecting signs of impairment during this phase sets the foundation for subsequent actions, such as personal contact with the driver and pre-arrest screening. Recognizing the potential indicators of impaired driving early in this process helps officers take appropriate steps for ensuring road safety and conducting a thorough investigation.
