What is the first phase of OUI enforcement?

The initial phase of OUI (Operating Under the Influence) enforcement is focused on observing the vehicle in motion. This phase involves law enforcement officers monitoring driving behaviors that may indicate impairment, such as erratic lane changes, sudden stops, or swerving.

During this stage, officers gather crucial evidence through their observations of how the vehicle is being operated, which sets the foundation for further investigation. If a driver's behavior suggests they may be under the influence, it legitimizes the officer's decision to initiate a traffic stop and proceed to the next steps of enforcement, such as personal contact and field sobriety tests. This phase is essential as it helps to establish reasonable suspicion necessary to engage with the driver and evaluate their state of sobriety further.
