What important consideration must be made during vehicle stops related to OUI?

During vehicle stops related to Operating Under the Influence (OUI), initial observations made by the officer are crucial to the assessment and determination of intoxication. These observations can include the driver's behavior, the manner of driving, and any physical indications of impairment, such as slurred speech or the smell of alcohol. Early insights gathered during the stop can greatly influence the officer's decision to proceed with further testing or inquiries about OUI.

While factors like time of day, weather conditions, and the presence of passengers are relevant to some extent, they are secondary when considering the immediate evaluations that the officer can make upon stopping the vehicle. The officer's initial observations directly inform the actions taken in response to suspected OUI, making this aspect the most critical consideration during such stops. Understanding these observations allows officers to build a foundation for their interactions and assessments throughout the encounter.
