In OWI detection, which phase primarily involves evaluating the driver's actions upon stopping the vehicle?

The chosen answer pertains to the phase in which officers assess the behavior of the driver immediately after the vehicle has been stopped. During this phase, law enforcement officers observe the driver's mannerisms, expressions, and any potential signs of impairment. It is during personal contact that interactions such as questioning the driver about their drinking or drug use, assessing their coordination, and looking for indicators of intoxication take place. This evaluation is crucial as it informs the officer’s subsequent decisions regarding whether further tests or actions, such as an arrest for operating while intoxicated (OWI), are warranted. Proper assessment during this phase can lead to identifying impaired driving effectively.
