In OUI procedures, what phase involves assessing the driver’s behavior when the vehicle is in motion?

In the context of OUI (Operating Under the Influence) procedures, the phase that involves assessing the driver’s behavior when the vehicle is in motion is crucial for determining any impairment. This phase, referred to as "Vehicle in Motion," focuses on observing how a driver operates the vehicle. Key indicators during this phase include erratic driving patterns, failure to maintain lane position, and any other suspicious maneuvers that suggest the driver may be impaired. The assessment during this time provides the initial evidence necessary for officers to justify stopping the vehicle and further investigation.

The other phases, while important, occur at different stages of the OUI process. "Field Sobriety Testing" occurs after the vehicle has been stopped and involves specific tests designed to evaluate the driver’s physical abilities and coordination. "Personal Contact" refers to interaction with the driver after the stop, where officers can observe behaviors, such as speech and the odor of alcohol, but this happens after the vehicle is no longer in motion. "Post-Arrest Processing" takes place after an arrest has been made, involving paperwork and formal procedures that occur once the situation is under control. Each of these phases builds on the assessments started during the "Vehicle in Motion" phase, making it a foundational part of
