What is the final focus of the OWI detection process before making an arrest?

The final focus of the OWI detection process before making an arrest is pre-arrest screening. This stage is crucial as it involves assessing the driver's condition through a combination of cognitive and physical tests. During pre-arrest screening, law enforcement officers observe the driver's behavior, check for signs of impairment, and may administer standardized field sobriety tests. This phase allows officers to gather sufficient evidence to justify an arrest based on their observations and test results.

Personal driver interaction precedes this stage but is not the conclusive focus. Vehicle compliance checks and vehicle in motion analysis are also vital elements of the overall detection process but occur earlier on in the sequence or in conjunction with the initial approach to the driver. Pre-arrest screening consolidates the information gathered to support the decision on whether an arrest for OWI is warranted.
