DWI detection is defined as ______________.

DWI detection encompasses the entire process of identifying and collecting evidence related to driving while intoxicated. This includes not only the initial observations of a driver's behavior and the circumstances that may suggest impairment but also the methods used to gather corroborating evidence, such as field sobriety tests, breathalyzer tests, and other assessments made by law enforcement.

This comprehensive approach allows officers to build a case that supports the conclusion of impaired driving. It is vital for ensuring that the evidence collected is thorough and can withstand legal scrutiny. In contrast, other options like roadside testing, arrest procedures, or trial methods represent only specific aspects of the DWI process rather than the holistic view that DWI detection includes.
