New York DWI Arrest Procedures & Field Sobriety Testing Practice Test 2026 - Free DWI Practice Questions and Study Guide

The phases of DWI Detection are critical for law enforcement in identifying impaired drivers through a structured approach. The phases include Vehicle in Motion, which involves the observation of a vehicle's operation; Personal Contact, where the officer interacts with the driver to assess their condition; and Pre-arrest Screening, which consists of evaluating the driver’s physical and cognitive abilities through tests.

Driving Assessment, while it may sound relevant, is not officially recognized as a distinct phase of DWI Detection in standard training protocols. Instead, the actual assessment of driving behavior is encapsulated within the broader phase of Vehicle in Motion and is assessed through the eventual field sobriety tests during Pre-arrest Screening.

This understanding highlights the importance of each defined phase in the detection process and clarifies why Driving Assessment does not stand alone as an established phase within DWI detection methodology.
