What are the three phases in DUI detection?

The selection identifies the three critical phases in DUI detection, which are essential for law enforcement officers when assessing potential impaired drivers. The phases include:

1. Vehicle in Motion: This phase involves observing the vehicle's operation patterns. Officers look for specific behaviors indicative of impaired driving, such as swerving, speeding, or erratic stopping.

2. Personal Contact: Once the vehicle is stopped, the officer interacts with the driver to gather further information. This includes observing the driver's demeanor, speech, and any potential signs of impairment, such as the smell of alcohol or the presence of drugs.

3. Pre-arrest Screening: During this phase, officers typically conduct field sobriety tests and determine whether there are sufficient grounds to arrest the driver for DUI. The tests assess the driver's physical and cognitive ability to safely operate a vehicle.

This answer is correct because it outlines a systematic approach to DUI detection that aligns with law enforcement training standards and helps establish probable cause for arrest if necessary. Understanding these phases is crucial for officers to effectively and safely identify impaired drivers while ensuring that legal protocols are followed during the process.
