What is the first phase in DUI detection?

• A. Vehicle in motion
• B. Personal contact
• C. Pre-arrest screening
• D. Field sobriety testing

Answer: (A)

The first phase in DUI detection is the observation of the vehicle in motion. This initial phase involves law enforcement officers noticing behaviors or driving patterns that may indicate impaired driving. During this time, officers look for signs such as swerving, abrupt stops, excessive speed, or driving too slowly. Any of these indicators can provide the officer with reasonable suspicion to initiate a traffic stop. Observing the vehicle in motion is critical because it sets the foundation for the subsequent phases of DUI detection. Once the vehicle is stopped, personal contact can take place, where officers assess the driver’s demeanor and perform additional evaluations, but this occurs after the motion phase has already indicated potential impairment. In essence, the vehicle in motion phase allows officers to determine whether further investigation is warranted regarding the driver's condition.
