Phase 3 for DUI procedures refers to which activity?

Phase 3 for DUI procedures refers to which activity?

• A. Pre-arrest screening (SFST, Portable breath test)
• B. Vehicle in motion (Justification for stop)
• C. Post-arrest chemical tests
• D. Administrative processing

Answer: (A)

Phase 3 focuses on screening a driver for impairment before making an arrest. In this stage the officer uses standardized field sobriety tests and, where allowed, a portable breath test to quickly assess whether there is probable cause to arrest for DUI. The results help determine if the driver shows signs of impairment and guide the officer’s next steps, all happening after the traffic stop but before formal arrest. This distinguishes it from the initial stop itself and from post-arrest chemical tests or administrative processing that occur later.
