How many phases are there in a DUI process?

• A. 2
• B. 3
• C. 4
• D. 5

Answer: (B)

The DUI process is commonly understood in three distinct phases. First is the stop and initial contact, where the officer pulls over the vehicle, observes driving behavior, and ensures safety for everyone on the roadway. Second is the investigation phase, during which impairment is further evaluated through observations and standardized field sobriety tests to establish probable cause for a suspected DUI. Third is post-arrest processing, which includes the arrest itself, explaining rights, and ordering or administering chemical testing (breath or blood) and booking, all of which lead toward court proceedings. Each phase has its own clear objective and evidence-collection focus, so three phases best capture the typical flow of a DUI case. Some descriptions merge steps or extend into court procedures, but the standard teaching splits it into stop/contact, investigation, and post-arrest processing.
