Background

Defendant Cesar Rodriguez was stopped for traffic violations. After the officer completed the stop tasks and returned Rodriguez’s documents, Rodriguez stayed in the patrol car and answered questions about his travel plans. The officer then called a drug-sniffing dog, which alerted, leading to the discovery of fentanyl.

The court’s reasoning

The court determined the traffic stop ended when the officer returned the documents and issued a warning. The court found that the officer did not use coercive tactics, the patrol car door remained open, and the officer explicitly told the defendant he was good to go. Because the defendant voluntarily stayed and answered questions after the stop ended, the encounter was consensual.

Once I give this [i.e. warning] to you, you’ll be good to go, okay?

What it means going forward

The ruling clarifies that returning documents and stating a driver is free to go can transform a detention into a consensual encounter, allowing officers to question drivers without reasonable suspicion.
