What action is typically not associated with the vehicle in motion phase of detection?

In law enforcement contexts, the vehicle in motion phase involves observing and analyzing the behavior of a moving vehicle to assess whether it is compliant with traffic laws and to identify any suspicious activity. This phase focuses primarily on monitoring the actions of the vehicle and its driver.

Initiating contact is generally considered a separate phase of interaction, usually following the vehicle in motion phase. Once officers have assessed the situation and determined a need to engage with the vehicle or the driver, they would initiate contact. This contact typically occurs after the vehicle has been observed in motion and the officer has assessed various factors such as traffic behavior, speed, and lane changes.

Monitoring speed, observing traffic behavior, and noting lane changes all involve active observation and are key components of understanding the dynamics of the vehicle while in motion. Each of these actions contributes to forming a basis for any necessary further action, whether that's initiating a stop or simply monitoring compliance with the law.
