Which action is NOT typically associated with occupants during a traffic stop?

The action that is not typically associated with occupants during a traffic stop is unbuckling their seatbelt while moving. During traffic stops, the standard expectation is that occupants will remain seated and secured with their seatbelts fastened until instructed otherwise by law enforcement. This is primarily for the safety of both the occupants and the officers involved in the stop.

However, situations like exiting the vehicle and running, or exiting the vehicle to approach the officer, are actions that can occur, albeit under different circumstances and often carry different implications regarding safety and compliance. Remaining in the vehicle is also a common response, as it often aligns with the instructions given by an officer during a stop. Therefore, unbuckling a seatbelt while the vehicle is still in motion is not a typical or safe action associated with the expected behavior of occupants during such encounters.
