Which scenario would NOT allow an officer to observe the driver operating the vehicle?

The scenario in which an officer would not be able to observe the driver operating the vehicle is when a driver is parking their vehicle. In this situation, the officer may not have a clear line of sight to witness how the driver is handling the vehicle, especially if the maneuver is being performed in a controlled and careful manner.

During parking, the vehicle is stationary and the movement tends to be slow and deliberate, which may not attract the attention of law enforcement. In contrast, the other scenarios involve more dynamic situations where the driver’s actions are likely to be observed by an officer, either due to the urgency of the situation (like in a traffic crash or when requesting assistance) or because the driver may be visibly impaired or incapacitated (as in being passed out behind the wheel).
