**Maneuvers** in driving can alter the normal circumstances of traffic. This is because, when performing a maneuver, such as entering a road, it is necessary to observe, signal, and execute it in a way that does not endanger other vehicles or pedestrians.

- **Yielding**: When entering a road, you must yield to vehicles already circulating, which may require you to stop or adjust your speed. This alters the normal flow of traffic, as other drivers must be attentive to your merging.

- **Necessary stops**: Sometimes, it is necessary to stop the vehicle due to emergencies, traffic jams, or instructions from signals or traffic officers. These stops also alter normal traffic, as they can cause interruptions or changes in circulation speed.

- **Dangerous stops and parking**: Parking or stopping in inappropriate places can block the passage of other vehicles or impede maneuvers, which alters normal traffic. For example, parking near a continuous line or in a place that prevents other vehicles from turning.

In summary, any maneuver, stop, or parking can modify the normal conditions of traffic, so it is important to perform them with caution and following safety regulations.
