When can vehicle 3 proceed in a traffic sequence?

In the context of traffic sequences, vehicle 3 should only proceed after vehicles 1 and 2 have moved. This ensures that traffic flows smoothly and safely, respecting the right-of-way rules that govern interactions among multiple vehicles at intersections or merging scenarios. Following the established traffic sequence helps prevent accidents and confusion among drivers, ensuring that each vehicle acts according to the order dictated by traffic signals or road rules.

While options such as stopping completely or waiting for a traffic light to change contribute to safe driving practices, they do not address the specific requirement for vehicle 3 to wait for the preceding vehicles to finish their turns or movements. This cadence is vital for maintaining order on the roadway, especially in environments where multiple vehicles are interacting closely.
