Under what condition can vehicle 2 make a turn?

The condition that allows vehicle 2 to make a turn is when it is safe to do so. This means that the driver of vehicle 2 must assess the traffic situation, including the presence of other vehicles, pedestrians, and road conditions, before executing the turn. Safety is a critical factor in driving, ensuring that maneuvers are carried out without causing accidents or disrupting the flow of traffic.

While waiting for vehicle 3 or vehicle 1 to pass may seem like a reasonable action, the responsibility ultimately lies with the driver of vehicle 2 to judge whether the moment is indeed safe for turning. This consideration involves observing the actions of other vehicles and being vigilant about potential hazards, including approaching traffic or obstacles. Keeping safety as the priority aligns with defensive driving practices, promoting not only the driver's safety but also the safety of others on the road.
