What must the turn indicator be used for?

The turn indicator, also known as a turn signal, serves several critical functions to ensure safety and communication on the road. It is essential for drivers to signal their intentions clearly to other road users. The correct answer encompasses a comprehensive understanding of its purpose.

Using the turn indicator for turns is fundamental; it informs other drivers and pedestrians that you are about to change direction. This communication is vital for preventing misunderstandings and accidents at intersections.

Additionally, signaling when passing another vehicle or changing lanes is equally important. It alerts surrounding traffic to your movements, allowing them to anticipate and adjust accordingly, which is a crucial aspect of safe driving.

The use of turn indicators when leaving a traffic circle is also necessary to indicate to other road users that you are exiting. This ensures that vehicles already in the circle and those waiting to enter are aware of your actions, contributing to the overall flow of traffic and reducing the risk of collisions.

By recognizing that the turn indicator should be used in all these scenarios, drivers can promote a safer driving environment. Thus, indicating that all choices regarding its use are correct reflects a full understanding of the turn indicator's role in road safety and communication.
