To carry out an overtaking maneuver safely and correctly, it is important to follow certain steps and properly use the **direction-indicator lights**.

- **Direction-indicator lights**: These yellow, flashing lights are used to warn other drivers that you are going to change direction or lane. It is mandatory to switch them on before performing any lane-change or direction-change maneuver.

- **During the overtaking**: When overtaking, you must move into the left-hand lane and keep a safe distance from the vehicle you are overtaking. It is crucial to ensure the lane is clear and that you can return to your original lane without putting other drivers at risk.

- **Completion of the overtaking**: Once you have completed the overtaking, that is, when you are already in the left-hand lane and have passed the vehicle you overtook, you must switch on the direction-indicator lights to signal that you are going to return to your original lane. Only after having completed this movement may you turn off the direction-indicator lights.

Therefore, the direction-indicator light must be turned off **when you have finished the maneuver**, that is, after you have returned to your original lane safely.
