When overtaking another vehicle, it is important to **return to the right lane as soon as possible**. This should be done without disturbing the overtaken vehicle or forcing other drivers to change their speed.

- **Completion of the overtaking:** Once you have overtaken, you must indicate your intention to return to the right lane using the appropriate lights. This ensures that other drivers are aware of your movements and can adjust their driving if necessary.

- **Safety and traffic flow:** Quickly returning to the right lane helps maintain traffic flow and reduces the risk of accidents. Staying in the left lane longer than necessary can obstruct the passage of other vehicles wishing to overtake.

- **Consideration towards other drivers:** By returning to the right lane without disturbing the overtaken vehicle, you demonstrate courtesy and respect towards other drivers, which is essential for safe and harmonious driving.

In summary, the key is to return to the right lane quickly and safely, ensuring you do not interfere with other vehicles on the road.
