Step-by-step explanation:
Yes, it is necessary to signal before returning to your lane after passing another vehicle.
Signaling is an important safety measure that alerts other drivers of your intent to change lanes. By indicating your intention to return to your lane, you are giving other drivers the opportunity to adjust their speed and position to accommodate your movement, reducing the risk of a collision.
For example, let's say you are driving on a multi-lane highway and you have just passed a slower vehicle in the left lane. To safely return to the right lane, you should use your turn signal to indicate your intention to change lanes. This signal lets the driver behind you know that you are planning to move over, allowing them to maintain a safe following distance.
