# Signaling Maneuvers
The correct way to indicate a maneuver is by using **light signals first** (turn signals), which are the main and most visible method for other drivers. In case the turn signals do not work or are not visible, you must use **arm signaling** as an alternative. This combination ensures that your intention is clear and safe for all road users.
