# Explanation: Signaling a Lateral Displacement
The correct way to signal a lateral displacement is to use **the direction indicator lights as the main means**. However, if the vehicle does not have these lights or they fail, **the hand signal with the arm** can be used as an alternative. This combination of options ensures that other drivers are informed of your intention to change lanes, prioritizing road safety.
