What action should be taken regarding signaling before making a turn?

Signaling is a crucial part of safe driving, particularly before making turns. The correct approach is to signal at least 4 seconds before the turn. This allows other drivers, pedestrians, and cyclists to be aware of your intention to change direction, ensuring that they have adequate time to react. It promotes safety on the road by reducing the likelihood of misunderstandings or accidents resulting from sudden moves.

The specified time frame of 4 seconds gives a clear indication that the driver has planned ahead, fostering a culture of communication and predictability on the road. This practice supports smoother traffic flow and enhances overall road safety for everyone involved.

In contrast, signaling briefly before turning does not provide enough time for other road users to notice your intention. Not signaling at all unless it's deemed necessary can create confusion and increases the risk of collisions. Lastly, only signaling in the presence of other vehicles could lead to dangerous situations where turning actions are not communicated to pedestrians or cyclists, who also need awareness of vehicle movements.
