When should you signal before changing lanes?

Signaling before changing lanes is essential for maintaining safety on the road, and it should always be practiced, regardless of the traffic conditions. This action serves multiple purposes: it communicates your intentions to other drivers, ensuring they are aware that you are about to change your position on the roadway. Signaling helps prevent misunderstandings and potential accidents.

Even in light traffic, other drivers, cyclists, or pedestrians could be affected by your lane change, emphasizing the importance of indicating your intentions. Relying on situational factors, like heavy traffic or the presence of specific vehicles such as motorcycles, does not guarantee that all road users are aware of your actions. Therefore, making it a habit to always signal not only demonstrates courtesy towards others but also reinforces safe driving practices.
