When is it essential to use turn signals?

Using turn signals is essential always when making turns or lane changes because they communicate your intentions to other drivers on the road. Signaling provides a clear indication of your movement to those around you, which is crucial for maintaining safety and preventing accidents. By signaling, you make it easier for other drivers to anticipate your actions and adjust their driving accordingly, thereby enhancing the overall safety of the driving environment.

In situations like merging onto highways, while signaling is important, it is not exclusive to that scenario; it is just as important in everyday driving situations such as regular turning and lane changes. This principle promotes consistent driving behavior, allowing all road users to operate with a shared understanding of one another's actions, regardless of traffic conditions.
