When must you use your turn signals?

Using turn signals is a critical component of safe driving and effective communication on the road. The correct answer highlights that turn signals should always be used when changing lanes or turning. This practice helps inform other road users—drivers, cyclists, and pedestrians—of your intentions, thereby reducing the risk of accidents.

By signaling, drivers provide essential information that allows others to anticipate their actions, enhancing overall traffic safety. It is particularly important in situations where lane changes or turns can create potential conflicts with other vehicles or road users.

In contrast, relying on the presence of other vehicles or deciding to signal only when one feels it is necessary can lead to confusion and increase the likelihood of accidents. Forcing drivers to signal only at intersections or only when other vehicles are present undermines the clear communication that signals provide on the road.
