When must you use your turn signal?

Using your turn signal when changing lanes or making a turn is crucial for road safety and communication with other drivers. The primary function of a turn signal is to indicate your intentions to other road users, which helps to prevent accidents by alerting them when you are about to make a maneuver.

For example, when changing lanes, signaling well in advance allows other drivers to adjust their speed or position accordingly. Similarly, when making a turn at an intersection, using your turn signal informs pedestrians and other vehicles of your intended direction, enhancing overall awareness and safety on the road.

While signaling is also important under various circumstances such as making a u-turn and when parking, the most frequent and essential times to use a turn signal occur during lane changes and turns since these actions directly affect the movement of other vehicles and pedestrians in close proximity.
