What is the purpose of using turn signals?

Using turn signals is essential for communicating your intentions to other drivers on the road. When a driver activates their turn signal before changing lanes or making a turn, it serves as a visual cue that informs surrounding motorists of their upcoming actions. This communication helps prevent misunderstandings and reduces the risk of accidents, as other drivers can anticipate the movement and respond appropriately.

While indicating to pedestrians is important, the primary function of turn signals is to enhance safety and coordination among drivers. Increasing visibility at night is related to headlights and does not pertain to the specific function of turn signals. Additionally, alerting emergency vehicles involves different signals (such as lights and sirens) and is not the primary purpose of turn signals. Thus, the use of turn signals plays a crucial role in promoting safe driving practices and fostering a predictable traffic environment.
