What is the purpose of using turn signals?

The primary purpose of using turn signals is to indicate your intention to turn or change lanes. This communication is essential for roadway safety, as it informs other drivers and pedestrians of your intended movements, allowing them to adjust their behavior accordingly. By signaling your intentions, you help prevent accidents and ensure a smoother flow of traffic, as others are made aware of what you plan to do next on the road. This practice is a fundamental part of defensive driving and is required by law in most jurisdictions, including New South Wales. The use of turn signals not only helps in maintaining safety but also promotes courtesy among road users.
