What is the purpose of using turn signals?

Using turn signals is essential for communicating your intention to turn or change lanes to other drivers on the road. This practice promotes safety and helps prevent accidents by providing clear warnings about your actions. When you signal your intention to turn or change lanes, it allows other road users to anticipate and respond appropriately, creating a more organized flow of traffic.

In addition to enhancing safety, the use of turn signals is not about indicating speed, warning drivers of a stop, or signaling pedestrians to cross. Each of those actions relies on different forms of communication or signals. For instance, speed is conveyed through your vehicle's movement and is not something that can be effectively communicated with a signal. Similarly, using your brakes, hazard lights, or other means is more appropriate for stopping. Pedestrian signals typically involve crossing signals or visual indicators specifically designed for their use, rather than turn signals meant for vehicular communication.
