What is the role of turn signals when driving?

Turn signals play a crucial role in communicating a driver's intentions to other road users. When you use turn signals, you are effectively informing drivers, cyclists, and pedestrians of your next move, whether it’s to turn or change lanes. This communication is vital for maintaining safety on the road, as it helps prevent misunderstandings and collisions.

By signaling properly, you allow others to anticipate your actions, which contributes to smoother traffic flow and enhances overall road safety. For instance, if you are preparing to turn left at an intersection, signaling lets the drivers behind you know to slow down or reposition themselves accordingly. This mutual awareness can significantly reduce the risk of accidents and create a more organized driving environment.

The other choices provided misinterpret the function of turn signals. For example, they do not serve to show speed, alert pedestrians exclusively, or improve fuel efficiency, focusing solely on the pivotal role of intention communication.
