What is one function of turn signals when driving?

Turn signals serve the important function of communicating your intentions to other drivers on the road. When you signal before a turn or lane change, it provides a visual cue that helps others anticipate your actions, promoting safer driving. This communication is crucial in preventing accidents, as it allows following vehicles to adjust their speed or position accordingly, helping to ensure a smoother flow of traffic.

While turn signals are designed to alert other drivers, they do not indicate vehicle speed or activate emergency brakes, nor are they intended to alert pedestrians exclusively. Their primary purpose is to enhance overall road safety by facilitating clear communication between motorists.
