What is the purpose of turn signals?

The purpose of turn signals is to communicate your intentions to other drivers. When a driver activates a turn signal, it clearly indicates to other road users when they are planning to make a turn or change lanes. This communication helps create a safer driving environment by allowing other drivers and pedestrians to anticipate your actions on the road. By signaling, you reduce the chances of misunderstandings or accidents that may occur if other drivers are unaware of your intended movements.

While turn signals can also play a role in warnings for lane changes and may indirectly affect pedestrian behavior, their primary and most important function is to facilitate clear communication about your driving intentions to everyone on the road.
