What is the main reason for using turn signals?

The main reason for using turn signals is to communicate your intention to other drivers. This communication is crucial for road safety, as it allows other motorists and pedestrians to anticipate your actions on the roadway. By signaling your intentions, such as turning or changing lanes, you help maintain order and prevent accidents, as others are made aware of your intended maneuvers.

Signaling effectively allows drivers to make informed decisions about their own movements in relation to yours, promoting a safer driving environment for everyone involved. While other options might involve aspects of driving behavior or vehicle operation, none capture the primary goal of turn signals, which is to convey clear communication on the road.
