What is the purpose of using turn signals?

The purpose of using turn signals is to communicate your intentions to other drivers on the road. By signaling, you notify others of your forthcoming actions, such as turning or changing lanes, which helps to enhance safety and reduce the likelihood of accidents. When drivers are aware of your plans, they can adjust their driving accordingly, allowing for smoother traffic flow and minimizing confusion about your movements on the road. This practice is a fundamental aspect of defensive driving, as it fosters awareness and cooperation among all road users, contributing to a safer driving environment.
