What is the purpose of using turn signals?

Using turn signals is essential for communicating your intentions to other drivers on the road. When you indicate that you plan to turn or change lanes, you provide important information that helps other drivers anticipate your actions, allowing for smoother traffic flow and reducing the risk of accidents. Proper use of turn signals enhances road safety by ensuring that all road users are aware of each other's movements, which is particularly vital in busy traffic situations.

The other choices do not accurately capture the primary function of turn signals. While making a vehicle look stylish may be a consideration for some, it is not a reason for using turn signals. Similarly, while fuel efficiency is an important aspect of driving, it is not influenced by the use of turn signals. Lastly, turn signals do not directly signal to pedestrians to stop; they are primarily aimed at other vehicles. Thus, the main purpose remains communication of intentions to enhance overall road safety.
