What is the primary purpose of using turn signals?

Using turn signals is primarily about communication with other drivers on the road. When you signal your intention to turn or change lanes, you inform other road users of your planned actions, which helps to enhance overall safety and coordination in traffic. Proper use of turn signals reduces ambiguity and can prevent accidents, as it allows other drivers and pedestrians to anticipate your movements and react accordingly.

The other options do not align with the primary purpose of turn signals. While making a vehicle look attractive, notifying pedestrians about speed, or increasing fuel economy might be considerations in other contexts, they are not relevant to the function of turn signals in traffic. The core reason for using turn signals remains the need for clear communication while driving.
