What is the primary purpose of using turn signals while driving?

The primary purpose of using turn signals while driving is to alert other drivers of your intentions. This communication tool is essential for maintaining safety on the roads, as it informs surrounding drivers and pedestrians of your planned maneuvers, such as turning or changing lanes. Effective use of turn signals helps to prevent accidents by ensuring that everyone on the road is aware of each other's actions, allowing all road users to anticipate and respond appropriately.

While other choices may have some relevance—such as compliance with vehicle regulations, which is important to maintain lawful driving practices—none fulfill the critical role of providing information to others on the road as effectively as using turn signals. Making a vehicle look better or saving fuel does not pertain to the primary function of turn signals; their main role is communication for safety and proper traffic flow.
