What is a key reason to use turn signals?

Using turn signals is essential for communicating your intentions to other drivers on the road. When a driver activates their signal, it informs other road users of their intended actions, such as turning or changing lanes. This communication helps promote safety and reduces the likelihood of accidents by ensuring that other drivers are aware of the upcoming maneuvers.

While fuel consumption, signaling for permission to merge, and indicating speed adjustments may have their own relevance in driving, they do not serve the primary purpose of turn signals. The main goal of using turn signals is to facilitate clear communication, which is critical in maintaining a safe driving environment for everyone.
