What is the purpose of turn signals when driving?

Turn signals are an essential component of safe driving, as their primary purpose is to communicate your intentions to other drivers on the road. When you activate your turn signal, it alerts surrounding vehicles and pedestrians about what maneuver you plan to execute, such as a turn or changing lanes. This communication helps reduce confusion, preventing accidents by ensuring that others are aware of your movements and can react accordingly.

The other options, while seemingly related to driving, do not capture the full and correct function of turn signals. They limit the context in which signals should be used, failing to encompass the broader aspect of communication on the road essential for safe driving practices.
