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

Using turn signals while driving is primarily about communication. It serves as a means for drivers to indicate their intentions to others on the road. By signaling, drivers can inform vehicles and pedestrians about their upcoming actions, such as turning or changing lanes. This reduces the likelihood of accidents by ensuring that everyone on the road has a clear understanding of what to expect from one another, promoting safer driving conditions.

While other factors like visibility or avoiding fines can be considerations, they do not encapsulate the essence of why turn signals are essential. Making the vehicle more visible doesn't specifically relate to the intention behind the maneuver. Avoiding traffic fines may be a consequence of proper signaling but is not the main objective. Maintaining speed on highways is unrelated to the function of turn signals, which focus on conveying movement intentions rather than speed management. Understanding this key function of turn signals is vital for safe and responsible driving.
