What is the purpose of using turn signals?

Answer: B — To indicate intended lane changes and turns

Using turn signals is essential for communicating a driver's intentions to others on the road. When a driver activates a turn signal, it indicates their intent to change lanes or make a turn, providing critical information to surrounding vehicles and pedestrians. This communication helps to enhance safety by reducing the chances of misunderstandings that could lead to collisions. The purpose of turn signals goes beyond merely obeying legal requirements; it is about facilitating safe driving practices and fostering a cooperative driving environment. While some may view turn signals as a formality or compliance with laws, the primary function is to ensure that all road users are aware of a driver's upcoming maneuvers, thereby preventing accidents and improving overall traffic flow.
