What is the purpose of using directional signals before turning?

Using directional signals before turning serves a crucial purpose in maintaining safety and efficiency on the road. The primary reason for using these signals is to inform other drivers of your intention to turn or change lanes. This communication helps prevent accidents by allowing surrounding vehicles to anticipate your movements, enabling them to adjust their speeds or positions accordingly.

When drivers use directional signals, it promotes a clearer understanding of traffic patterns, thereby reducing the likelihood of misunderstandings or collisions. It's an essential aspect of defensive driving, ensuring that everyone on the road is aware of each other’s actions.

The other options address different aspects of driving but do not accurately capture the primary function of directional signals. For example, while they may contribute to pedestrian awareness or vehicle presence, the fundamental purpose is centered around communicating intentions to other drivers. Therefore, signaling before turning is key to fostering harmonious and safe interactions on the roadway.
