What is the primary reason for using turn signals?

Answer: B — To communicate with other drivers

The primary reason for using turn signals is to communicate with other drivers. By signaling before making a turn or changing lanes, a driver informs other road users of their intentions. This communication is crucial for maintaining safety on the roads, as it helps prevent accidents by making it clear what actions the driver is about to take. Other drivers can respond appropriately, whether by adjusting their speed, changing lanes, or otherwise preparing for the driver's maneuver. While complying with road regulations is important, the essence of using turn signals centers on the aspect of communication, ensuring that everyone shares the road safely. Alerting the police or considering fuel consumption are not relevant to the fundamental purpose of turn signaling, which is primarily about sharing intentions with fellow road users.
