What is the significance of using turn signals while driving?

Answer: B — To inform other drivers of your intent

Using turn signals while driving is essential because they serve the primary purpose of informing other drivers of your intended actions. When you signal before a turn or lane change, you provide critical information to those around you, enhancing safety on the road. It helps to prevent accidents by enabling other drivers to anticipate your movements, ensuring that they can adjust their speed or position accordingly. While some may view signaling as a courtesy, the reality is that it plays a fundamental role in safe driving practices. It is not optional; rather, it is a legal requirement in most jurisdictions, including Washington. Moreover, it is not limited to residential areas; signaling is important in all types of driving environments, whether on highways, city streets, or rural roads.
