What is the purpose of turn signals?

Answer: B — To indicate your intention to turn or change lanes

Turn signals serve a critical function in driving by indicating a driver's intentions to other road users. When a driver activates their turn signal, it communicates to those around them that they plan to make a turn or change lanes. This helps in ensuring safety on the road, as it allows other drivers, pedestrians, and cyclists to anticipate movements and adjust their actions accordingly. This practice is essential in preventing accidents, as it reduces uncertainty among road users, allowing for smoother traffic flow. By signaling intentions, drivers contribute to overall road safety and cooperation among all vehicles and individuals on the roadway. The other choices do not relate to the primary function of turn signals and therefore do not accurately reflect their purpose.
