What is the primary purpose of using turn signals?

The primary purpose of using turn signals is to indicate intentions and reduce accident risks. Turn signals communicate a driver's planned actions to other road users, such as changing lanes, merging, or making turns. By signaling, drivers provide advance notice of their movements, which allows other drivers, cyclists, and pedestrians to anticipate their actions and react accordingly. This practice is a critical element of road safety, as it can help prevent collisions that may occur when drivers make sudden maneuvers without warning.

Other options do not align with the main function of turn signals. Confusing other drivers is the opposite of what signals are meant to do, while activating windshield wipers or adjusting vehicle speed are unrelated to signaling intentions on the road.
