Why is it essential to use turn signals?

Using turn signals is essential primarily because it indicates your intentions to other drivers on the road. When you signal your next move—whether it's turning, switching lanes, or merging—other drivers gain crucial information about your actions. This communication helps to create a predictable driving environment, which significantly reduces the chances of collisions. By signaling, you reduce uncertainty and allow others to adjust their speed and position accordingly, enhancing overall safety for everyone on the road.

In contrast, while avoiding police fines may be a consequence of not using turn signals, that is not the primary purpose of them. Notifying pedestrians of your presence is important but does not encompass the primary function of turn signals. Additionally, improving fuel efficiency is unrelated to signaling; it focuses more on driving behaviors rather than communication between vehicles. Thus, the correct answer emphasizes the critical role of turn signals in promoting safe and informed driving practices.
