Why is it critical to use turn signals?

Using turn signals is critical because they serve the essential purpose of informing other drivers of your intentions on the road. When you activate your turn signal, you communicate to other motorists and pedestrians that you plan to change lanes or make a turn. This communication is vital for maintaining safety and minimizing the risk of accidents. By signaling your intentions, you provide other drivers with the information they need to adjust their actions accordingly, which promotes a smoother and more predictable flow of traffic.

While checking vehicle lights, adhering to safety standards, and reducing fuel consumption are all important aspects of vehicle operation and safety, they do not directly relate to the primary function of turn signals. The primary goal of using turn signals is to ensure that other road users are aware of your next move, allowing them to react and maintain safety on the road.
