Using turn signals is crucial because they serve as a means of communication between drivers on the road. When a driver activates a turn signal, it indicates their intention to change lanes, make a turn, or merge into another traffic lane. This not only alerts other drivers to their upcoming actions but also helps to prevent collisions and promote safer driving conditions.

Effective use of turn signals allows other drivers to anticipate the movements of a vehicle, which is essential in maintaining safe distances and avoiding accidents. Moreover, communicating intentions clearly can help to reduce confusion on the road, making it easier for all users—drivers, cyclists, and pedestrians—to navigate the traffic environment safely and efficiently.

In contrast, maintaining vehicle speed, signaling emergency situations only, or reflecting vehicle color changes do not contribute to the overall safety and communication aspects that turn signals fulfill. Thus, the ability to signal intentions is fundamentally about enhancing road safety through effective communication.
