What is the purpose of using turn signals?

The purpose of using turn signals is to alert other drivers of your intentions on the road. This communication is crucial for ensuring safety and coordination among road users. When a driver signals their intention to turn or change lanes, it provides advance notice to others, allowing them to adjust their speed or position accordingly. This reduces the risk of accidents and helps maintain a smooth flow of traffic.

While notifying pedestrians of traffic or indicating vehicle malfunctions are important in their own right, they do not specifically pertain to the primary function of turn signals. Similarly, changing dashboard lights is a vehicle feature unrelated to driving intentions. Thus, the primary and critical role of turn signals remains in informing other motorists of your upcoming maneuvers.
