What is the purpose of using turn signals?

Using turn signals serves the primary purpose of indicating your direction to other drivers. This communication is essential for safe driving, as it allows other road users to anticipate your movements, whether you’re making a turn, changing lanes, or merging onto another road. By signaling your intentions well in advance, you help create a safer driving environment for everyone, reducing the likelihood of collisions or misunderstandings about your intended actions.

In addition to this, effective use of turn signals is mandated by traffic laws in many jurisdictions. This legal aspect reinforces the importance of signaling as a standard practice in responsible driving.

The other choices do not accurately reflect the primary function of turn signals. For instance, signaling a stop is generally done using brake lights rather than turn signals. Alerting other drivers of speed is unrelated to signaling intentions, and not using headlights is not a function of turn signals. Each of these alternatives misses the critical role that turn signals play in facilitating clear communication between drivers on the road.
