In what scenario should you use your turn signal?

Using your turn signal is essential for safe driving, as it communicates your intentions to other road users. The correct answer emphasizes the importance of signaling when changing lanes or turning, which is crucial for maintaining safety on the road. By indicating your intended actions, you allow other drivers, cyclists, and pedestrians to anticipate your movement, thus reducing the risk of accidents.

In typical driving scenarios, applying your turn signal informs surrounding traffic that you plan to make a lane change or turn at an intersection. This practice is not only a matter of good etiquette but also a legal requirement in many jurisdictions, including Nevada.

The incorrect options highlight misconceptions around the use of turn signals. For instance, limiting turn signal use to specific situations like merging onto highways overlooks the need for signaling in everyday maneuvers. Similarly, considering turn signals optional in residential areas undermines the principle of clear communication, especially where pedestrians and cyclists may be present. Lastly, waiting for other drivers to signal first can lead to confusion and potential hazards on the road, as it places unnecessary reliance on others instead of actively communicating your own intentions.
