When should you use your turn signal?

Using your turn signal is essential for safe driving and helps communicate your intentions to other road users. The correct answer emphasizes that turn signals should be used when changing lanes or turning, which includes both left and right turns. This practice is vital because it informs other drivers and pedestrians of your actions, allowing them to anticipate your movements and adjust accordingly.

For instance, signaling before changing lanes helps prevent accidents by ensuring that other drivers are aware of your intentions to move into their path or merge with traffic. Similarly, signaling when making a turn—whether left or right—alerts those behind you and in the vicinity to your upcoming maneuver, promoting safer road conditions for everyone.

While the incorrect choices touch upon aspects of using turn signals, they lack the comprehensive scope required for safe driving practices. For example, signaling only left turns or using the signal solely when other cars are nearby does not encompass the full need for signaling in various driving scenarios. Likewise, signaling after completing a turn does not provide any advance notice to other drivers, defeating the purpose of using a turn signal effectively.
