When should you use your turn signal?

Using your turn signal before making any turn or lane change is essential for safe driving. This practice communicates your intentions to other drivers, pedestrians, and cyclists on the road, thereby reducing the risk of accidents. It allows others to anticipate your movements, making it easier for them to react appropriately, whether that means giving you space to maneuver or adjusting their own driving behavior.

Signaling is a fundamental aspect of driving etiquette and legal compliance; most traffic laws require drivers to signal their intentions in advance of a turn or lane change. By doing so, you contribute to a safer driving environment for everyone. This proactive communication helps prevent confusion or misinterpretations of your actions, which are common causes of collisions.

In contrast to the other options, signaling after a turn, only when changing lanes, or when entering a roundabout does not provide the same level of communication and safety, since those actions can be misleading without prior indication of intent.
