When should you use your turn signals?

Using your turn signals is essential for safe driving. You should activate your turn signals whenever you are turning, changing lanes, or merging. This practice is designed to communicate your intentions to other drivers on the road, which helps prevent accidents and enhances overall road safety. By signaling your movements, you give other road users the chance to anticipate your actions, leading to smoother traffic flow and reducing the risk of collisions.

The other choices do not emphasize the importance of consistently using turn signals. For instance, signaling only when other vehicles are present limits communication to conditions where other drivers are nearby, rather than when everyone on the road should be informed. Similarly, only signaling in heavy traffic ignores safe practices that should be maintained at all times, regardless of traffic conditions. Finally, using signals based solely on personal judgment can lead to inconsistency and confusion, making the roads less predictable and potentially hazardous for everyone.
