How far should you signal before turning or changing lanes?

The correct choice emphasizes the importance of signaling at a sufficient distance to ensure safety and clear communication with other road users. Signaling at least 50 meters before turning or changing lanes is recommended as it allows other drivers, cyclists, and pedestrians enough time to react to your intentions. This distance helps prevent misunderstandings on the road, as it gives other individuals ample opportunity to adjust their actions, thereby enhancing overall road safety.

Signaling too close to the maneuver—such as only a few meters away—may not give other drivers enough time to respond appropriately, potentially leading to dangerous situations. By indicating your intentions 50 meters in advance, you contribute to a smoother flow of traffic and promote safer driving practices for everyone on the road.
