How far in advance should you signal before making a turn?

The correct response is that you should signal at least 30 meters before making a turn. This distance is crucial because it provides adequate warning to other drivers and pedestrians of your intentions to turn, facilitating smoother traffic flow and enhancing safety. By signaling 30 meters in advance, you give approaching vehicles time to react appropriately, which is especially important in busy areas where last-minute maneuvers could lead to accidents.

Signaling too close to the turn might leave other drivers unaware of your intention, increasing the risk of collisions or confusion, particularly in congested traffic situations. The recommended distance of 30 meters thus serves to ensure clarity and predictability on the road, allowing for a better driving environment for everyone.
