How far in advance should a driver signal their intention to turn?

Answer: D — 200 feet before turning

In Indiana, drivers are required to signal their intention to turn at least 200 feet before reaching the intersection where the turn will be made. Signaling in advance allows other drivers, pedestrians, and cyclists to anticipate the driver's actions, promoting smoother traffic flow and reducing the risk of accidents. Therefore, option D is the correct answer as it aligns with Indiana's signaling guidelines.
