How far ahead should you signal before making a turn?

Answer: B — At least 100 feet

The correct distance to signal before making a turn is at least 100 feet. Signaling at this distance allows other drivers and pedestrians enough time to react to your intentions. Proper signaling is essential for safe driving, as it communicates your actions to others on the road, helping to prevent accidents and maintain a smooth flow of traffic. While some might consider shorter distances, 100 feet strikes a balance between being noticeable without being impractical. It ensures you are providing adequate notice in various driving conditions, such as during higher speeds or in busy intersections. The other distances mentioned, while they may seem reasonable, do not provide the optimal amount of time and space that 100 feet does for signaling effectively.
