When you are pulling away from the side of the road, how many feet ahead should you signal?

Answer: B — 100 feet

Signaling before pulling away from the side of the road is crucial for safety and communication with other drivers. The correct distance to signal is 100 feet ahead of the maneuver. This allows enough time for drivers behind you to notice your intention to merge back into traffic, providing them with the opportunity to maintain a safe distance and adjust their speed if necessary. Signaling 100 feet ahead is a standard practice as it gives drivers adequate time to react, helps to ensure that the maneuver can be performed safely, and reduces the risk of accidents. This distance strikes a balance between being too early, which could confuse other drivers, and being too late, which may not provide sufficient warning.
