How far in advance should you signal before turning?

Answer: C — At least 100 feet

Signaling your intentions well in advance is essential for maintaining safety on the road and ensuring that other drivers and pedestrians can react appropriately to your actions. The recommended distance to signal before turning is at least 100 feet. This gives adequate time for vehicles behind you and those at intersections to understand your intentions and prepare to yield or adjust their speed as necessary. When driving, providing a clear indication of your intended movements helps to prevent misunderstandings and accidents. The 100-foot guideline is based on the average stopping distance and the time it takes for other drivers to notice your signal, comprehend it, and potentially alter their behavior in response to your turn. Shorter signaling distances may not provide sufficient time for the surrounding traffic to react, leading to unsafe situations. On the other hand, signaling too far ahead could become confusing in fast-moving traffic or busy intersections, but 100 feet strikes a good balance for urban and suburban driving environments.
