In residential areas, how many feet prior should you signal your turn?

Answer: B — 100 feet

In residential areas, signaling your turn at least 100 feet in advance is essential for ensuring that both you and other road users can react safely to your actions. This distance allows enough time for vehicles behind you and those preparing to cross your path to recognize your intentions and adjust accordingly. Signaling early helps maintain the flow of traffic and reduces the likelihood of sudden stops or last-minute maneuvers, which can lead to accidents. Given the shorter distances and potentially higher pedestrian activity in residential areas, it is particularly crucial to communicate your turning intentions effectively to avoid any misunderstandings or collisions.
