What is the required minimum distance to signal before turning or changing lanes?

Answer: B — 100 feet

The required minimum distance to signal before turning or changing lanes is 100 feet. This distance allows other drivers and pedestrians adequate time to recognize your intention to turn or change lanes, thus improving overall safety on the road. Signaling within this timeframe helps create a predictable driving environment, allowing other road users to anticipate your actions. This is particularly important in maintaining safe distances and avoiding collisions, especially in busy or high-traffic areas. It's essential to signal early enough to give ample warning, as this promotes more effective communication with other drivers and enhances traffic flow.
