How far should you signal before making a turn?

Answer: B — At least 100 feet

Signaling at least 100 feet before making a turn is important for safety and communication with other road users. This distance allows other drivers, as well as pedestrians, to anticipate your actions and adjust their speed or position accordingly. By providing this clear notice in advance, you reduce the risk of accidents and promote smoother traffic flow. Additionally, this practice is aligned with traffic laws in many areas, which require adequate signaling distance to ensure that your intentions on the road are unmistakable. The other options represent varying distances that are generally considered too short for effective signaling, which may not give other drivers enough time to react.
