How far in advance should you signal before making a turn?

Answer: B — At least 100 feet

Signaling at least 100 feet before making a turn is essential for ensuring that other drivers and pedestrians have adequate notice of your intentions. This distance allows sufficient time for surrounding vehicles to react accordingly, helping to maintain safety on the road. It is particularly important in urban settings where traffic can be more congested and where other road users may need to adjust their speed or position in response to your signaling. In some instances, approaching intersections or turns may vary the required distance based on the specific road conditions and speed; however, the 100-foot recommendation strikes a good balance for most situations. This practice encourages safe driving behavior and compliance with traffic laws, reinforcing the need for clear communication with other road users.
