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

Signaling a turn is an important part of safe driving practices, as it communicates your intentions to other road users and helps prevent accidents. The correct answer of 100 feet is based on standard recommended practices for signaling before making a turn. This distance allows other drivers and pedestrians sufficient time to react to your intention to change direction.

When you signal 100 feet in advance, you're giving ample notice that you're about to turn, which aligns with various traffic regulations that encourage drivers to signal well in advance of actually making the maneuver. This distance is generally considered appropriate under typical driving conditions, allowing for adequate processing time for others on the road.

While shorter distances, such as 50 or 75 feet, may not provide enough notice for other drivers, signaling too late can surprise others and lead to unsafe driving situations. Signaling too far in advance, like at 150 feet, could also create confusion, particularly in complex traffic situations. Thus, 100 feet strikes an effective balance in ensuring clear communication without causing misunderstandings among road users.
