How far ahead should you signal before making a turn?

Answer: C — At least 100 feet

Signaling a turn at least 100 feet in advance is important because it provides sufficient time for other road users to be aware of your intentions. This distance allows drivers behind you to react appropriately by slowing down or changing lanes if necessary, thereby enhancing safety on the road. It also gives pedestrians and cyclists enough time to understand your direction of movement, allowing them to react accordingly. In many jurisdictions, including Idaho, this guideline helps maintain predictable traffic flow and reduces the likelihood of accidents due to sudden movements. Adhering to this distance is part of responsible driving practices aimed at ensuring safety for everyone on the road.
