At what distance should a driver signal before making a turn?

Answer: B — 100 feet

Signaling before making a turn is essential for ensuring safety on the road, as it communicates the driver's intentions to other road users. The recommended distance for signaling is typically at least 100 feet before the turn. This gives sufficient warning to drivers behind you and other road users, allowing them to adjust their speed or position accordingly. Signaling too close to the turn may not provide other drivers enough time to react, which could lead to unsafe situations. While some jurisdictions or road conditions might necessitate different distances, the 100-foot guideline is a widely accepted standard that balances safety and clarity. By signaling at this distance, you help create a more predictable driving environment for everyone on the road.
