When should you use your turn signal to indicate a lane change?

Pick an answer

1. Early enough that other drivers have time to react before you actually move over
2. Only after you've already started moving into the next lane, which sounds right but isn't, at least for change
3. Only after you have already completed the lane change
4. At the exact moment you begin steering into the new lane
