How far ahead should you signal before making a turn?

You should signal at least 100 feet before making a turn to ensure that other drivers and pedestrians have adequate time to understand your intentions. This distance is significant because it allows sufficient reaction time for those around you to notice your signaling and adjust their driving accordingly.

Signaling too close to the turn may not give other road users enough notice, potentially leading to misunderstandings or accidents. The 100-foot guideline is a practical standard that balances visibility and safety, particularly in urban areas where traffic is more congested and reactions need to be quicker.
