How far in advance should you signal your intention to turn?

Signaling your intention to turn is a crucial part of safe driving practices, as it informs other road users of your intentions, thereby reducing the risk of accidents. The correct answer of 100 feet before the turn is significant because it provides ample notice to drivers and pedestrians around you, allowing them time to react to your change in direction.

This distance is based on average travel speeds and helps ensure that your signal is visible and noticeable to others, making it easier for them to adjust their own driving behavior accordingly. In many jurisdictions, including Alaska, this is the standard recommended distance to provide adequate notice, promoting overall road safety.

Other options suggest either shorter distances or signaling too late, which could lead to confusion among other drivers and increase the potential for collisions. Proper signaling is not just a courtesy; it's a responsibility that contributes to the safety of all road users.
