How far in advance should you signal before making a turn?

Signaling before making a turn is essential for ensuring safety on the road and communicating your intentions to other drivers and pedestrians. The recommendation to signal at least 100 feet before making a turn gives other road users sufficient time to react and adjust their behavior accordingly. This distance helps to enhance the predictability of your actions, allowing vehicles behind you and those approaching the intersection to be aware that you intend to turn.

Other distances, like those mentioned in the other options, may not provide enough time for everyone to understand and respond to your turn, potentially increasing the risk of accidents. Signaling too late can lead to confusion and may result in dangerous situations, especially in busy traffic areas. Therefore, the 100-foot guideline strikes a practical balance, ensuring safety while also adhering to traffic laws that govern signaling.
