At what distance should you signal before making a turn?

Signaling at least 100 feet before making a turn is important because it provides adequate notice to other drivers and pedestrians of your intended maneuver. This distance allows other road users to react safely and adjust their behaviors accordingly, which is particularly critical in busy traffic situations.

Using this distance ensures that anyone around you can see your signal and anticipate your move well in advance, which contributes to overall safety on the road. Traffic rules emphasize this practice because it minimizes the risk of collisions by ensuring that everyone is aware of each other's intentions.

It's also worth noting that signaling too late or not at all can lead to confusion and unpredictable driving behavior, increasing the risk of accidents. Thus, the 100-foot rule supports the principle of defensive driving by promoting clear communication on the road.
