When must you signal before making a turn?

Signaling at least 100 feet before making a turn is important because it gives other drivers, pedestrians, and cyclists ample warning of your intentions. This distance allows for better communication on the road, reducing the chances of accidents. It gives following vehicles enough time to react appropriately, maintaining safety for all road users.

While some jurisdictions might have varied regulations, the 100 feet rule is designed to create a buffer for safe maneuvering. Signaling too close to the turn—such as immediately before, or even at shorter distances like 50 or 75 feet—can lead to confusion and make it difficult for others to predict your movements, especially in fast-moving traffic. By following this guideline, drivers can contribute to a safer driving environment.
