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

Signaling your intention to turn at least 100 feet in advance is essential for promoting safety on the roads. This distance gives other drivers and pedestrians adequate time to react to your intentions, ensuring they can adjust their speeds or positions accordingly. By providing this advance notice, you reduce the likelihood of confusion or potential accidents, particularly in busy or high-traffic areas where quick decisions are often necessary.

Additionally, the 100-foot signaling distance aligns with best practices outlined in traffic regulations, helping drivers maintain a smooth flow of traffic while also communicating effectively with others on the road. In comparison, shorter distances may not afford sufficient reaction time for those around you, while longer distances might be impractical in some driving situations, such as city environments with heavy traffic.
