Signaling before turning is crucial for ensuring the safety of everyone on the road. The guideline to signal at least 100 feet before making a turn allows other drivers and pedestrians to be aware of your intentions well in advance. This distance provides ample time for those around you to react appropriately, ensuring smoother traffic flow and reducing the potential for accidents.

The reasoning behind this specific distance is that it helps establish clear communication on the road. By signaling early, drivers can anticipate your actions, which is important in both urban and rural driving environments. It enhances safety not only for yourself but also for others who might be affected by your turn, such as pedestrians at crosswalks or vehicles sharing the same lane.

Using signals only when there are other vehicles around or just for changing lanes does not encourage proactive communication. It's essential to signal every time you intend to turn, regardless of the presence of other vehicles, to maintain a consistent awareness of traffic behaviors.
