What does signaling before a turn do?

Signaling before a turn indicates your intentions to other drivers, which is crucial for maintaining safety on the roads. When you signal, you communicate to others what you plan to do, allowing them to anticipate your movements. This helps create a predictable driving environment, reduces the risk of accidents, and assists in the smooth flow of traffic. Proper signaling can also encourage nearby drivers to adjust their speeds or positions appropriately, thereby enhancing overall roadway safety.
