What is the purpose of turn signals?

The purpose of turn signals is multifaceted, serving essential functions for safety and communication on the road. When a driver uses turn signals, they are primarily notifying other drivers of their intentions, which is crucial for maintaining safe driving practices. This communication includes not only indicating a lane change but also alerting other road users of an upcoming turn or maneuver.

By signaling, drivers allow others to anticipate changes in traffic flow, which helps prevent accidents. For example, if a driver intends to switch lanes, using a turn signal provides a warning to nearby vehicles and pedestrians, allowing them to react appropriately. This enhances the overall safety of all road users by making intentions clear and reducing the chances of misunderstandings or sudden stops.

Furthermore, using turn signals is a legal requirement in many regions, including Maine, reinforcing the importance of this communication tool in promoting roadway safety.
