When must a driver use their turn signal?

A driver must use their turn signal at least 100 feet before making a turn to ensure that other road users are aware of their intentions. This practice is important for safety and helps to prevent accidents. Signaling in advance gives other drivers, pedestrians, and cyclists enough time to react to the driver's movements, allowing for smoother traffic flow and reducing the risk of collisions.

Using turn signals is not only a legal requirement in many areas, but it also promotes better communication on the road. It is essential to signal even when changing lanes or turning into a parking space to alert those around you to your actions, regardless of whether other vehicles are immediately nearby.
