When should a driver use turn signals?

Using turn signals every time a driver changes direction, including when turning or changing lanes, is essential for ensuring safety on the road. Turn signals are a critical form of communication with other road users, indicating a driver's intentions to change direction or lane. By consistently using turn signals, drivers provide advance notice to pedestrians, cyclists, and other vehicles, helping to reduce the risk of accidents and promote smoother traffic flow.

While changing lanes is a key situation where turn signals are necessary, turning at intersections also requires clear communication to let others know what the driver plans to do. Consistent signaling reinforces predictable driving behavior, which is crucial for maintaining safety on busy roads. This practice is a fundamental rule of the road that applies universally, not just limited to certain environments or specific circumstances.
