When must you use your turn signals?

Using turn signals is essential for indicating your intentions to other road users. They serve as a communication tool that helps maintain safety on the roads by alerting other drivers and pedestrians about your planned actions. This is crucial not only when turning at intersections but also when changing lanes, merging, or entering roundabouts. Engaging your turn signals whenever you intend to turn or change lanes ensures that those around you can anticipate your movements and react accordingly, which helps prevent accidents and enhances overall traffic flow.

In contrast, using turn signals only during lane changes would neglect the important need to signal at intersections or when making turns. Similarly, signaling only when other cars are nearby may lead to confusion, as drivers need clear communication regardless of their proximity. The idea of signaling only when it's dark outside disregards the fact that safe driving practices should be consistent at all times, regardless of lighting conditions.
