Using turn signals is a critical aspect of safe driving and effective communication with other road users. The purpose of turn signals is to inform others of your intentions on the road. When you signal whenever you intend to change direction, you are actively notifying drivers, pedestrians, and cyclists of your planned movement. This includes not only turns at intersections but also lane changes, merging, and any other actions that could affect the flow of traffic.

By consistently using your turn signals, you enhance safety and reduce the risk of collisions. For instance, signaling a lane change alerts the driver in the adjacent lane, allowing them to maintain a safe distance or adjust their speed accordingly. Similarly, signaling when making a turn lets vehicles behind you know that you are slowing down, which can help prevent rear-end accidents.

The other options suggest limited use of signals, which could lead to confusion and unsafe situations on the road. It's essential to develop a habit of signaling every time you intend to change direction to promote safer driving for everyone.
