In what situation is it required to use turn signals?

Using turn signals is crucial for communicating your intentions to other drivers on the road, particularly when changing lanes or making turns. Signaling allows other motorists, cyclists, and pedestrians to anticipate your next move, thereby enhancing safety and reducing the likelihood of accidents.

When you are preparing to change lanes, signaling lets drivers behind and beside you know that you are about to move into their path, allowing them to adjust their speed or position if necessary. Similarly, using turn signals when making a turn is essential for alerting others that you are altering your direction, which is especially important at intersections where multiple vehicles and pedestrians are present.

While signaling is important in various other scenarios, such as merging onto a freeway or when driving in a parking lot, the requirement to use turn signals specifically applies to changing lanes and making turns as part of proper driving etiquette and safe roadway practices.
