Why is using turn signals important?

Using turn signals is essential because they inform other drivers of your intentions to turn or change lanes. This communication helps to ensure that everyone on the road is aware of each other's actions, which significantly enhances safety. When drivers use turn signals, they provide critical information that allows surrounding vehicles and pedestrians to anticipate movements and react accordingly, reducing the likelihood of accidents. Proper signaling not only aids in smoother traffic flow but also fosters a culture of mutual respect and awareness among road users.

The other options, while relating to vehicle performance, do not address the primary function of turn signals, which is to communicate intent. Swift turning, engine problems, and fuel efficiency are important topics within driving, but they are not the main reason for the use of turn signals. The act of signaling is fundamentally about safety and transparency on the road.
