Why is it important to use turn signals?

Using turn signals is crucial because they communicate your intentions to other drivers and road users. By signaling before you change lanes, turn, or merge, you help create a shared understanding of what you plan to do, which enhances safety on the road. This allows other drivers to anticipate your actions, reducing the risk of accidents and confusion.

The other options fail to capture the primary purpose of turn signals. Making a car look modern is irrelevant to safety and the function of turn signals. Claiming that signaling is only necessary during bad weather misrepresents the consistent need for communication on the road, regardless of weather conditions. Lastly, turn signals do not inherently allow for faster lane changes; they serve a communicative function rather than influencing the speed at which a driver can change lanes. This emphasizes the importance of signaling for safety and effective communication while driving.
