Which of the following is a method to communicate with other drivers?

Using turn signals is a fundamental method to communicate with other drivers. They provide clear indications of your intended actions, such as turning or changing lanes, helping to enhance safety on the road. When you use turn signals, you're informing others of your movements in a standardized way that most drivers understand. This helps prevent accidents and improves overall traffic flow by allowing others to anticipate your actions.

While hand gestures and flashing headlights can sometimes convey messages, they are not as universally recognized or reliable as turn signals. Depending on the context, using your phone is discouraged while driving since it can distract you from the road and reduce your awareness of other drivers. Therefore, using turn signals stands out as the most effective and safest way to communicate your intentions while driving.
