What is the purpose of using turn signals?

Using turn signals is essential for safe driving as they serve as a communication tool between drivers on the road. By signaling your intentions, such as a lane change or turn, you help others understand what you plan to do. This reduces the risk of misunderstandings or accidents since other drivers can anticipate your movements and react accordingly. Clear communication is a key aspect of road safety, and turn signals play a crucial role in fostering cooperation among drivers.

The other choices relate to different aspects of vehicle operation but do not pertain to the primary purpose of turn signals. Indicating vehicle speed is a function of the speedometer, malfunctioning brake lights indicate a need for vehicle maintenance, and warning of potential skids pertains to loss of traction rather than signaling intentions on the road. Each of these serves a different safety function but does not specifically communicate a driver's intentions like turn signals do.
