What is the primary purpose of a vehicle's turn signals?

1. To alert pedestrians

2. To indicate a driver’s intention to turn or change lanes

3. To signal for help

4. To warn other drivers of hazards

The correct answer is: To indicate a driver’s intention to turn or change lanes

The primary purpose of a vehicle's turn signals is to indicate a driver’s intention to turn or change lanes. Turn signals serve as a critical communication tool between drivers and other road users, helping to prevent misunderstandings and potential accidents. When a driver activates the turn signal, it clearly communicates to others on the road their planned maneuvers. This allows surrounding drivers and pedestrians to anticipate changes in traffic flow, which helps maintain safety on the road. While alerting pedestrians is important, turn signals specifically focus on conveying a driver's upcoming actions rather than simply notifying pedestrians. Signaling for help relates to emergency situations, which is not the intended function of turn signals. Finally, while signals can sometimes help warn drivers of hazards, their main role is to indicate turning or lane-changing intentions. This focus on movement intentions makes turn signals an essential aspect of safe driving practices.
