What is the role of turn signals in vehicle safety?

Turn signals play a critical role in vehicle safety by indicating the driver's intentions to other road users. When a driver activates their turn signals, it communicates to nearby vehicles and pedestrians that a maneuver is about to occur, such as a turn or a lane change. This advance notice allows other drivers to adjust their speed and position accordingly, thereby reducing the likelihood of collisions.

Effective use of turn signals is essential in promoting safe driving habits and ensuring that all road users are aware of each other’s movements, which is particularly important in busy traffic situations. By following these signaling practices, drivers can contribute to maintaining a safer road environment overall.

The other options do not accurately reflect the primary function of turn signals. They are not designed for aesthetic enhancement, are not limited to nighttime use, and are not optional, even in urban driving scenarios where frequent turns and lane changes occur. Their use is a fundamental aspect of adhering to traffic laws and ensuring both personal and public safety on the road.
