What is the primary purpose of activating a turn signal before a turn?

Activating a turn signal before making a turn is primarily intended to warn other drivers of your intention to change direction. This action enhances safety by clearly communicating your planned maneuver to surrounding vehicles, which allows them to adjust their speed and position accordingly. It helps to prevent accidents and miscommunication on the road, contributing to a more predictable driving environment for everyone.

The importance of indicating one's intentions cannot be understated in promoting road safety. When drivers are aware that another vehicle is about to turn, they can react appropriately, whether that means slowing down, changing lanes, or preparing to stop. This simple yet effective method of communication fosters a culture of mutual respect and awareness among road users.

While signaling can also inform passengers of upcoming turns, its primary function is aimed at other drivers, making them the focal point of the communication.
