What is the primary purpose of turn signals in a vehicle?

The primary purpose of turn signals in a vehicle is to alert other drivers of your intentions. When you use turn signals, you communicate to other road users that you plan to perform a maneuver such as turning or changing lanes. This communication is essential for maintaining safety on the road, as it helps prevent misunderstandings and reduces the risk of accidents.

The use of turn signals is part of a larger system of road communication that ensures all drivers are aware of each other's actions. By signaling your intentions, you give other drivers enough time to react accordingly, whether it's to yield, slow down, or change their own driving behavior. This is particularly important in busy traffic situations where clear communication can significantly enhance safety for everyone on the road.

Other options, while important in their own contexts, do not reflect the primary function of turn signals. Enhancing visibility at night, complying with registration requirements, and indicating speed do not specifically address the need for intention signaling, which is what turn signals are fundamentally designed to do.
