What is the purpose of signals while driving?

Signals play a crucial role in promoting safety and communication among drivers on the road. The primary purpose of using signals while driving is to indicate an intention to turn. This allows other road users, including drivers and pedestrians, to anticipate what a driver plans to do next, thereby reducing the risk of accidents. When a driver uses a turn signal, it clearly communicates their intent, helping to create a smoother flow of traffic and enhancing overall road safety.

While warnings about speed limits, guidance for pedestrians, and indications of emergency stops are important aspects of road safety, they are not the primary function of vehicle signals. Instead, signals are specifically designed to alert other motorists about a driver's forthcoming maneuver, such as turning left or right or changing lanes. This clarity is essential for effective road sharing and ensuring that all road users can make informed decisions based on the actions of others.
