What is the purpose of using turn signals while driving?

Using turn signals while driving is primarily to inform other drivers of your intentions. This communication is crucial for the safety of all road users, as it helps prevent accidents by allowing other drivers to anticipate your movements, such as when you plan to change lanes, make a turn, or merge into traffic.

While compliance with driving laws is also important, the primary purpose of turn signals transcends merely following regulations; it enhances safety by fostering clear communication on the road. The use of turn signals is fundamentally about ensuring that each vehicle operator understands the actions of others, which helps maintain a smoother flow of traffic and reduces the likelihood of collisions.

Fuel efficiency and engine wear are not directly related to the operation of turn signals, making other options less relevant in the context of their primary function.
