Turn signals serve a critical purpose in road safety by informing other vehicles and pedestrians of your driving intentions. When a driver uses turn signals, they communicate their upcoming actions, such as turning left or right, or changing lanes. This allows other road users to anticipate and adjust their behavior accordingly, reducing the likelihood of accidents.

Using turn signals is especially important in situations where visibility may be limited, or where other drivers may not be aware of your intentions. Proper use of turn signals helps establish predictability on the road, enhancing overall traffic flow and safety. Other options may touch on related aspects of driving, such as signaling for lane changes or attracting attention, but the primary and most important function of turn signals is to inform others of your intended maneuvers.
