The turning lights of a car, also known as wink, play a key role in streets, routes and highways because they serve to clearly inform the intention to turn or change lanes. Their use is mandatory since it is written in National Transit Law (article 42, paragraph F); however, many omit it by carelessness or laziness, generating unexpected maneuvers that endanger road safety.
