Traffic Alert is a warning system used to alert drivers of potential hazards on the road. It is typically used in areas with high traffic volume or where there are frequent accidents. The term 'HONK' is commonly used as part of Traffic Alert, as it is a sound that can be heard from a distance and is easily recognizable. HONK is an acronym for 'High-pitched Oscillating Noise Klaxon', which is a type of siren used to alert drivers of potential danger.
