If you are a constant social media user, chances are you would have come in contact with a lot of internet slang or phrase, which by luck, you were able to interpret some and some seemed unclear to you. One of those phrases is Horn OK Please. The phrase is something very common in India. The phrase is often seen on Trucks, Lorries, Bus and articulated vehicles.
The phrase is usually written at the back of a vehicle very boldly. It is not for decoration but it is aimed at informing the driver of a vehicle coming from behind to try to horn so that he would be aware someone is planning to overtake his vehicle.
The main idea about this phrase on vehicles is to reduce accidents that are usually a result of reckless driving on the road. But we all know how people can be playful with some things, the phrase is no longer being used in India because it was turning into noise pollution.
