Loud air horns can really get you in trouble, all the years I drove truck I hardly ever heard a truck air horn out on the road. How often have you heard a truck use their air horn out on the road, it's not like the movies that everytime you see a truck they blow their horn.
You don't know what a numb headed motorist texting or god knows what will do when you light off a loud air horn close to them. Blowing a horn at somebody won't change what they are doing and you might just find the one with a case of road rage. You just have to drive with the knowledge that they will do almost anything at anytime, you have to drive for yourself and everyone else around you at all times. After awhile you will be able to know what they are going to do before they do.
