What's in a Horn?

Possible meanings of a car horn when driving in Guangzhou:

“I am preparing to turn left into the path of oncoming traffic. I hope you see and avoid me.”

“I am making a blind right turn around a parked truck. Anyone beyond the truck, beware.”
“I am driving faster than you, so I advise you to speed up or change lanes.”
“The road narrows ahead. Be sure you leave enough room for my car on your right/left.”
“You need to slow/stop your bicycle, or I will probably hit you.”
“I am running a red light… just so you all know, I’m here in the middle of this intersection…”
“That pedestrian in the crosswalk ahead isn’t moving fast enough for my liking.”
“I am turning right and merging into oncoming traffic, and I don’t want to have to use my brake pedal, so everyone please slide to your left.”
“I know this is a 3-lane road based on the suggestive white paint on the pavement, but we can surely fit at least 5 vehicles across and still leave plenty of room for the bicycle commuters…”
“My turn-off is 50 meters ahead… I will make a slow gradual turn across 3 lanes of traffic at this point.”
“FYI – I’m passing you on your left. We are currently not on a collision course, but why don’t we just continue to maintain our current lanes?”

Viel spass!!
