If you press semicolon ( ; ) while driving a vehicle it will play the horn! There is a different horn sound for each vehicle.
Also, if you bind a key to 'playvehiclehorn 1' it will play a second, slightly more funny horn for each vehicle. Do that by entering:
set input "key" playvehiclehorn 1
At the console, where "key" is whatever key you want to bind it to.
