Rules of the road??

And remember there are honks, and then there are honks.

As has been pointed out here before, in many states it's technically required to give an audible signal before passing on a two-lane road. A driver who taps their horn when they're four or five car-lengths behind you is probably just trying to be courteous.

I totally get that one...I grew up in an area with a huge amount of bikers and to be safe I always did a short honk to notify them that I was there. I wasn't sure if that was the right thing to do or if I was making them upset but I wanted them to know I was there. Thanks for the info!
