This is an excellent topic that should be pursued with more detail with regard to the passengers responsibility. I don't ride 2-up and neither does my wife. We have our own bikes and neither of us will take riders nor will we be a passenger unless there is a serious emergency that would require it and only if no other transportation is available.
I'm sure there is a website that discusses this issue but I just don't know where. If anyone knows of a website maybe they could put in a link or paraphrase the information.

Thanks for getting this important topic started Badbob. I see too many (especially younger less experienced) riders taking passengers that do some dangerous riding in and out of traffic. Most of the time it is their girlfriend who enjoys the thrill but has no concept of how to be a safe passenger.

Cheers!
