It varies by state. Here in PA, if you have more than 25 bikes, you are allowed to roll on through, however it's a good idea for the bikes in front to block traffic from the other directions because it's doubtful the cagers who are getting impatient know about the law.
When I'm riding in a small group (3-4), we usually pull out as a single unit and the drivers at the intersection are courteous enough to accept it.
Check with your state's AMA or ABATE chapter. They should be able to answer all your questions.
My other rules for group riding
: (in no particular order)
1. Do not take good lines - taking the right line is frowned upon in large group rides. Stay parallel to the lines on the road and ride the same speed as everyone else. Try to look cool, but don't have any fun (can you tell how much I love group rides?).
2. Don't drag your brakes or slow down around turns. It annoys people, especially me.
3. Don't ride beside someone you don't know (not even staggered) - It's one of my pet peeves. The trailer crowd down in Myrtle Beach this year were horrible about trying to share my lane. I don't know their skill level (or intoxication level) and they don't know mine. Stick with those you know and trust. Even then, give yourselves room to react.
4. Don't complain about your arse hurting after only an hour or two. It just shows that you don't really ride anywhere except to the pub and back.
5. Just because the road captain pulls out, that doesn't mean there is enough room for you to pull out. Always check for traffic, no matter what everyone else is doing.
That's all I can think of for now. Hopefully others will add to the list.
