So I am a fairly new rider and brand new to this forum but I have a question as it happened last night. So there I am riding down the highway when I see a small group of about 4-5 riders. Its a two laner and I was in the left, well there was a big gap in between the rear two and the front two granted I don't actually know if they were riding together since they all got off different exits. Anyway I jumped into the middle of the group because I felt it would be safer for me. I just wanted to know your opinions on this and what the road rules say about joining a group ride when you aren't part of it.
