Sorry, I am a little confused. Perhaps a picture can fill in my blanks.

Intersection

I added a Google maps link above so show one intersection I encounter. Maybe with this you guys can describe what you are talking about above. I apologize for the ignorance. The majority of my bike riding was when I was a young sprout riding in residential streets. Being 32 and now seemingly more responsible I wanna make sure I don't kill myself or make some bone head move that would endanger anyone/anything. You can see the bike lane on the right and it just dumps out. Just to the right of the van up ahead is where the right turn only lane picks up.
