It address the shoulder issue here:It addresses the shoulder in the fact that the shoulder is not actually part of the road. As I mentioned before, the law doesn't recognize it as a legal place for a cyclist to ride. So this comes back to my view that you have to use your judgement. I ride in the shoulder where it makes sense, but at most intersections I'll come of the shoulder into the lane and take the lane.
As mentioned before, it's a continually changing thing. Some intersections I'll do this because I want to be out and visible for any cars that would make a right at the intersection possibly killing me. If there's a turning lane, I'm definitely in the lane of the direction I'm going. Some roads with a clear shoulder through the intersection I won't be in the lane.
It's not easy, our infrastructure sucks, and the laws aren't always clear. Balancing act of not being a asshole and staying alive.
39:4-14.2, 39:4-10.11 Operating Regulations. Every person riding a bicycle on a roadway shall ride as near to the right roadside as practicable, exercising due care when passing a standing vehicle or one proceeding in the same direction. A bicyclist may move left under any of the following conditions:
The roadside is the edge of pavement to edge of pavement as per the FHWA rules for what is the roadway. The shoulder is within the roadway. This is further supported in the law where it says you can move into the lane.
At the end of the day, most drivers do not care about the laws of bicyclist.
