Michigan has this buried in its vehicle code, and I've never seen another State's code that was significantly different: "Sec. 657. Every person riding a bicycle or moped upon a roadway shall be granted all of the rights and shall be subject to all of the duties applicable to the driver of a vehicle by this chapter, except..." Using this wording, a bicycle is a pseudo-vehicle. It is required to follow vehicular regulations regarding speed, which side of the road to drive on, etc. But at the same time, this wording implicitly states that bicycles are not vehicles.

My driver's license is labeled an "Operator License." Not very specific, is it?
