That is the case in California, but it's pretty well established in conventional wisdom that they're collectively little off in general, being a rare example of a state that permits cyclists on a single freeway, and otherwise hates on them as a rule. In most states and the vast majority of provinces, bicycles are generally permitted except on older sections that lack proper shoulders or have exceptionally difficult-to-cross ramps, in which case it's explicitly posted at the entrance to this effect anyway. As a rule in the US and Canada, all modes are permitted unless explicitly excluded per the MUTCD. Only 23 states and as far as I'm aware no provinces ban bicycles on all freeways (all of them east of the Mississippi, and most of them with Atlantic Ocean frontage), and in the states where they are banned, it's posted at the entrance ramps to that effect if they want to be compliant with the MUTCD (a requirement for federal highway funding). Alberta and British Columbia actually have bicycle facilities built into the design of the TransCanada Highway sharing pavement with motorists, with signs, if not special over/underpasses at entry and exit ramps to facilitate ramp crossings for cyclists. > the wiki states for the USA http://wiki.openstreetmap.org/wiki/Highway > motorway = "Limited access freeway with interchanges." > In my reading every highway which is not limited access should not be > tagged as motorway, be it in north america or elsewhere. Limited access refers to physical access, not access by mode. There's a limited number of intersections (if any), and no driveways (unless there's physically no other way to get to that parcel).
